317L Stainless Steel Plate
Standard: ASTM A240 / ASME SA240
Thickness: 0.3-200mm
Length: 1000-6000mm
Width: 1000-2000mm
317L Stainless Steel Plate contains molybdenum and has enhanced resistance to pitting and crevice corrosion in the presence of chlorides and sulfuric acid, acidic chlorine and phosphoric acid compared to the 304 basic chromium-nickel alloy. SS 317L Plate is a low carbon grade of 317 with only 0.03% carbon, making it more resistant to sensitivity during welding or heat treatment. Alloy 317L Plate also has higher creep strength, rupture stress and tensile strength. Contact us for more information and free quotes!
