Product Specification
• As-welded hardness: 60–64 HRC.
• Oil tempering at 550 °C improves hot strength.
• Good weldability in flat, horizontal & vertical-up.
• Primary Chromium Carbides.
• Secondary carbides -Tungsten, Molybdenum & Vanadium Carbides.
• Clean & grind surface, remove rust/paint.
• AC/DC (reverse polarity on DC).
• Use low current, stringer beads, chip & peen between passes.
• If thebase metal is hardenable steel, preheat it to 250–400° C depending onbase metal composition
• Keep interpass temprature greater than 300° C
• Cutting, piercing & shaving tools.
• Hot working punches/dies.
• Extrusion moulds & dies.
• Shear blades, milling & cutting tools.
• Ingot lifting tongs, rolling mill guides.
• Woodworking tools, stamping die cutting edges.
