Superchromax RS is a rutile coated high-efficiency MMA electrode, ~160% recovery, for surfacing and joining ferritic to austenitic steels, dissimilar joining and difficult-to-weld steels. Also suitable for buffer layers when hardfacing. Stainless, fully austenitic chromium-nickel-manganese weld metal, small amounts of delta-ferrite are possible. The weld metal is highly crack-resistant and non-scaling up to +850 °C. The hardness of all-weld metal is ~180 HB, which work-hardens to ~450 HB under impact load. Highest operating temperature for dissimilar steel joints is +300 °C. In case of higher temperatures, use SUPRANEL 600 electrodes.
