Low heat input electrode for welding of AISI 430 and equivalent 17% chromium steels. Martensitic Stainless Steel Deposits withstand Cavitation Erosion.
LoTherme-430 is ideally suited for Welding of stainless steel AISI 430 and equivalent 17% chromium steels. For overlay on carbon steel, low alloy steels, and chromium steels. It is appropriate electrode, where the service conditions require good resistance to corrosion, cavitation and heat up to 550°C. Typical applications include surfacing of valves, impellers, hydro-turbine pelton wheel, and valve seats.
Keeping the electrodes dry. For best results, re-dry the electrodes at 250-300°C for one hour before use. Clean the weld are thoroughly free of any foreign matter. Use low current, short arc and stringer beads.
