• 321 VS 304 VS 304L Difference Between 321 and 304 304L

    TP321 TP321H stainless steel is basically from 304 stainless steel. They different by a very very small addition of Titanium. The real difference is their carbon content. The higher the carbon content the greater the yield strength. 321 stainless steel has advantages in a high temperature environment due to its excellent mechanical properties. Compared with 304 alloy, 321 stainless steel has better ductility and resistance to stress fracture. In addition, 304L can also be used for anti-sensitization and intergranular corrosion. Grade TP304L is more readily available in most product forms, and so is generally used in preference to 321 if the requirement is simply for resistance to intergranular corrosion after welding. However 304L Stainless Steel Tubes has lower hot strength than 321 stainless steel tube and so is not the best choice if the requirement is resistance to an operating environment over about 500°C. However, 321 is a much better…

  • 304 vs TP304 Difference between 304 and TP304 in China

    TP304 is equivalent to 06Cr19Ni10 (new GB standard 304), 304 is equivalent to 0Cr18Ni9(old GB standard 304). In terms of price, TP304 is also about USD 65 more expensive than 304 (per metric tons) What is the element content? The main difference between 304 and TP304 is its chromium content. The chromium content of TP304 is one higher, reaching more than 18, so its corrosion resistance and price are slightly higher than that of GB 304. Therefore, TP304 is more expensive than 304 in price, and the ingredients are as follows: Grade – C Mn Si P S Cr Mo Ni N TP304 min.max. -0.08 -2.0 -1.00 -0.045 -0.030 18.0-20.0 – 8.0-11.0 – 304 min.max. -0.08 -2.0 -1.00 -0.040 -0.015 17.00-19.5 – 8.0-10.5 – General PropertiesChemical CompositionResistance to CorrosionHeat ResistancePhysical PropertiesMechanical PropertiesWeldingHeat TreatmentCleaning304/304L/304LN/304H Tubing and PipeStainless Steel ” L” “H” GradeDifference Between 304H and 347HDifference Between 304 304L and 321304…

  • Advantages of duplex stainless steel

    Due to the high strength of Duplex steel, it is usually possible to save material, such as reducing the wall thickness of the pipe. Take the use of SAF2205 and SAF2507 as an example. SAF2205 is suitable for use in chlorine-containing environments. The material is suitable for oil refining or other process media mixed with chloride. SAF2205 is especially suitable for heat exchangers that use chlorine-containing aqueous solutions or brackish water as the cooling medium. The material is also suitable for diluted sulfuric acid solutions and pure organic acids and their mixtures. Such as: oil pipes in the oil and natural gas industry: crude oil desalination in oil refineries, sulfur-containing gas purification, wastewater treatment equipment; cooling systems that use brackish water or chlorinated solutions. Compared with austenitic stainless steel 1) The yield strength is more than twice that of ordinary austenitic stainless steel, and it has sufficient plastic toughness for…

  • What is Stainless Steel?

    In metallurgy, stainless steel, also known as inox steel or inox, is defined as a steel alloy with a minimum of 10.5 or 11% chromium content by mass. Stainless steel does not stain, corrode, or rust as easily as ordinary steel (it stainsless, but it is not stain-proof). It is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry. There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime. Common uses of stainless steel are cutlery and watch cases and bands. Stainless steel differs from carbon steel by the amount of chromium present. Carbon steel rusts when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide. Stainless steel have sufficient amounts of chromium present so that a passive film…
