ASTM A312 TP347H Pipe

Description of alloy 347H

The alloy is austenitic chromium stainless steel. It has Cr 17-20%, Ni 9-13%, C 0.04-0.08%, MN 0.5-2%, S 0.30%, Si 0.75%, etc. This alloy is used for heavy welded equipment. It has corrosion resistance properties the same as alloy 304.

Features of the pipe

The feature of the pipe is greatly responsible for the making of the pipes. Our pipes have an excellent quality of highly tensile strength, rugged construction, anti-corrosive, flexibility, rigidity, durability, etc. It has good dimensional accuracy, superb surface finish, and corrosion resistance ability.
