Available surface conditions: drawn, ground, hot rolled, cold rolled.
Heat Treatment for T-1 High-Speed Steel
- Soft annealing requires a protective atmosphere of around 3 hours with an 850-900°C. Then comes slow cooling to air cooling to 10°C per hour down to 700°C.
- Stress management for around 2 hours from 600°C to 700°C. Afterward, slow cooling to 500°C for desired results. For the steps mentioned above, preheating the atmosphere for hardening gives better results.
- Preheating results in 450-500°C and 850-900°C with the right temperature. Maintaining the right temperature is essential to get the right types of hardness.
- Another imperative way is to handle everything for 1 hour at 560°C every time with two tempers.
Usage of T1 High Speed Steel
The T1 High speed steel is used for several options like:
- Gear tools
- Trailers
- Cranes
- Milling tools
- Complex blades
- Cold extrusion dies
- Bridge frames
- Earthmoving equipment
- Mining equipment
- High-temperature bearings
- Structural components
- Truck frames and bodies
- Impact-resistant metal cutting tools
- Other tools like cutters and punches
- Booms (lattice-type and telescopic)
- Transport vehicle frames and bodies
- Storage container support frames
- High-speed cutting tools (such as electric saws)

Surface Treatment
Surface treatment for steel grade makes an appropriate choice for PVD coating. In case there’s a small diffusion zone then better manage oxidized layers and compounds.
