ASTM A268 TP 410 ASME SA268 TP 410 Stainless Steel Seamless Tubing and Welded Pipes
ASTM A268 ASME SA 268 TP410 S41000 is a martensitic stainless steel with high mechanical properties and is ferromagnetic in the annealed or hardened condition. 410 contains the minimum amount of chromium to impart stainless steel properties. 410 resists oxidation and scaling up to 1200 degF. Hardness is one of 410’s best features; It resists abrasion and wear better than most 300 series stainless steel. Grade 410 is often supplied in the hardened, but still machinable condition, for applications where high strength and moderate heat and corrosion resistance are required
410 Stainless Steel is the basic, general purpose, hardenable martensitic stainless steel. It is used for highly stressed parts with good corrosion resistance and strength. Alloy 410 resists corrosion in mild atmospheres, steam, and many mild chemical environments. The alloy can be heat treated to obtain high strength with good ductility.This alloy is used where strength, hardness, and/or wear resistance must be combined with corrosion resistance.
410 Stainless Steel is a hardenable, straight-chromium stainless steel which combines the superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steel. Oil quenching this alloy from temperatures between 1800°F to 1950°F (982-1066°C) produces the highest strength and/or wear resistance as well as corrosion resistance. A range of as-quenched hardnesses is achieved by varying the carbon level from .15% maximum in Alloy 410.
Martensitic stainless steel are optimised for high hardness, and other properties are to some degree compromised. Fabrication must be by methods that allow for poor weldability and usually the need for a final heat treatment. Corrosion resistance of the martensitic is lower than that of the common austenitic grades, and their useful operating temperature range is limited by their loss of ductility at sub-zero temperatures and loss strength by over-tempering at elevated temperatures.

410 Stainless Steel Physical Properties
Typical physical properties for annealed grade 410 stainless steels are given in table 6.

410 Stainless Steel Corrosion Resistance
410 resists dry atmosphere, fresh water, mild alkalies and acids, food, steam and hot gases. Must be hardened for maximum heat and corrosion resistance. Performance is best with a smooth surface finish. Less corrosion resistant than the austenitic grades and also less than 17% chromium ferritic alloys such as Grade 430.
410 Stainless Steel Heat Resistance
Good resistance to scaling up to approximately 650°C, but generally not recommended for use in temperatures between 400 and 580°C, because of the reduction in mechanical properties.
410 Stainless Steel Heat Treatment
410 Stainless Steel Annealing
Full anneal – 815-900°C, slow furnace cool to 600°C and then air cool.
Process Anneal – 650-760°C and air cool.
410 Stainless Steel Hardening
Heat to 925-1010°C, followed by quenching in oil or air. Oil quenching is necessary for heavy sections. Temper, generally within the range 200-400°C, to obtain a wide variety of hardness values and mechanical properties as indicated in the accompanying table.
The tempering range 400-580°C should generally be avoided.
410 Stainless Steel Welding
Readily welded by all standard methods, but a pre-heat of 150-260°C and post-weld annealing treatment is required to reduce the possibility of cracking. Use Grade 410 welding rod if post hardening and tempering is involved. If parts are to be used in the “as welded” condition, a ductile joint can be achieved by using Grade 309 filler rod.
AS 1554.6 pre-qualifies welding of 410 with Grade 309 rods or electrodes.
410 Stainless Steel Machining
In the annealed or highly tempered conditions grade 410 is relatively easily machined, but if hardened to above 30HRC machining becomes more difficult. Free machining grade 416 is a very readily machined alternative.
