Allegheny Ludlum Type 321 (S32100), 347 (S34700), and 348 (S34800) are stabilized stainless steels which offer as their main advantage an excellent resistance to intergranular corrosion following exposure to tempera- tures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Type 321 is stabilized against chromium carbide formation by the addition of titanium. Types 347 and 348 are stabilized by the addition of columbium and tantalum. Type 348 has restricted cobalt and tantalum content for nuclear applications.

While Types 321, 347 and 348 continue to be employed for prolonged service in the 800 to 1500°F (427 to 816°C) temperature range, Type 304L has supplanted these stabilized grades for applications involving only welding or short time heating.

Types 321, 347 and 348 stainless steels are also advantageous for high temperature service because of their good mechanical properties. Types 321, 347 and 348 stainless steels offer higher creep and stress rupture properties than Type 304 and, particularly, Type 304L which might also be considered for exposures where sensitization and intergranular corrosion are concerns. This results in higher elevated temperature allowable stresses for these stabilized alloys for ASME Boiler and Pressure Vessel Code applications. The Types 321, 347 and 348 alloys have maximum use temperatures of 1500°F (816°C) for code applications like Type 304, whereas T304L is limited to 800°F (426°C).
