ASTM Seamless Stainless Steel Tubing 304 , 316 Ss Seamless Tubing High Pressure
304, 316 and 316L stainless steel formulas are austenitic, a term classifying the steel’s crystalline structure. This structure is achieved via heat treatment at very high temperatures followed by quenching—a rapid cooling process locking the structural characteristics in place. Austenitic formulas are stronger than martensitic or ferritic steels. Ferritic steels are magnetic, have a low carbon content and are less corrosion-resistant.
