M35 High Speed Steel Heat Treatment Process

The heat treatment of M35 high speed steel plays an important role in enhancing hardness, red hardness, wear resistance and toughness. Heat treatment process generally consists of three stages: Annealing, Quenching and Tempering. Each step is explained in more detail below:

• Annealing: The primary goal of heat treatment to anneal M35 is to soften the steel that eliminates internal stress and can enhance the machinability.
• Quenching：In M35 heat treatment, Quenching is made by rapid cooling,Its purpose is to increase the hardness, red hardness and wear resistance of the steel.
• Tempering：In M35 heat treatment, tempering removes quenching stress and adjusts the hardness and toughness of steel at the same time, while ensuring red hardness and wear resistance.

Performance After Heat Treatment

Following correct hardening and tempering, M35 high-speed steel can reach the following characteristics：

• High Hardness：

  The hardness can be up to HRC 63~65 after heat treatment of M35, it can keep high hardness under high temperature, and it has very high wear resistance, it can be used under high temperature condition for a long time.

• High wear resistance：

  M35 is able to exhibit very high wear resistance after heat treatment. It can show good cutting performance when cutting hard materials at high speed. Use to manufacture all kinds of high and ultra-hard saw blade, drill bit, tap, broach, hob and other high load tools.

• Very good toughness characteristics：

  M35 high hardness can maintain good toughness and anti-cracking ability, can withstand greater impact force, can reduce the collapse and cracking damage of die cutting edge. It has good bending strength under high hardness and high impact load.

How to keep it after heat treatment

• Prevent surface oxidation and corrosion:

  You can regularly apply with anti-rust oil or anti-rust layer on top of the steel surface so as to form a protective film to prevent rust. In coastal area, coating can be used for steel to increase its corrosion resistance.

• Prevent high temperature damage:

  It should try to prevent M35 steel or cutting tools work for a long time in the red-hot temperature than the design Because long-term use will lead to low hardness and wear resistance. During the processing, a suitable coolant can be used to lower the processing temperature.

• Regular maintenance of heat treatment performance:

  Long-term use of M35 tools, wear resistance of hardness may drop, need to re-heat treatment. The standard process of M35 steel should be strictly followed when re-heat treatment, in order to restore the original performance of M35.
