ASTM A312 TP347H Stainless Steel Seamless Pipe For High Temperature

What is material TP347H?

ASTM A312 Gr Tp347h is an austenitic stainless steel. It has chromium and nickel content which give it the corrosion resistant properties. For extra toughness, the A312 347h material has higher carbon content.

We are the professional exporter and supplier of ASTM A312 TP347H Seamless Stainless Steel Pipe,SA 312 TP347H pipe,ASTM A312 TP347 Seamless Stainless Steel Pipe.


A312 TP347H pipe is mainly used where corrosion resistance and sustained operations at temperatures between 800°F and 1500°F (427°C ~ 816°C) is of the utmost importance. It is also a superior grade for use on heavy welded objects, which cannot be re-annealed.

As a higher grade from AISI 321H, the intergranular corrosion of 347H is achieved through the use of niobium (Nb) as a stabilizing element to maximize this feature. SS 347 has a good mechanical properties welding performance, excellent resistance to intergranular corrosion.

Basic features of SS347H


(1) High high temperature strength and high temperature plasticity
(2) Excellent oxidation resistance and corrosion resistance
(3) Good structural stability
(4) Uniform chemical composition
(5) Good processing and welding performance
(6) High dimensional accuracy and surface quality
