316 1.4401 316L 1.4404 General Properties

Alloys 316 (UNS S31600), 316L (S31603), and 317L (S31703) are molybdenum-bearing austenitic stainless steel pipe which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steel tube 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 steel pipe.
