400 series stainless steel
we can ensure that the steel we source is tailored to the needs of our valued customers.

Series 400 stainless steel

 The 400 series group of stainless steels typically have an 11% chromium and 1% manganese increase, above the 300 series group. 

 This stainless steel series tends to be susceptible to rust and corrosion under some conditions although heat-treating will harden them. 

 The 400 series of stainless steels have a higher carbon content, giving it a martensitic crystalline structure that provides the end product with high-strength and high-wear resistance. 

 The 400 series steels tend to be used in agricultural equipment, gas turbine exhaust silencers, hardware, motor shafts, and more.

Applications of 400 Series Stainless Steel

The 400 series includes both ferritic and martensitic steels.

Ferritic steels: non-hardening steels,  ideal for conditions in elevated temperatures. Typical applications for ferritic stainless steels include petrochemical, automotive exhaust systems, heat exchanges, furnaces, appliances and food equipment to name a few.

Martensitic steels: able to be hardened, ideal for a wide variety of common uses. Martensitic stainless steels are used extensively in cutlery, sport knives and multi-purpose tools.
