stainless steel pipes and billets

stainless steel pipes are with large diameter and small diameter and the most versatile and most widely used stainless steel.
These properties are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.
