1.2606 / H12 | High-Hardness Thermal-Fatigue-Resistant Repair Welding Wire
1.2606 / H12 โ High-Hardness Thermal-Fatigue-Resistant Repair Welding Wire
A tungsten-alloyed hot-work repair material for dies operating under high temperature and high stress where hardness, wear resistance, and thermal-fatigue resistance are required.
Typical hardness: HRC 55 - 58
Recommended processes: TIG welding and laser welding
Alloy / standard reference: EN 1.2606 / X37CrMoW5-1 | Comparable to AISI H12
Key Features
- Tungsten-alloyed system improves thermal-fatigue resistance
- High as-welded hardness and wear resistance
- Suitable for high-temperature, high-stress service
- Supports durable restoration of hot-work surfaces
Typical Applications
- Aluminum, magnesium, and zinc die-casting dies
- Hot-extrusion dies for aluminum and copper alloys
- Hot-forging dies
- Glass-forming molds
Application guidance: Before repair welding, carefully control preheating, deposit thickness, interpass temperature, and post-weld slow cooling.
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.
