Description:
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.
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.
