AKD-507 HRC:40-45 for 1Cr13 Surfacings on Shafts and Valves.
A surfacing welding wire for 1Cr13 applications on carbon or alloy steel components operating below 410°C, delivering hardness in the range of 40-45 HRC.
Product Overview
AKD-507 is a surfacing welding wire designed for depositing 1Cr13-type alloy on carbon steel or alloy steel shafts and valves. It is intended for service temperatures below 410°C and delivers a hardness of 40-45 HRC in the as-welded condition.
The wire is formulated with a chemical composition that includes 13.0-15.0% Cr, 0.10-0.20% C, 1.0% Si, 2.0% Mn, and trace elements totaling at least 2.0%. Sulfur is limited to 0.015% and phosphorus to 0.019% to maintain weld metal integrity and resistance to cracking.
AKD-507 is supplied as a solid wire for use in gas metal arc welding (GMAW) or flux-cored arc welding (FCAW), depending on the application and equipment available.
Application: 1Cr13 surfacing welding wire, carbon steel or alloy steel shafts and valves with working temperature below 410°C.
Key Benefits
Hardness Range 40-45 HRC.
The deposited metal achieves a hardness of 40-45 HRC, suitable for wear-resistant surfacing on components exposed to moderate mechanical stress and thermal cycling.
Controlled Chromium Content
With 13.0-15.0% Cr, the weld metal provides a balance of corrosion resistance and mechanical strength appropriate for 1Cr13 service conditions.
Low Sulfur and Phosphorus.
Sulfur at 0.015% and phosphorus at 0.019% reduce the risk of hot cracking and improve weld metal ductility.
Suitable for Shafts and Valves.
The wire is specifically recommended for surfacing applications on shafts and valves where dimensional stability and surface hardness are critical.
Where It Is Used
- Surfacing of 1Cr13 on carbon steel or alloy steel shafts.
- Wear-resistant overlays on valves operating below 410°C.
- Repair and reinforcement of components subject to abrasion and moderate thermal load.
Who It Is For
- Welding consumable distributors supplying surfacing wires for industrial maintenance.
- Valve and pump manufacturers requiring consistent surfacing performance.
- Maintenance teams performing repair welding on rotating or high-pressure components.
Problems It Solves
- Achieving consistent hardness in the 40-45 HRC range on 1Cr13 surfacing deposits without over- or under-alloying.
- Reducing the risk of cracking in surfacing welds due to high sulfur or phosphorus content.
- Matching the correct surfacing wire to 1Cr13 service requirements in shafts and valves below 410°C.
