What is A312 TP316?

316 pipe to A312/SA312 for general corrosive service. Strength guide: min tensile ~515 MPa (75 ksi), min yield ~205 MPa (30 ksi) typical — confirm PO.

Typical applications

  • Chemical and petrochemical process piping
  • Coastal / marine-adjacent utilities (within 316 limits)
  • Pharma and food where Mo-bearing stainless is specified
  • Pulp & paper and chloride-bearing waters (screening still required)

Selection guidance

Default Mo-bearing choice for chloride service below duplex. Prefer 316L for heavy welds; 316H / 316Ti for elevated temp / stabilised needs.
