AISI 304 Stainless Steel (UNS S30400) Wiki. AISI 304 stainless steel (UNS S30400) is the most widely used austenitic chromium-nickel stainless steel. Its nominal composition is 18% chromium and 8% nickel, so it is also called 18/8 stainless steel. It is essentially non-magnetic when annealed and may become slightly magnetic when cold-worked.
Research highlights. A good combination of mechanical properties of AISI 420 steel can be achieved through the optimization of heat treatment process (austenitizing and tempering temperature and time). The corrosion properties were shown not to be affected in this type of steel when optimizing the heat treatment conditions. The maximum hardness …
