High-temperature strength · Thermal fatigue resistance · Specifically for die casting and hot forging 15–53 μm / 53–150 μm / -300 mesh ~ -500 mesh

H13 hot-work tool steel powder (corresponding to ASTM H13, GB 4Cr5MoSiV1, JIS SKD61, and DIN 1.2344) is a pre-alloyed powder that exhibits excellent high‑temperature strength—maintaining high hardness at 500–600°C—along with superior thermal fatigue resistance and wear resistance. This non‑vacuum atomized powder features excellent sphericity, outstanding flowability, and an oxygen content of ≤500 ppm, making it well suited for processes such as laser powder bed fusion, laser cladding, hot isostatic pressing, MIM, and powder metallurgy compaction and sintering.
