T42 Steels Tool
Mascot Steel Centre is proud and offer T42 (1.3207) - a proprietary tungsten high speed steel containing 10 percent cobalt. T42 is harder than most high-speed steels and has in addition a reasonably good toughness. T42 is used mainly for tools requiring maximum abrasion resistance and medium toughness.
Applications
- End Mills
- Fine Blanking, Stamping, Blanking
- Gear Cutting, Shaving and Shaping Tools
- Special Cutting Tools
- Blades for Sawing Machines
- Broaches and Reamers
- All kinds of profile blades for wood machining are manufactured from sheets.
- For severely stressed tools for fine and roughing work
- Wood working tools and tools for cold work.

| Process | Temperature (°C) | Details |
|---|---|---|
| Soft Annealing | 800–860°C | Heat to 800–860°C, cool slowly in furnace. Maximum Brinell hardness of 300. |
| Stress Relieving | 600–650°C | Heat to 600–650°C, hold for 1 hour, air cool. Reduces machining stresses to prevent distortion. |
| Hardening | 1200–1230°C | Harden from 1200–1230°C followed by quenching in oil, air, or a warm bath at 540°C. Hardness after quenching: 64–66 HRC. |
| Tempering | 540–570°C | Temper at 540–570°C at least twice for 65–67 HRC. Hardness after tempering: 64–67 HRC. |
