Product Specification

• Ideal for large composite dies and extensive repairs.
• Maintains hardness and wear resistance at elevated temperatures.
• Hardness adjustable via post-weld heat treatment or tempering.
• High resistance to thermal shock.

• Low carbon, Cr-Mo-V alloy similar to H12.
• Designed for hot-working applications with superior wear resistance.

• Keep electrodes completely dry.
• Remove fatigued/work-hardened material by gouging or grinding.
• Preheat base metal 300–550 °C (depending on die size/thickness).
• Use stringer beads, short arc; weave ≤3× electrode dia.
• Peen weld deposit after welding.

• Control hardness with post-weld heat treatment/tempering.
