Grade 420 Stainless Steel Sheet
400 SERIES 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.
Type 420 is a martensitic stainless steel that provides good
corrosion resistance similar to 410 plus increased strength and
hardness. It is magnetic in both the annealed and hardened
conditions. Maximum corrosion resistance is attained only in the
fully hardened condition. It is never used in the annealed
condition.
