HSP-41 Tool Steel Physical Properties

1. Density: approximately 7.0-7.5 kg/dm³
2. Tensile strength (Rm) : ≥ 592 MPa; Yield strength (Rp₀.₂) : ≥ 191 MPa
3. Impact toughness (Charpy KV) : approximately 32 J; Elongation and reduction of area are both lower than 50 %
4. Factory hardness: approximately HB 310-320 (approximately HRC 30)
5. Thermal performance: The thermal diffusivity, thermal conductivity and thermal expansion rate are all suitable for long-term application under thermal load conditions

HSP-41 Tool Steel Mechanical & Performance Properties

1. Extremely high wear resistance: Due to the uniform network structure formed by tungsten, molybdenum and vanadium carbides, it is very suitable for long-term continuous cutting use.
2. Good impact toughness: Unlike many hard steels, it still retains a certain degree of plasticity in a high-hardness state.
3. Strong thermal stability: It is not prone to deformation at high temperatures and its hardness remains stable.
4. Solderability and repairability: Official data also indicates that it can be repaired by welding or partially reconstructed.

HSP-41 Tool Steel Product Applications

Suitable for making tools that require extreme wear resistance and high-temperature stability, such as:

1. Single-edge drill bits, hobs, small punching and shearing tools.
2. High-temperature cutting components of special materials.
3. High-speed metal cutting and graphite/composite material processing tools, etc.

For industrial use: In environments with high requirements for tool life and large heat loads.
