• Vanadium
• Chromium
• Carbon

• Clean & grind surface, remove rust/paint.
• AC/DC (reverse polarity on DC).
• Use low current, stringer beads, chip & peen between passes.
• Preheat hardenable steels: 250–400 °C; interpass >300 °C.
• Double temper at 550 °C × 1 hr × 2 for better hot wear life.

• Cutting, piercing & shaving tools.
• Hot working punches/dies.
• Extrusion moulds & dies.
