Flame hardening molds
For mold work where local surface hardening is required.
HMD5 is supplied as a flame-hardening cold work die steel for mold, die and tooling applications where buyers need practical toughness, local surface hardening and cut-to-size supply from China. It is commonly referenced with GB 7CrSiMnMoV / CH-1 under GB/T 1299.
Use these names for inquiry preparation when comparing Chinese cold work die steel references.
| Common Name | Chinese Grade | Alternative Name | Standard / Reference | Product Family |
|---|---|---|---|---|
| HMD5 | 7CrSiMnMoV | CH-1 | GB/T 1299 | Cold Work Tool Steel |
Equivalent names are for purchasing reference. Final supply should be confirmed by chemical composition, delivery condition, MTC and order requirements.
Typical HMD5 reference composition and Chinese 7CrSiMnMoV standard range are listed below for purchasing reference. Final chemical composition should be confirmed by the agreed supply standard, delivery condition and material test certificate.
| Element | HMD5 Typical % | 7CrSiMnMoV GB/T 1299 Range % |
|---|---|---|
| C | 0.70 | 0.65–0.75 |
| Si | 1.00 | 0.85–1.15 |
| Mn | 1.00 | 0.65–1.05 |
| P | — | ≤0.030 |
| S | — | ≤0.015 |
| Cr | 1.20 | 0.90–1.20 |
| Mo | 0.20 | 0.20–0.50 |
| V | — | 0.15–0.30 |
| Cu | — | ≤0.25 |
| Cu + Ni | — | ≤0.55 |
HMD5 is commonly referenced in China together with 7CrSiMnMoV / CH-1. Equivalent names are for purchasing reference only. Final supply should be confirmed according to chemical composition, delivery condition, order standard and MTC.
HMD5 is selected where practical toughness, local surface hardening and tooling repairability are important.
For mold work where local surface hardening is required.
For forming, stamping or tooling applications by drawing.
For components that need toughness plus surface wear resistance.
For blocks requiring localized surface hardening after machining.
For applications where practical toughness and repairability matter.
