• For welding 18% chromium – 12% nickel – 21⁄2% molybdenum austenitic stainless steels such as 316 and 317 but with a low ferrite (i.e. FN2) it can also be used for welding 304/304L to 316/316L stainless steels in cryogenic service at temperatures down to -452 F
• The maximum carbon content of less than 0.03% preserves the intergranular corrosion resistant properties of the weld deposit and weld zone, yielding x-ray quality welds
• The 21⁄2% molybdenum content of 316L gives the weld deposit excellent corrosion resistance at elevated temperatures against “pitting” that may be caused by sulfuric, phosphoric and acetic acids
• Common applications include equipment that manufacturers rayon, dye, paper, ink, rubber, bleach, photographic chemicals and on the sealing faces of valves and fittings for acid, gas, water and steam equipment
