ASTM A333 Grade 9 Seamless Pipe

ASTM A333 Grade 9 Seamless Pipe are applicated for low temperature service.

ASMT A333 Grade 9 seamless pipes

The ASTM A333 Grade 9 steel involved is similar to AISI 4032 low alloy steel. ASTM A333 Grade 9 pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation. ASTM A333 Grade 9 covers seamless and welded steel pipe for low temperature service. The Grade 9 alloy steel involved is similar to AISI 4032 low alloy steel.
