ASTM A312 vs ASTM A358

What is ASTM A312?

ASTM A312 is a specification for seamless and welded austenitic stainless steel pipes that perform well in high temperature and corrosive environments. The common grades for this specification are 304/304L and 316/316L.

What is ASTM A358?

ASTM A358 is a specification for electric-fusion-welded austenitic stainless steel pipe that performs well in high temperature industrial applications.

Industrial Applications

Stainless steel welded pipe is corrosion resistant and this type of material is extremely durable in harsh conditions. This type of pipe is popular in industrial applications in the following industries:

  • Chemical
  • Food and beverage
  • Marine
  • Mining
  • Oil and gas
  • Pharmaceutical
  • Petrochemical
  • Power generation
