ASTM A182 F316 / F316L / F316H Specification 

ASTM A182 F316 / F316L / F316H Specification 

ASTM A182 F316, F316L, and F316H specification covers austenitic stainless steel forgings for pressure-containing parts and high-temperature service.
These grades are molybdenum-bearing stainless steels offering excellent corrosion resistance, particularly against chlorides, acids, and aggressive chemical environments.

This page provides access to the ASTM A182 F316 / F316L / F316H specification PDF, including chemical composition, mechanical properties, heat treatment requirements, and typical industrial applications for forged stainless steel components.

Overview of ASTM A182 F316 / F316L / F316H Grades

ASTM A182 F316 series stainless steels are chromium-nickel-molybdenum alloys designed for enhanced corrosion resistance compared to Type 304.

  • F316: Standard grade with balanced strength and corrosion resistance

  • F316L: Low carbon version with improved resistance to intergranular corrosion after welding

  • F316H: High carbon version with increased high-temperature strength

These grades are widely used for forged flanges, fittings, valves, and pressure components.

Chemical Composition & Mechanical Properties

The ASTM A182 F316 / F316L / F316H specification PDF includes detailed requirements for:

  • Chemical composition limits for Cr, Ni, Mo, and carbon content

  • Mechanical properties such as tensile strength, yield strength, and elongation

  • Heat treatment and solution annealing requirements

  • Testing, inspection, and certification procedures

These specifications ensure reliable performance of stainless steel forgings under pressure and corrosive service conditions.

Typical Applications of ASTM A182 F316 Series Forgings

ASTM A182 F316, F316L, and F316H forgings are commonly used in:

  • Chemical processing and petrochemical equipment

  • Oil and gas pipelines and pressure systems

  • Marine and offshore applications

  • Food processing and pharmaceutical industries

  • High-temperature piping and pressure vessels

The addition of molybdenum provides superior resistance to pitting and crevice corrosion.
