AKD-60-O Hardfacing Wire for Wear-Resistant Applications.
A high-chromium, high-carbon hardfacing wire designed for severe wear environments, delivering a hardness of 58-64 HRC in the as-deposited condition.
Product Overview
AKD-60-O is a hardfacing wire used in industries requiring resistance to abrasion, impact, and erosion, including cement, steel, electric power, mining, and coal processing. It is suitable for rebuilding or protecting components such as wear plates, conveying channels, buckets, fans, and fan blades.
The wire has a chemical composition rich in chromium and carbon, with chromium content between 25.0% and 28.0% and carbon between 3.5% and 5.5%. This composition supports the formation of hard carbides that resist wear under heavy service conditions.
AKD-60-O is supplied with a hardness range of 58-64 HRC in the as-deposited state, providing a durable surface layer that maintains integrity in high-wear applications.
Application: Used in cement industry, steel, electric power, mining, coal processing, and other wear-resistant industries. Suitable for wear plates, conveying channels, buckets, fans, fan blades, etc.
Key Benefits
High Hardness in As-Deposited Condition.
The deposited metal achieves a hardness of 58-64 HRC directly after welding, offering immediate resistance to abrasive wear without requiring post-weld heat treatment.
High Chromium Content for Wear Resistance.
With chromium content between 25.0% and 28.0%, the wire forms a microstructure with hard chromium carbides that resist abrasion and impact in harsh industrial environments.
Suitable for Critical Wear Components.
Designed for use on parts exposed to continuous wear, such as conveying channels, buckets, fan blades, and wear plates, where extended service life is essential.
Controlled Carbon and Alloy Content.
Carbon content between 3.5% and 5.5%, along with silicon (0.50-2.50%) and manganese (0.50-2.50%), balances hardness, toughness, and weldability.
Where It Is Used
- Wear plates in cement and mining equipment.
- Conveying channels and chutes in coal processing.
- Bucket and blade surfaces on excavators and fans.
- Rebuilding worn components in electric power and steel industries.
Who It Is For
- Welding contractors servicing industrial wear parts.
- Maintenance teams in cement and mining operations.
- Fabricators repairing or building wear-resistant components.
- Engineers specifying hardfacing materials for high-abrasion environments.
Problems It Solves
- Wear failure in components like buckets and fan blades due to insufficient hardness or poor carbide formation.
- Short service life of parts in abrasive environments caused by inadequate alloy content in the deposited metal.
- Need for multiple welding passes or post-weld treatments to achieve required hardness.

Use Guide
- Prepare the base material by removing rust, oil, and scale before welding.
- Use recommended welding parameters to maintain the desired hardness and avoid excessive dilution.
- Control interpass temperature to prevent cracking and maintain the integrity of the hardfacing layer.
- Clean the deposited layer between passes to remove slag and ensure good adhesion of subsequent layers.
How It Compares
AKD-60-O is a high-carbon, high-chromium hardfacing wire with a hardness of 58-64 HRC. It is not intended for structural welding. Compared to lower-chromium wires, it offers superior abrasion resistance but may be more brittle. It is not suitable for applications requiring ductility or low-temperature toughness. For less severe wear, lower-carbon alternatives may be considered.
