Stainless Steel UNS S31703 Sheet Plate, Stainless Steel Austenitic S31703 Plate, 317L Stainless Steel Plate, ASTM A240 317L Stainless Steel Plate, SS ASTM A240 317L Plate, ASTM A240 317L Steel Plate, Hot Rolled ASTM A240 317L Steel Plate, Cold Rolled ASTM A240 317L Steel Plate.

Stainless Steel UNS S31703 Sheet Plate is made of a low carbon corrosion resistant austenitic chromium-nickel-molybdenum stainless steel. The high levels of these elements assure the UNS S31703 Sheet has superior chloride pitting and general corrosion resistance to the conventional 304/304L and 316/316L grades. The 317L Stainless Steel Plate provides improved resistance relative to 316L in strongly corrosive environments containing sulfurous media, chlorides, and other halides.

 

We have a broad range of Stainless Steel UNS S31703 Sheet Plates that we manufacture, trade supply, as well as export to our customers worldwide. Stainless Steel 317L Sheets are the most demanded products from our range. ASTM A240 317L Stainless Steel Plates has a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50 / 50 mix, although in commercial alloys. SS ASTM A240 317L Plates have roughly twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion, particularly pitting, crevice corrosion and stress corrosion cracking.
