AKD-172 Hardfacing Wire for Wear-Resistant Surface Repair.
A hardfacing wire with a hardness range of HRC 44-48, suitable for rebuilding worn surfaces on components exposed to abrasive and impact loads.
Product Overview
AKD-172 is a hardfacing wire designed for surface repair and buildup on components subjected to wear, such as gears, buckets, and mining machinery. It delivers a hardness of HRC 44-48 in the as-deposited condition, providing resistance to abrasion and impact in demanding service environments.
The wire's typical chemical composition includes carbon (C: 0.2-0.4%), silicon (Si: 1.0%), manganese (Mn: 1.5%), sulfur (S: 0.007%), phosphorus (P: 0.02%), chromium (Cr: 3.0%), and other elements totaling at least 1.0%.
It is supplied as a solid wire for use in gas metal arc welding (GMAW) or flux-cored arc welding (FCAW) processes, with the composition tailored to achieve a wear-resistant deposit.
Application: Applicable to the surface of various worn parts, such as gears, buckets, mining machinery, etc.Applicable to the surface of various worn parts, such as gears, buckets, mining machinery, etc. Typical Chemical Compostion(%): C:0.2-0.4 SI:1.0 Mn:1.5 S:0.007 P:0.02 Cr:3.0 Other：≥1.0.
Key Benefits
High Hardness for Abrasion Resistance.
The deposited metal achieves a hardness of HRC 44-48, which helps resist wear from abrasive materials and repeated impact in applications like mining and earthmoving equipment.
Controlled Chemical Composition
The wire contains 0.2-0.4% carbon, 1.0% silicon, 1.5% manganese, 3.0% chromium, and other elements totaling at least 1.0%, supporting a balanced wear-resistant microstructure.
Low Sulfur and Phosphorus Content.
With sulfur at 0.007% and phosphorus at 0.02%, the wire minimizes the risk of hot cracking and improves weld metal toughness.
Suitable for Surface Rebuilding.
Designed for restoring worn surfaces on gears, buckets, and mining machinery, extending component life and reducing replacement costs.
Where It Is Used
- Rebuilding worn gear teeth.
- Repairing bucket teeth and cutting edges on excavators.
- Surface hardening of mining machinery components.
- Restoring surfaces on parts exposed to abrasive wear.
Who It Is For
- Welding shops specializing in hardfacing and surface repair.
- Maintenance teams in mining and heavy equipment operations.
- Fabricators rebuilding worn industrial components.
Problems It Solves
- Wear-related failure of gears and buckets due to lack of surface hardness.
- Inconsistent repair quality from wires with uncontrolled chemistry.
- Cracking in weld deposits caused by high sulfur and phosphorus levels.

How It Compares
AKD-172 is a hardfacing wire with HRC 44-48 hardness, suitable for wear resistance in components like gears and buckets. It differs from lower-hardness wires by offering higher abrasion resistance. Compared to wires with higher carbon content, AKD-172 balances hardness with lower risk of cracking due to its controlled sulfur and phosphorus levels.
