Fully Annealed 1 inch Ferritic Stainless Steel Tubing ASTM A268 TP410 410S 409 439​



The 400 series of stainless steels have a higher carboncontent, giving it a martensitic crystalline structurethat provides the end product with high-strength andhigh-wear resistance. The 400 series steels tend to beused in agricultural equipment, gas turbine exhaustsilencers, hardware, motor shafts, and more.

The 400 series group of stainless steels has an 11 percent chromium and 1-percent manganese increase, above the 300 series group. The 400 series is susceptible to rust and corrosion under some conditions. Heat-treating will harden the 400 series. The 400 series of stainless steels have higher carbon content, giving it a martensitic crystalline structure. This provides high strength and high wear resistance. Martensitic stainless steels aren’t as corrosion resistant as the austenitic types.

The alloy contains 11.5% chromium which provides good resistance to atmospheric corrosion. However, corrosion resistance is limited unless the alloy is further enhanced by processes including hardening, tempering and polishing. Type 410 displays excellent hardness after heat treatment and the material can be used in the fabrication of highly stressed parts. Weldability of the alloy is generally poor.


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.

- Harding by heat treatment
- High hardness with good ductility
- Good corrosion resistance capability
- Good wear corrosion resistance
- High cold-deformation property


Available Tube Product Forms:




Typical Applications:


Used for parts requiring a combination of good strength and toughness, plus reasonable corrosion resistance. Typical applications are: Bolts, Bushings, Fasteners, Gas Turbine Parts, Mine Equipment, Pump Parts, Petrochemical Equipment, Steam Turbine Parts, Studs, Valve Parts etc.

Material magnetic in all conditions.


410 - UNS S41000:

AISI Type 410 is a martensitic stainless steel that provides high strength and hardness with moderate corrosion resistance. A wide range of properties can be developed with different heat treatments, with ultimate tensile strengths ranging from 500 to 1400 MPa. It is magnetic in both the annealed and hardened conditions. High carbon content results in the formation of chromium carbide compounds, providing excellent wear resistance and edge retention when hardened. Additionally, this grade provides excellent high temperature oxidation and scaling resistance, yet is economical due to the low alloy content. Thermal conductivity is improved and thermal expansion reduced relative to austentic stainless grades.

Grade 410S is a ferritic stainless steel that is a lowcarbon variation of ferritic type 410 stainless steel. Due to the lower level of carbon and the addition oftitanium and/or columbium, this alloy minimizesaustenite formation at higher temperatures. This alsoprevents hardening and prevents cracking whenwelding.
