Yongxiang H21/SKD5: Precision Steel
In the high-stakes world of industrial tooling, the choice of material can make or break operational efficiency. H21 tool steel and its Japanese equivalent SKD5 (3Cr2W8V) have emerged as critical alloys for applications demanding extreme heat resistance, toughness, and dimensional stability. Yongxiang, a premier H21 tool steel manufacturer and custom SKD5 steel supplier based in China, is redefining industry standards by delivering tailored solutions that meet global demands for precision and durability.
H21 & SKD5: The Alloys for Extreme Environments
H21 tool steel, classified as a hot-work steel, is engineered to withstand prolonged exposure to high temperatures without losing hardness or cracking. Its composition—typically 0.35% carbon, 2.2–2.7% chromium, and 0.5–1.2% vanadium—ensures a balance of wear resistance and thermal fatigue strength. This makes it ideal for manufacturing dies, extrusion tools, and forging components in industries like automotive and aerospace.
SKD5 (3Cr2W8V), the Japanese counterpart to H21, shares similar properties but is optimized for specific applications requiring enhanced toughness under cyclic thermal loads. Both alloys excel in scenarios where conventional steels would deform or fail, such as die-casting aluminum or processing abrasive materials.
