347 Stainless Steel Round Bars & Angle Bars By yaang.com

by yane Yang Sales Manager

Stainless Steel 347 is a Chromium-Nickel steel that is similar to Type 321 with higher creep strength. It shows great resistance to prolonged heat making it a good choice for applications such as engine or power generation parts. Stainless Steel 347 is also useful for applications requiring omission of the annealing process post-welding.

Applications:

Airplane exhaust stacks
Welded tank cars for chemicals
347 Stainless Steel Angle Bars
Collector rings
Expansion joints
Oil Refineries
Fluid catalytic cracking units (FCC)
Stainless Steel Pipes
Recuperator stainless steel pipe fittings
Especially where temperatures exceed 550°F and resistance to sulfidation is needed
Fired heater stainless steel tubes
Distributor trays and thermowells
Equipment in and around reactors (good resistance to polythionic acid)
Stainless Steel Flanges
