  • Discover Spot Supply M2 Steel Bars Unique Chemical Composition - China

    price: 1001.00 Dollar US$

    **Carbon (C) element**

    - The carbon content in M2 steel bars is generally between 0.80% and 0.90%.

    Carbon is one of the most critical strengthening elements in high-speed steel.

    Its main function is to form various carbides with alloying elements, such as tungsten carbide (WC), molybdenum carbide (MoC), vanadium carbide (VC), etc.

    These carbides play a role of dispersion strengthening in the structure of high-speed steel, just like embedding many tiny "hard spots" in the steel matrix, greatly improving the hardness and wear resistance of the steel.

    For example, when the carbon content is in the right range, the hardness of M2 high-speed steel can reach 63-66HRC after quenching and tempering.

    **Tungsten (W) element**

    - The tungsten content in M2 steel bars is generally between 5.50% and 6.75%.

    Tungsten is an important alloying element, which mainly forms carbides such as WC.

    These carbides have extremely high stability at high temperatures and can effectively prevent the grain growth of high-speed steel during high-temperature operations such as cutting.

    This allows M2 high-speed steel to maintain high hardness and strength in high temperature environments, which is the so-called red hardness.

    For example, at a high temperature of 600℃, the hardness of M2 high-speed steel can still be maintained at around 55HRC, which is mainly due to the stable carbides formed by tungsten.

    **Molybdenum (Mo) element**

    - The molybdenum content in M2 steel bars is about 4.50% - 5.50%.

    Molybdenum and tungsten have similar effects in high-speed steel.

    It can also form carbides, such as MoC, and participate in dispersion strengthening.

    The presence of molybdenum can partially replace the role of tungsten and can refine the grains to a certain extent.

    Compared with high-speed steel containing only tungsten, M2 high-speed steel containing molybdenum performs better in toughness.
