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 its high nickel-chromium alloy content providing superior corrosion resistance, making it the standard food grade stainless steel in the food industry.
Variants include ultra-low-carbon 304L, nitrogen-containing 304N, creep-resistant 304H, and higher-carbon type 302. Compared to AISI 304, 316 stainless steel features reduced chromium, increased nickel, and added 2-3% molybdenum for enhanced resistance to chloride-induced pitting and crevice corrosion, making it ideal for marine applications.
