  • Stainless Steel ” L” “H” Grade

    Austenitic grades are those alloys which are commonly in use for stainless steel applications. The austenitic grades are not magnetic. The most common austenitic alloys are iron-chromium-nickel steel and are widely known as the 300 series. The austenitic stainless steel tube, because of their high chromium and nickel content, are the most corrosion resistant of the stainless steel group providing unusually fine mechanical properties. They cannot be hardened by heat treatment, but can be hardened significantly by cold-working. Straight Grades The straight grades of austenitic stainless steel pipe contain a maximum of 0.08% carbon. There is a misconception that straight grades contain a minimum of 0.035% carbon, but the spec does not require this. As long as the material meets the physical requirements of straight grade, there is no minimum carbon requirement.“L” Grades The “L” grades are used to provide extra corrosion resistance after welding. The letter “L” after a stainless steel tubing type indicates low carbon (as in 304L). The carbon…

  • Corrosion Resistance of Stainless Steel Tubes

    Carbon steel suffer from ‘general’ corrosion, where large areas of the surface are affected. Stainless steel tubes in the passive state are normally protected against this form of attack, however, localised forms of attack can occur and result in corrosion problems. The assessment of corrosion resistance in any particular environment, therefore, usually involves a consideration of specific corrosion mechanisms. These mechanisms are principally: Other related mechanism can also occur, which include: Localised corrosion is often associated with chloride ions in aqueous environments. Acidic conditions (low PH) and increases in temperature all contribute to localised mechanisms of crevice corrosion and pitting corrosion. The addition of tensile strength, whether applied by loading or from residual stress, provides the conditions for stress corrosion cracking (SCC). These mechanisms are all associated with a localised breakdown of the passive layer. A good supply of oxygen to all surface of the steel is essential to maintaining the passive layer but higher levels of chromium, nickel, molybdenum & nitrogen all help…

  • Steel Overview

    Structural Carbon Steel | Structural Alloy Steel | Spring Steel | Rolling Bearing Steel | Free-machining Steel | Anti-friction Steel | Carbon Tool Steel | Alloy Tool Steel | High Speed Tool Steel | Stainless Steel | Heat-resisting Steel Steel is a term used for iron to which between 0.02 to 1.7% carbon has been added. The old definition of steel used to be something like “it rusts and it sinks in water.” This material comprises the most diverse group of alloys and applications in the metals world. If there is something that needs to be made, there probably is a steel alloy that it can be made of. Steel does, of course, have poor corrosion resistance, but its relatively low cost and ease of painting make it a common choice. The numbering system for steel is actually one of the few things in the metals industry that seems to make sense. You can determine…

  • Corrosion Resistant Stainless Steel Tube

    In our product programme we offer our customers two classes of Stainless Steel grades that have an excellent resistance to corrosion stainless steel Austenitic-ferritic Duplex stainless steel are characterised by their excellent mechanical qualities, particularly their high stress corrosion cracking resistance. They are especially well-suited for maritime applications and in the chemical industry. Their excellent resistance to corrosion enables them to withstand a chloride medium, particularly under mechanical stress. This makes them superior to austenitic steel in many cases. The category of austenitic corrosion resistant stainless steel tubing primarily includes materials with higher alloys (e.g. nickel, chrome and molybdenum). They are resistant to different types of corrosion caused by wet chemical influences, and are still able to maintain an austenitic face centred cubic matrix. This creates a range of highly versatile stainless steel. Although one of the main reasons why stainless steel are used is corrosion resistance, they do in fact suffer from certain types of corrosion in some…

  • Comparison Grade 316 vs 316L vs 316Ti Stainless Steel

    Grade 316Ti stainless steel tube has been traditionally specified by German engineers and users with the Werkstoff number 1.4571. Type 316Ti is an improved corrosion resistant Chrome-Nickel steel alloy with high content of Molybdenum and some Titanium. It is not a typical free machining grade and therefore not recommended for difficult high speed machining process 316Ti grade is essentially a standard carbon 316 type with titanium stabilisation and is similar in principle to the titanium stabilisation of the 304 (1.4301) type to produce 321 (1.4541). The addition of titanium is made to reduce the risk of intergranular corrosion (IC) following heating in the temperature range 425-815 °C. Intergranular corrosion When austenitic stainless steel are subject to prolonged heating in the temperature range 425-815 °C, the carbon in the steel diffuses to the grain boundaries and precipitates chromium carbide. This removes chromium from the solid solution and leaves a lower chromium content adjacent to the grain boundaries. Steel in this condition are termed ‘sensitised’. The grain boundaries become prone to preferential atack on subsequent exposure to…

  • Ferritic Stainless Steel Tubes Ferrite Stainless Steel

    Austenitic | Martensitic | Ferritic | Duplex | Super Duplex | Superaustenitic | Superferritic | Precipitation HardeningFerritic Stainless Steel Tubes, in principle, ferrite at all temperatures. This is achieved by a low content of austenitic forming elements, mainly nickel, and a high content of ferrite forming elements, mainly chromium. Ferritic types, such as 4003 and 4016, are mainly used for household utensils, catering equipment and other purposes where corrosion conditions are not particularly demanding. Steel with high chromium content, such as 4762 with 24% chromium, are used at high temperature where their resistance to sulphurous flue gages is an advantage. However, the risk of 475 °C embrittlement and precipitation of brittle sigma phase in high-chromium steel must always be taken into consideration. Ferritic stainless steel, such as 4521 with extremely low carbon and nitrogen contents, find greatest use where there is a risk of stress-corrosion cracking. Ferritic stainless steel have slightly higher yield strength (Rp 0.2) than austenitic steels, but they have less elongation at fracture. Another characteristic that distinguishes ferritic steel from austenitic material is that ferritic steel have much…

  • Austenitic Stainless Steel

    Austenitic | Martensitic | Ferritic | Duplex | Super Duplex | Superaustenitic | Superferritic | Precipitation Hardening Austenitic Stainless steel is dominant in the market. The group includes the very common AISI 304 and AISI 316 steel, but also the higher alloyed AISI 310S and ASTM N08904 / 904L Austenitic steel are characterised by their high content of austenite-formers, especially nickel. They are also alloyed with chromium, molybdenum and sometimes with copper, titanium, niobium and nitrogen. Alloying with nitrogen raises the yield strength of the steels. Austenitic stainless steel have a very wide range of applications, e.g. in the chemical industry and the food processing industry. The molybdenum-free steel also have very good high-temperature properties and are therefore used in furnaces and heat exchangers. Their good impact strength at low temperatures is often exploited in apparatus such as vessels for cryogenic liquids. Austenitic stainless steel cannot be hardened by heat treatment. They are normally supplied in the quenching–annealing state, which means that they are soft and highly formable. Cold working increases their hardness and strength. Certain steel grades are therefore supplied…

  • Cleaning of 304 Stainless Steel

    Despite their corrosion resistance, stainless steel tubes need care in fabrication and use to maintain their surface appearance even under normal conditions of service. In welding, inert gas processes are used. Scale or slag that forms from welding processes is removed with a stainless steel wire brush. Normal carbon steel wire brushes will leave carbon steel particles in the surface which will eventually produce surface rusting. For more severe applications, welded areas should be treated with a descaling solution such as a mixture of nitric acid and hydrofluoric acid, and these should be subsequently washed off. For material exposed inland, light industrial, or milder service, minimum maintenance is required. Only sheltered areas need occasional washing with a stream of pressurized water. In heavy industrial areas, frequent washing is advisable to remove dirt deposits which might eventually cause corrosion and impair the surface appearance of the stainless steel. Stubborn spots and deposits like burned-on food can be removed by scrubbing with a non-abrasive cleaner and fiber brush, a sponge,…

  • Heat Treatment of 304 Stainless Steel

    According to ASTM A213,the austenitic stainless steel are heat treated to remove the effects of cold forming or to dissolve precipitated chromium carbides. The surest heat treatment to accomplish both requirements is the solution anneal which is conducted in the 1850°F to 2050°F range (1010°C to 1121°C). Cooling from the anneal temperature should be at sufficiently high rates through 1500-800°F (816°C – 427°C) to avoid reprecipitation of chromium carbides. These material cannot be hardened by heat treatment.Heat | Metal Glossary | Metals Definitions | Heat Treatment of Metals | Stress Relieving | Passivation | Annealing | Quenching | Tempering | Straightening | Heat Treatment of Steel | Heat Treating Definition | Heat Treating Stainless Steel | Technic of Metals Heat Treatment | Elements in Annealed State | Bright Anneaing | ASTM A380 | ASTM A967 | EN 2516 | 304 | 304L | 304H | 321 | 316L | 317L | 309S | 310S | 347 | 410 | 410S | 430 | Heat Transfer | Forms | Effects | Conduction | Convection | Radiation | Heat ExchangerGeneral PropertiesChemical CompositionResistance to CorrosionPhysical PropertiesMechanical PropertiesWeldingHeat TreatmentCleaning304/304L/304LN/304H Tubing and Pipe

  • 304 Welding

    The austenitic stainless steel tubing are considered to be the most weldable of the high-alloy steel and can be welded by all fusion and resistance welding processes. The Alloys 304 and 304L are typical of the austenitic stainless steel. Two important considerations in producing weld joints in the austenitic stainless steel are: preservation of corrosion resistance, and avoidance of cracking. A temperature gradient is produced in the material being welded which ranges from above the melting temperature in the molten pool to ambient temperature at some distance from the weld. The higher the carbon level of the material being welded, the greater the likelihood that the welding thermal cycle will result in the chromium carbide precipitation which is detrimental to corrosion resistance. To provide material at the best level of corrosion resistance, low carbon material (Alloy 304L) should be used for material put in service in the welded condition. Alternately, full annealing dissolves the chromium carbide and restores a high level of corrosion resistance to the standard carbon content materials. Weld metal with…

  • 304 Resistance To Corrosion Properties

    General CorrosionThe Alloys 304, 304L, and 304H austenitic stainless steel provide useful resistance to corrosion on a wide range of moderately oxidizing to moderately reducing environments. The alloys are used widely in equipment and utensils for processing and handling of food, beverages, and dairy products. Heat exchangers, piping, tanks, and other process equipment in contact with fresh water also utilize these alloys. Alloys 304, 304L, and 304H are also resistant to moderately aggressive organic acids such as acetic acid and reducing acids such as phosphoric acid. The 9 to 11 percent of nickel contained by these 18-8 alloys assists in providing resistance to moderately reducing environments. The more highly reducing environments such as boiling dilute hydrochloric acid and sulfuric acids are shown to be too aggressive for these materials. Boiling 50 percent caustic is likewise too aggressive. In some cases, the low carbon Alloy 304L may show a lower corrosion rate than the higher carbon Alloy 304.
