产品说明
ATI 316™ (UNS S31600), ATI 316L™ (S31603), ATI 317™ (S31700) and ATI 317L™ (S31703) alloys 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 ATI 304. These alloys also offer higher creep, stress-to-rupture and tensile strength at elevated temperature. ATI 317™ and ATI 317L™ alloys containing 3 to 4% molybdenum are preferred to ATI 316™ or ATI 316L™ alloys which contain 2 to 3% molybdenum in applications requiring enhanced pitting and general corrosion resistance. ATI 316LM™ alloy (W.Nr. 1.4404), a 2.5% minimum Mo version of ATI 316L™ stainless steel, is available only by special order.

Austenitic stainless steels with higher molybdenum or molybdenum plus nitrogen content which provide even greater resistance to pitting, crevice corrosion and general corrosion are also available in flat-rolled products. These include ATI 316LN™ (UNS S31653), ATI 317LX™ (UNS S31725, 4-5% Mo), ATI 317LXN™ (S31726, 4-5% Mo and 0.1-0.2% N), and AL-6XN® (N08367, 6-7% Mo and 0.18-0.25% N) alloys. Properties of these alloys are described in separate ATI technical data publications available.

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