316L (UNS S31603) is a chromium-nickel molybdenum austenitic stainless steel developed to provide improved corrosion resistance to 304L in moderately corrosive environments. It is often utilized in process streams containing chlorides or halides. The addition of molybdenum improves general corrosion and chloride pitting resistance. It also provides higher creep, stress-to-rupture and tensile strength at elevated temperatures.

316L resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. It also resists corrosion in polluted marine atmospheres. The alloy has excellent resistance to intergranular corrosion in the as-welded condition. 316/316L has excellent strength and toughness at cryogenic temperatures.

• Food preparation equipment particularly in chloride environments.
• Pharmaceuticals production components.
• Marine architectural and functional applications.
• Medical implants (pins, screws, orthopedic replacements).
• Fasteners and structural components in corrosive environments.

316L is subject to work hardening during deformation. Best results are achieved with slower speeds, heavier feeds, excellent lubrication, and sharp tooling. Recommended hot working temperatures range from 1700 - 2200°F (927 - 1204°C).
