WR-Cord 309 Mo is a rutile coated, AC/DC electrode operating in all positions. The weld metal contains 25% Cr, 12% Ni and 2.5% Mo and is resistant to oxidation up to 1050°C. The addition of Molybdenum improves its tensile strength at elevated temperatures. The weld metal has very good resistance to chemical corrosion and heat.
WR-Cord 309 Mo is used for joining stainless steel of grade 316 to Carbon and low alloy steels, welding of AISI grade 309Mo, building up worn out parts subject to corrosion and wear.
