M42 | Cobalt High-Speed Steel Wear-Repair Welding Wire
M42 โ Cobalt High-Speed Steel Wear-Repair Welding Wire
A highly alloyed carbon-tungsten-molybdenum-chromium-cobalt system for repairing high-speed steel tools, trimming dies, and heavily worn components.
Typical hardness: Approximately HRC 60
Recommended processes: TIG welding and laser welding
Alloy / standard reference: C-W-Mo-Cr-Co high-speed steel system
Key Features
- Cobalt-alloyed high-speed steel system
- High hardness and excellent wear resistance
- Suitable for precision repair and surface restoration
- Final selection should be confirmed according to the base material, welding process, and service conditions
Typical Applications
- Cutting edges
- Drill bits
- Milling cutters
- High-wear high-speed steel components
Application guidance: Before welding, confirm the base-material grade, type of damage, heat-treatment condition, and subsequent machining requirements. Validate the final welding procedure on a test piece.
The information above is provided as a typical selection reference. Final supply condition, hardness, chemical composition, and welding procedure shall be confirmed by the order and the corresponding batch material certificate.
