Austenite 316L Stainless Steel

 

316L(UNS S31603)

General Properties
Alloys 316 (UNS S31600), 316L (S31603), and 317L (S31703) are molybdenum-bearing austenitic stainless steels which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Alloy 304. These alloys also offer higher creep, stress-to-rupture, and tensile strength at elevated temperature. Alloy 317L containing 3 to 4% molybdenum is preferred to Alloys 316 or 316L which contain 2 to 3% molybdenum in applications requiring enhanced pitting and general corrosion resistance.

In addition to excellent corrosion resistance and strength properties, the Alloys 316, 316L, and 317L Cr-Ni-Mo alloys also provide the excellent fabricability and formability which are typical of the austenitic stainless steels.

Product form: sheet, pipe, bar, coil. Size can be offered according to customers' requirement.

Composition:
Chemical composition as represented by ASTM A240 and ASME SA-240 specifications are indicated in the table below.
