ATI Allegheny Ludlum Stainless Steel Type 348 (UNS S34800)
Categories: Metal; Ferrous Metal; Stainless Steel; T 300 Series Stainless Steel

Material Notes: AL 348 is a stabilized stainless steel which offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800° to 1500°C. The addition of columbium and tantalum stabilize against chromium carbide formation. For nuclear applications AL 348 has restricted cobalt and tantalum content.
