A213 TP347H S34709 Stainless Steel Pipe Tube For Pyrochemical Process
Sch80S Stainless Steel Pipe Tube EN 1.4841 Used in Apparatus Engineering
Product Introduction
Alloy 347 is a stable austenitic chromium steel containing columbium, which eliminates carbide precipitation and prevents intergranular corrosion. Stabilized by chromium and tantalum additions, Alloy 347 offers superior creep and stress rupture properties compared to alloys 304 and 304L. It is particularly suitable for applications concerned with sensitization and intergranular corrosion. The niobium addition provides excellent corrosion resistance, surpassing even 321 alloy. 347H is the high-carbon variant with enhanced high-temperature and creep properties.
Applications
Pyrochemical process
Heat exchange tube
High-temperature steam plant
High pressure steam pipe
Radiant superheater
Boiler tube
Heavy duty exhaust system
General refinery piping
