Weston Stainless in Midland, UK, is a reputable source of quality stainless steel products that focus on industrial welding consumables. Of its high-end products, AWS Class ER317L SAW (Submerged Arc Welding) wire and flux are specifically created for high corrosion resistance, especially in acidic and chloride environments. This filler wire, produced from low-carbon austenitic stainless steel, comes in wire form and is applied with flux to produce deep penetration and high-strength welds. The high molybdenum composition increases resistance to crevice and pitting corrosion, making it perfect for demanding industrial applications.
AWS Class ER317L SAW wire consists of about 18-20% chromium, 13-15% nickel, 3-4% molybdenum, and low carbon content, giving it improved corrosion resistance. Its mechanical properties consist of tensile strength of approximately 550-600 MPa, yield strength of approximately 300 MPa, and elongation of 35%. Its physical properties consist of a density of 7.9 g/cm³ and a melting range of 1350-1400°C. The flux utilized with it ensures stable arc behavior, enhanced slag removal, and smooth weld bead formation with less spatter.
