Type 304 Pipe

Type 304 Stainless Steel Pipe
Seamless and Welded

Type 304 is the basic low carbon “18-8” chromium-nickel stainless steel.  It offers excellent mechanical properties for both room and high temperature service, and has excellent resistance to corrosion.  It is made by the seamless or automatic welding process in which no addition of filler metal is employed in the welding operation.  It is clean and free from scale.Type 304 is available in an extra low carbon grade, designated 304L.  This grade is designed to minimize the danger of intergranular corrosion where welded fabrication is used and where subsequent heat treating is not practical.

Applications — It is used in high temperature and general corrosion service conditions.  It is used in general hydraulic and pressure services where atmosphericand general corrosive conditions are encountered.  It is not intended for salt water systems or use in high pressure main steam lines.
