Material Description
About 304/304L Stainless Steel
AISI 304 stainless steel (UNS S30400) is the most widely used
stainless steel, containing 18-20% Cr and 8-10.5% Ni, also known as
18-8 stainless steel. SS 304 is non-magnetic under annealing
conditions but may become weakly magnetic after cold working
processes. Type 304 offers excellent resistance to atmospheric
corrosion and oxidation, with high nickel-chromium alloy content
providing superior corrosion resistance, making it the standard
food grade stainless steel in the food industry.
