ASTM A778 stainless steel pipe is used in low to moderate temperature applications. The specification is for unannealed, welded stainless steel materials. There are different grades of materials used under this specification.
The ASTM A778-304l is one of the most used materials. It is a low carbon variation of the 18/8 chromium nickel stainless steel. The chromium nickel composition provides better corrosion resistance and strength while the less carbon content provides ductility and better welding properties.
