WB4212E MMA Electrodes Martensitic Stainless Steel

Medium coated, mild steel core wire, basic electrode with a metal powder addition to the coating. Having exceptional deslag and arc stability, this electrode produces a recovery of  140%. Suitable for the welding of high strength Martensitic stainless steels having better resistance to corrosion, hydro-cavitation, sulphide-induced S.C.C. and good sub-zero toughness compared with standard 12%Cr steels. Developed primary for CA-6NM castings. Additional material grades: – BS3100 425C11, ASTM F6NM-CA6NM, DIN 14351 1.4313 G-X5CrNi 13 4 & AFNOR Z6 CND 1304-M.
