AKD-212 Hardfacing Wire for Wear-Resistant Surface Repair.
A hardfacing wire with a hardness range of HRC 54-57, designed for rebuilding worn surfaces on heavy-duty components exposed to abrasion and impact.
Product Overview
AKD-212 is a hardfacing wire used for surface repair and wear protection on components such as gears, buckets, and mining machinery. It delivers a wear-resistant deposit with a hardness of HRC 54-57, suitable for applications where surface integrity and durability are critical.
The wire has a typical chemical composition of C: 0.3-0.5%, Si: 1.5%, Mn: 2.0%, S: 0.06%, P: 0.02%, Cr: 5.0-8.0%, and other elements totaling at least 1.0%. This composition supports high hardness and resistance to abrasive wear in demanding service environments.
Application: Applicable to the surface of various worn parts, such as gears,bucke ts, mining machinery, etc.Applicable to the surface of various worn parts, such as gears, buckets, mining machinery, etc. Typical Chemical Compostion(%): C:0.3-0.5 Si:1.5 Mn:2.0 S:0.06 P:0.02 Cr:5.0-8.0 Other：≥1.0.
Key Benefits
High Hardness for Abrasion Resistance.
The deposited metal achieves a hardness range of HRC 54-57, which provides strong resistance to abrasive wear on surfaces subjected to continuous friction and impact.
Stable Wear Performance in Heavy-Duty Applications.
The chemical composition, including chromium and carbon content, supports consistent hardness and wear resistance in components like mining buckets and gear teeth.
Suitable for Surface Rebuilding.
AKD-212 is designed for overlay welding to restore dimensions and improve surface durability on worn parts without requiring full replacement.
Controlled Alloying Elements
The presence of at least 1.0% of other elements, along with balanced carbon, silicon, and manganese, contributes to a stable microstructure and consistent performance.

Use Guide
- Select welding parameters based on the base material thickness, joint configuration, and desired deposition rate.
- Clean the surface thoroughly before welding to remove oil, rust, scale, and contaminants.
- Use proper shielding gas or flux as required for the selected welding process to ensure a sound, clean deposit.
- Control heat input to avoid excessive dilution and maintain the desired hardness in the final deposit.
How It Compares
AKD-212 is a hardfacing wire with a hardness of HRC 54-57, suitable for wear protection in high-abrasion environments. It differs from softer hardfacing wires with lower hardness values, which may wear faster under severe conditions. Compared to wires with lower chromium content, AKD-212 offers enhanced wear resistance due to its Cr: 5.0-8.0% range. It is not intended for structural welding or general-purpose joining.
