TP 347H

Short Description:

TP347H Stainless steel seamless pipe is different with TP347 stainless steel seamless pipe. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements. Grade TP347HFG stainless steel seamless pipe shall be cold finished. TP347H stainless steel seamless pipe shall be reheated to the specified solution treatment temperature for the required time before quenching.   Specification Size OD: 6.0 ~ 40...
