AKD-397 HRC:44-48 Hardfacing Wire for Forging Die Repair.
A hardfacing welding wire designed for surfacing repair of hot forging dies made from 5CrMnMo, 5CrNiMo, and 5CrNiSiW steels, delivering a hardness range of HRC 44-48 after welding.
Product Overview
AKD-397 is a hardfacing welding wire used for surfacing repair of hot forging dies, particularly those made from 5CrMnMo, 5CrNiMo, and 5CrNiSiW steels. It is formulated to restore wear resistance and structural integrity in dies subjected to high thermal and mechanical stress during forging operations.
The wire has a typical chemical composition of C: 0.2–0.5%, Si: 1.0%, Mn: 1.0%, S: 0.01%, P: 0.02%, Cr: 5.0%, and other elements totaling ≥1.5%. These elements contribute to the final hardness and wear resistance of the deposited metal, which achieves a hardness range of HRC 44–48 after welding.
Application: It is used for repairing surfacing welding of hot forging dies, and can also be used for repairing old forging dies made of 5CrMnMo, 5CrNiMo, and 5CrN iSiW steels. Typical Chemical Compostion(%): C:0.2-0.5 Si:1.0 Mn:1.0 S:0.01 P:0.02 Cr:5.0 Other：≥1.5.
Key Benefits
Hardness Range HRC 44–48.
The deposited metal achieves a hardness of HRC 44–48, which is suitable for maintaining wear resistance in hot forging die applications under high-temperature and high-stress conditions.
Compatibility with 5CrMnMo, 5CrNiMo, and 5CrNiSiW Steels.
AKD-397 is specifically formulated for use on dies made from 5CrMnMo, 5CrNiMo, and 5CrNiSiW steels, ensuring good metallurgical compatibility and reduced risk of cracking during repair.
Controlled Sulfur and Phosphorus Levels.
With sulfur at 0.01% and phosphorus at 0.02%, the wire helps minimize the risk of hot cracking and improves the ductility of the weld deposit.
Balanced Carbon and Alloy Content.
The carbon content of 0.2–0.5% and chromium content of 5.0% provide a balance between hardness and toughness, supporting durability in repeated thermal cycles.
Where It Is Used
- Repair of hot forging dies made from 5CrMnMo steel.
- Rebuilding worn surfaces on dies made from 5CrNiMo steel.
- Surface restoration of dies made from 5CrNiSiW steel.
- Hardfacing applications requiring HRC 44–48 hardness.
Who It Is For
- Forging die repair shops specializing in maintenance of hot forging tools.
- Steel and die manufacturing facilities with in-house repair capabilities.
- Maintenance teams responsible for extending the service life of high-wear forging dies.
Problems It Solves
- Wear and surface degradation in hot forging dies made from 5CrMnMo, 5CrNiMo, and 5CrNiSiW steels.
- Lack of a consistent, compatible hardfacing wire for repairing dies with complex alloy compositions.
- Cracking or poor adhesion during repair due to mismatched chemical composition or hardness.

Technical Features
- Hardfacing wire with deposited metal hardness of HRC 44–48.
- Chemical composition: C: 0.2–0.5%, Si: 1.0%, Mn: 1.0%, S: 0.01%, P: 0.02%, Cr: 5.0%, other elements ≥1.5%
- Designed for use on 5CrMnMo, 5CrNiMo, and 5CrNiSiW steels.
- Suitable for surfacing repair of hot forging dies under high thermal and mechanical load.
Use Guide
- Clean the surface of the die thoroughly before welding to remove oil, scale, and contaminants.
- Use a controlled welding current and travel speed to avoid overheating and distortion.
- Allow the weld deposit to cool slowly after welding to maintain hardness and reduce residual stress.
How It Compares
AKD-397 is intended for hardfacing repair of hot forging dies and is not a substitute for general-purpose welding wires. It differs from standard low-alloy or carbon steel wires in its higher chromium and carbon content, which enables higher hardness and wear resistance. It is not suitable for structural welding where toughness and ductility are prioritized over hardness.
