Product Details
Grade 443 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.
Stainless steel 443, which is a kind of ferritic stainless steel,
is now generally used to replace 304. Its rust resistance and
processing performance are comparable to those of 304. It is
currently widely promoted in the fields of electrical appliances,
utensils, kitchen equipment, elevators, and oven making.
