H11

The H11 alloy offered by Huizhou Chengxing Mould Steel Co. Ltd. is a high‑performance steel used for moulds and dies. The supplier lists the chemical composition identifier as approximately 1.2343, and specifies a heat‑treatment window of 800 °C to 860 °C held for 2 to 5 hours. After treatment the material is furnace‑cooled, a process that enhances dimensional stability. These parameters are intended to achieve a hardened condition suitable for high‑temperature tooling.

In the steel industry, H11 typically contains 0.38‑0.44 % carbon, 4.75‑5.5 % chromium and 1.0‑1.5 % molybdenum, giving it a standard hardness of 48‑53 HRC after quenching and tempering. Its density is about 7.85 g cm‑3, a value common to alloy tool steels. The alloy is recognised for good machinability, allowing precision machining of complex mould geometries. Standard tolerances for H11 forged bars are ±0.2 mm for critical dimensions.

Automotive, aerospace and general manufacturing firms source H11 for injection‑mould and die applications where thermal fatigue resistance is critical. The supplier notes flexible minimum order quantities and offers shipping under FOB or CIF terms, with payment by L/C or T/T. Buyers should request the ISO and SGS certificates mentioned in the listing and obtain a material test report confirming chemical composition and hardness before finalising the purchase.

Huizhou Chengxing Mould Steel Co. Ltd. is based at 1006, B Block, Yunshan Road, Huizhou, Guangdong 516000, China. The company holds a harbour‑level verification tier, indicating that its registration details have been validated by the sourcing platform. The public profile does not provide a response rate or average reply time, so initial communication speed should be assessed directly. Chengxing specialises in producing alloy steel products, with the H11 alloy listed among its offerings.

The supplier states that it can meet international standards and references ISO and SGS certifications for its steel grades. No explicit production capacity or annual turnover is disclosed, therefore purchasers should request detailed capability statements. Shipping can be organised under FOB or CIF incoterms, and payment terms include letters of credit or telegraphic transfer. Prospective buyers are encouraged to verify the supplied material test reports against the required specifications.
