M42 Super High Speed Steel Supplier

M42 Super High-Speed Steel is a premium alloy known for its exceptional hardness and hot hardness, making it ideal for tough cutting applications. It contains around 8% cobalt, which enhances its wear resistance and maintains sharpness at high temperatures. With a heat-treated hardness of 68 to 70 HRC, M42 is perfect for machining high-strength steels, tough alloys, and nonferrous materials in industries like

aerospace, oil, and power generation. It offers superior performance compared to standard high-speed steels and provides a cost-effective alternative to carbide tools.

M42 Super High Speed Steel Supplier

Amardeep Steel supplies M42 Super High-Speed Steel, a premium cobalt high-speed steel known for its exceptional hardness and hot hardness. With around 8% cobalt, M42 offers superior wear resistance and maintains its sharpness and hardness even under heavy-duty and high-production cutting conditions. It achieves a high heat-treated hardness of 68 to 70 HRC, making it ideal for machining high-strength and pre-hardened steels, tough alloys, and nonferrous super alloys used in aerospace, oil, and power generation industries.

M42 Super High Speed Steel Heat Treatment

Annealing:

Annealing is recommended after hot working and before re-hardening.
Heat the temperature to 850°C at a rate not exceeding 220°C per hour.
Hold at this temperature for at least one hour per inch of thickness (minimum two hours).
Cool slowly in the furnace or air to ambient temperature.
Achieve a maximum hardness of 269HB or lower.

Hardening:

Use a vacuum, atmosphere furnace, or properly rectified salt bath for hardening.
Pre-heat thoroughly to 820-870°C, then transfer to the high-temperature salt bath or furnace.
Heat to the final hardening temperature:
- 1160-1180°C in salt bath, or
- 1180-1190°C in atmosphere or vacuum furnaces.
Quench without further soaking into salt at 540-595°C or warm oil.
Complete the quenching process in air.

Tempering:

Perform tempering immediately after quenching.
Heat uniformly to the tempering temperature range of 510-620°C.
Hold at this temperature for at least two hours (one hour per inch of total thickness).
For M42 high-speed steel, triple tempering is strongly recommended.
