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.
