AKD-61-O Hardfacing Wire for Wear-Resistant Applications.
A high-chromium, high-carbon hardfacing wire designed for severe abrasion and impact resistance in industrial wear components.
Product Overview
AKD-61-O is a hardfacing wire with a hardness range of HRC 60-65, formulated for use in high-wear environments. It contains 27.0-32.0% chromium and 4.0-6.0% carbon, which provides a hard, wear-resistant microstructure in the deposited metal.
The wire is used in the cement, steel, electric power, mining, and coal processing industries for rebuilding or protecting components subject to abrasive and erosive wear. Applications include wear plates, conveying channels, buckets, fans, and fan blades.
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 for Abrasion Resistance.
With a hardness range of HRC 60-65, AKD-61-O delivers excellent resistance to abrasive wear in high-stress environments.
High Chromium Content for Wear and Corrosion Resistance.
The 27.0-32.0% chromium content forms a stable carbide structure that enhances wear resistance and provides moderate corrosion resistance.
Suitable for High-Wear Industrial Components.
Designed for use on wear plates, conveying channels, buckets, fans, and fan blades where material loss from impact and abrasion is a concern.
Controlled Carbon and Silicon Levels.
Carbon content of 4.0-6.0% and silicon of 0.50-1.50% help maintain hardness and weldability while supporting the formation of hard carbides.
Where It Is Used
- Wear plates in cement and mining equipment.
- Conveying channels and chutes in bulk material handling.
- Bucket teeth and wear liners in excavators and loaders.
- Fan blades and housing components in power and industrial fans.
- Rebuilding worn surfaces in coal processing machinery.
Who It Is For
- Welding contractors servicing industrial wear parts in mining and cement plants.
- Maintenance teams in power generation and steel production facilities.
- Fabricators rebuilding or hardfacing components for harsh service environments.
Problems It Solves
- Wear-related failure of components such as buckets, fan blades, and conveying channels due to abrasion and impact.
- Inconsistent hardness or poor wear resistance from low-chromium or low-carbon hardfacing materials.
- Lack of a dedicated hardfacing wire with high chromium and controlled carbon for severe wear applications.

Use Guide
- Select welding parameters based on the base material thickness, joint configuration, and required deposition rate.
- Clean the base metal surface thoroughly before welding to remove oil, rust, and scale.
- Use shielding gas as specified for the welding process to ensure proper arc stability and weld metal quality.
- Control interpass temperature to avoid excessive grain growth and maintain hardness in the deposited metal.
How It Compares
AKD-61-O is a high-carbon, high-chromium hardfacing wire with HRC 60-65 hardness. It is not suitable for applications requiring ductility or toughness. For lower hardness and better toughness, consider lower-chromium or lower-carbon alternatives. For applications requiring higher impact resistance, a material with lower carbon and higher manganese may be preferred.
