Product Description

347 Stainless Steel Bar

347 Stainless Steel Bar

347 stainless steel bar is an austenitic stainless steel offering an excellent resistance to inter-granular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500O F. 347 stainless steel bar alloyed with columbium-tantalum (referred to as niobium) allows good mechanical properties at high temperatures.


Applications of 347 Stainless Steel Bar:

•High temperature gaskets
•Rocket engine parts
•Expansion joints
•Aircraft collector rings
•Exhaust manifolds
•Chemical production equipment
