What is A312 TP316H?

316H pipe to A312/SA312 for general corrosive service. Strength guide: per SA-312 TP316H — elevated-temperature intent; confirm PO.

Typical applications

  • Hot process piping needing Mo + H-grade carbon
  • Refinery / chemical elevated-temp lines

Selection guidance

Only when the datasheet names 316H. Do not assume dual-cert 316/316L covers H-grade creep service.
