316H
Data verified316H is the high-carbon variant of 316, specified where creep strength is required in high-temperature pressure equipment that also sees corrosive process media. The carbon window 0.04–0.10% guarantees elevated-temperature strength values in the design codes.

Applications & Processing
Applications: High-temperature chemical and petrochemical pressure parts, superheater components, refinery piping.
Processing: Weldable with 316-type consumables; not intended for ambient-temperature corrosive welded service where 316L is the better choice.
