Product details
P20 High Hard Steel is a popular grade of tool steel that is commonly used in the manufacturing of molds, dies, and other high-performance components that require excellent wear resistance and high hardness. It is often used in industries such as plastic molding and die casting. Key Features of P20 High Hard Steel:- 1. Hardness:- o P20 High Hard Steel can be heat-treated to achieve high hardness, typically around 28-32 HRC. This makes it well-suited for applications requiring durability and resistance to wear. 2. Composition:- o It contains a mix of carbon, chromium, manganese, silicon, and nickel, which contribute to its hardness, toughness, and ability to resist deformation under high stress. 3. Applications: o Molds and Dies: P20 High Hard Steel is widely used for manufacturing injection molds, die-casting molds, and other molding tools. o Plastic Molding: It's ideal for injection molds, offering the right balance between wear resistance and machinability. o Other Tooling: It is also used for tooling applications that require good polishability and surface finish. 4. Machinability: o P20 High Hard Steel offers excellent machinability in its annealed state, making it relatively easy to machine before it undergoes heat treatment. o Once heat-treated, its hardness increases, which can make it more difficult to machine, so proper tooling and methods are needed. 5. Heat Treatment: o Typically, the steel can be pre-hardened before use, and it can also be further heat-treated to achieve even higher hardness if necessary. 6. Weldability: o It has moderate weldability, though pre-heating and post-weld heat treatment may be required to prevent cracking during welding. Summary: P20 High Hard Steel is a versatile tool steel that balances toughness, hardness, and machinability, making it a popular choice for manufacturing molds, dies, and other tooling components. Its ability to resist wear, deformity, and provide an excellent finish makes it ideal for high-demand applications.
