Product Description
ASTM A312 TP304H Stainless Steel Seamless Pipe SCH80 High Temperature Boiler Tube
Product Introduction
ASTM A312 TP304H is a high carbon variant of the 304 grade, with a controlled carbon range of 0.04% to 0.10%. The higher carbon content delivers improved creep and rupture strength at elevated temperatures, making it a workhorse material for high-temperature steam and process service.
TP304H pipe is typically supplied solution annealed with a grain size of ASTM 7 or coarser to meet the elevated temperature design requirements of the ASME and ASTM specifications.
