What material is 347 stainless steel
347 stainless steel
Grade 347 stainless steel is a stable alloy because it contains columbium + tantalum components. 347 stainless steel is ideal for long service life at high temperatures (800-1500ºF) and is resistant to intergranular corrosion in the chrome carbide precipitation range. High creep and stress fracture characteristics are part of its excellent mechanical properties.
