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.
Key Features: Excellent atmospheric corrosion resistance, superior oxidation resistance, widely used as standard food grade stainless steel in the food industry.
