35-39 RC Seamless Stainless Steel Tube ASTM A268 TP410 0.89MM - 3.05MM Wall Thickness
Stainless steel 410 is a basic martensitic grade which contains 11.5% chromium, offering both exceptional wear and corrosion resistance. SS 410 is corrosion resistant to some chemicals, food, mild acids, water, and air. It also proves adequate resistance to nitric acid, concentrated sulfuric acid, dilute acetic acid and naphtha. Elevated mechanical properties and corrosion resistance are achieved with stainless steel 410 when it's hardened and tempered.
410 seamless stainless steel tube is used in applications such as dental and surgical instruments, pipelines, valves and nozzles, automotive parts and more. 410 SS is generally used for applications which involve mild corrosion, high strength, and heat resistance. Please contact Best Stainless for more information about 410 SS, its properties, and its applications.
410 seamless stainless steel tube is a corrosion and heat resistant 12% chromium steel. It is the most widely used of the hardenable stainless steels. Heat treated 410 has mechanical properties comparable to the engineering alloy steel AISI 4130, coupled with the additional benefit of good corrosion resistance. 410 is highly resistant to atmospheric corrosion. Maximum corrosion resistance is obtained by hardening and polishing.
Because 410 is an air hardening steel, it must be given a high preheat, at least 350-400°F before welding, and immediately given a full anneal before the weldment cools. Otherwise the metal will harden, and cracking is likely. Matching composition filler metals are available, AWS E410 covered electrodes and ER410 bare filler wire. Alloy 82 (AWS ERNiCr-3) filler wire has also been used. This nickel alloy is comparatively low strength, and therefore accommodates some of the strain which may otherwise contribute to cracking in the 410 weldment.
Heat uniformly to 1200-1400°F, remove from furnace and air cool. This should result in Brinell hardness about 187. For maximum softness, heat to 1500-1650°F, furnace cool slowly to 1100°F, after which air cooling is permissible. Brinell hardness should be approximately 155. Heat to 1750-1850°F, soak at heat, and quench in oil. Light sections will also harden by air cooling. 410 will harden to some degree when heated 1500°F and over unless slowly cooled to below the critical temperature. Soak at heat at least one hour, longer for large sections, and air cool. Tempering 410 in the range 750-1050°F results in decreased impact toughness and somewhat reduced corrosion resistance.
Martensitic grades are all heat treatable grades. Type 410 stainless can be hardened to range of 35-39 RC. Please contact us to discuss your particular heat treat requirement specifications.

The characteristic orthorhombic martensite microstructure was first observed by German microscopist Adolf Martens around 1890. Martensitic steels are low carbon steels built around the Type 410 composition of iron, 12% chromium, and 0.12% carbon. They may be tempered and hardened. Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle, so few steels are fully hardened.
