Our company stocks 347 347H heat resistant stainless steel coil in thicknesses from 0.3mm to 20mm.

General Properties
Alloy 347 (S34700) is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500° F (427 to 816° C). Alloy 347 is stabilized by the addition of columbium and tantalum.

Alloy 347 stainless steel is also advantageous for high temperature service because of its good mechanical properties. Alloy 347 stainless steel offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion are concerns.
