Stainless Steel 316L Powder (for Laser Cladding)

Laser cladding uses high-energy lasers to metallurgically bond 316L powder to substrates, forming dense, corrosion-resistant coatings or repair layers. Key applications include:  

Marine Engineering & Shipbuilding 
Components: Ship valves, propeller shafts, seawater pump parts.  
Advantages: Resists seawater corrosion and biofouling, extending equipment lifespan.  

Petrochemical Industry  
Components: Pipeline interiors, reactor vessels, valve sealing surfaces.  
Advantages: Withstands corrosive media (e.g., H₂S, CO₂), preventing leaks.  

Medical Devices  
Components: Surgical tools, implant surface coatings.  
Advantages: Biocompatible, corrosion-resistant to bodily fluids, and easy to sterilize.  

Aerospace  
Components: Engine parts, landing gear repairs.  
Advantages: Resists oxidation and fatigue under alternating high/low temperatures.  

Mold & Machinery Remanufacturing  
Components: Injection molds, roller surface repairs.  
Advantages: Restores dimensions while improving surface hardness (e.g., combined with tungsten carbide reinforcement).  

Nuclear Energy  
Components: Cooling system parts in nuclear reactors.  
Advantages: Resists stress corrosion cracking in radioactive environments. 

Physical Properties:  
Particle size: 15–53 μm (powder-fed laser cladding) or 53–150 μm (coaxial powder feeding).  
High sphericity: Ensures uniform flow and dense, pore-free cladding layers.  

Process Advantages:  
  - Low heat input minimizes substrate distortion, suitable for thin-walled repairs.  
  - Clad layer hardness: ~200–250 HV, adjustable via post-heat treatment.
