The Iron-Based Alloy Powder for Laser Cladding range is developed for laser cladding, laser metal deposition (LMD), and powder-fed directed energy deposition (DED). These iron-based laser cladding powders provide a cost-effective material solution for wear-resistant surface enhancement, dimensional restoration, industrial component repair, and remanufacturing.
Available grades can deliver hardness values of up to 70 HRC, depending on alloy composition and processing conditions. High-chromium iron-based formulations are available for applications requiring a combination of wear and corrosion resistance, while other grades can be selected for hydraulic equipment, engineering machinery, wear components, and hot-work die repair.
Manufactured using gas atomization, the powders feature spherical particle morphology, controlled particle-size distribution, and good flowability. These characteristics support stable powder feeding and consistent delivery to the melt pool during laser cladding and DED processing.
Under suitable process conditions, the powders can produce dense coatings with metallurgical bonding, stable multi-layer buildup, and a reduced cracking tendency. For customers seeking a gas-atomized iron-based alloy powder for wear-resistant laser cladding and die repair, multiple alloy grades and customized particle-size ranges are available according to the substrate, target hardness, coating thickness, and service environment.
