GRADE
Grade 316L (UNS S31603, EN 1.4404) is molybdenum-bearing austenitic stainless steels, which is more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Grade 304. 316l Stainless Steel Sheet The low carbon chemistry of 316L combined with an addition of nitrogen enables 316L to meet the mechanical properties of 316.
Grade 316L is often utilized in process streams containing chlorides or halides. The addition of molybdenum improves general corrosion and chloride pitting resistance. It also o"ers higher creep, stress-to-rupture, and tensile strength at elevated temperatures. 316l Stainless Steel SheetIn addition to excellent corrosion resistance and strength properties, the Grade 316L Cr-Ni-Mo alloys also provide excellent fabricability and formability .
