Metrode Thermet-22H description: This electrode is designed to match similar high carbon cast alloys originating from Blaw-Knox (Now Duraloy) alloy 22H. The high carbon 28%Cr-50%Ni-5%W matrix provides excellent hot strength and oxidation resistance at typical service temperatures of 950-1250°C. High nickel gives the alloy good resistance to carburisation and under oxidising conditions high chromium provides useful resistance to sulphidation. Applications include highly stressed furnace parts, sintering and calcining muffles, cement kiln components resistant to hot abrasion, radiant tubes and pyrolysis coils.
