description
347 Stainless Steel Alloy Description:
347 alloys are stabilized stainless steels which offer as their 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). 347 alloys are stabilized by the addition of columbium.
application
