UNS S30400 , DIN 1.4301, EN X5CrNi1911, BS304S31, JIS SUS304
Austenitic Cr-Ni stainless steel. Better corrosion resistance than Type 302. High ductility, excellent drawing, forming, and spinning properties. Essentially non-magnetic, becomes slightly magnetic when cold worked. Low carbon content means less carbide precipitation in the heat-affected zone during welding and a lower susceptibility to inter granular corrosion.
