High Quality 4kh5mfs Hot Work Die Steel Properties - China

4KH5MFS Hot-Work Die Steel is a high-performance hot-work die steel** renowned for its excellent high-temperature strength, resistance to thermal fatigue, and good toughness; it performs exceptionally well under demanding operating conditions such as aluminum alloy die casting and hot forging.

Its core performance characteristics are primarily reflected in the following aspects:

* **Chemical Composition and Basic Properties**: As a chromium-molybdenum-vanad ium alloy steel, the chemical composition of 4Kh5MFS (approximately 0.4% C, 1% Si, 5% Cr, 1.3% Mo, 0.4% V) establishes the foundation for its superior hot-work performance.

In the annealed state, its hardness typically does not exceed **HB 235–241**.

* **Resistance to Tempering Softening**: The material maintains high hardness and resists softening at elevated temperatures.

Studies indicate that 4Kh5MFS surpasses certain similar steel grades (such as 4Kh5V2FS) in terms of thermal stability.

* **High-Temperature Strength**: Its tensile strength decreases as the temperature rises.

Summary

Overall, 4KH5MFS Hot-Work Die Steel is a time-tested, versatile material.

Its design philosophy strikes an excellent balance between **hardness, strength, and thermal fatigue resistance at high temperatures**, making it a classic choice for applications such as aluminum alloy die casting and hot forging.
