AISI 304 stainless steel (UNS S30400) is the most widely used stainless steel, containing 18-20% chromium and 8-10.5% nickel. 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.
