DWX40 high-speed steel is a tool steel with extremely high hardness and wear resistance, which is widely used in mold making, cutting tools, stamping tools and other fields. This paper will conduct an in-depth analysis of DWX40 high speed steel from the aspects of chemical composition, heat treatment process, mechanical properties, physical properties, material advantages and application fields.
1. Chemical composition analysis.
The chemical composition of DWX40 high speed steel mainly includes elements such as carbon, chromium, tungsten, cobalt, manganese, silicon and molybdenum. Among them, carbon is the main element to improve the hardness and strength of steel; Chromium can improve the wear resistance and corrosion of steel; Tungsten can improve the hardness and wear resistance of steel; Cobalt can improve the toughness and wear resistance of steel; Manganese can improve the strength and hardness of steel; Silicon can improve the oxidation resistance and wear resistance of steel; Molybdenum can improve the hardness and wear resistance of steel.
2. Heat treatment process.
The heat treatment process of DWX40 high speed steel mainly includes quenching, tempering and hardening. Quenching is the heating of steel to a high temperature and then rapid cooling to improve the hard strength of the steel. Tempering is the process of heating the steel to a lower temperature after quenching, and then cooling it slowly to reduce the hardness of the steel and improve the toughness and wear resistance of the steel. Hardening is the process of heating the steel again to high temperatures after tempering, and then cooling it rapidly to further improve the hardness and strength of the steel.
3. Mechanical properties.
DWX40 high speed steel has high hardness, strength, and toughness. Its hardness can reach more than 60HRC, the flexural strength can reach more than 2000MPa, and the toughness can reach more than 10Jcm. These excellent mechanical properties enable DWX40 high speed steel to maintain good working performance under high temperature, high pressure and high wear conditions.
4. Physical properties The physical properties of x40 high-speed steel mainly include density, thermal conductivity, specific heat capacity and magnetic permeability. Its density is about 85g cm, the thermal conductivity is about 20w (m·k), and the specific heat capacity is about 05j (g·k) with a permeability of about 10μm/m。These physical properties make DWX40 high speed steel have good thermal stability and thermal conductivity in practical applications.
