S30403/304 Stainless steel is the most widely used stainless steel, containing 18-20% Cr and 8-10.5%Ni, and also known as 18-8 stainless steel.SS 304 is non-magnetic under annealingconditions, but after cold working (such as stamping,stretching, bending, rolling),. part of theaustenite structure may be converted into martensite and therefore weakly magnetic. TypeSS304 has good resistance to atmospheric corrosion and oxidation.The high nickel-chromium alloy content allows it excellent corrosion resistance and is widely used in the food industry as a standard food grade stainless steel.
Grade 304,304L material could be shaped as coils,plates or sheets,strips,wires,profiles,bars,pipes or tubes,angles,and others as specially required customization.
