Description
ASTM A312 TP347H Stainless Steel Seamless Pipe SCH80 High Temperature Power Plant
Product Introduction

ASTM A312 TP347H is the high carbon niobium stabilized grade, with a carbon range of 0.04% to 0.10%. It offers higher creep and stress rupture strength than standard TP347, making it ideal for the most demanding elevated temperature service.

Supplied solution annealed with a controlled coarse grain size, TP347H pipe is a proven material for superheater and reheater tubing and high temperature steam piping in power generation plants.
