Alloy information to know-
Stainless steel 317L alloy is the molybdenum bearing low carbon austenitic stainless steel with the increased addition of alloying elements like molybdenum, nickel, and chromium. This is for the purpose of offering very good corrosion resistance ability as well as increased resistance to the chemical attacks for the acids like tartaric, sulfurous, acetic, citric and formic. Because of the low carbon content, this alloy is providing the sensitization resistance when welded and high creep and stress to rupture and high tensile strength at the elevated temperature. This alloy is non-magnetic in nature in an annealed condition but might become a little bit magnetic when welded.
Production of the buttweld fittings-
We are the customer-focused manufacturer and during the time of product development at our highly operational industry, we are making effective use of the superior quality of raw materials only.
