Manufacturer:
Rajlaxmi Industries
Origin:
Ahmedabad, Gujarat, India
Delivery:
Pan India & Global Export
Product Overview
High-Velocity Oxygen Fuel (HVOF) thermal spray tungsten carbide coated screws delivering extreme surface hardness (>1200 HV).
Rajlaxmi Industries offers advanced HVOF (High-Velocity Oxygen Fuel) thermal spray coating on screws. A dense, micro-fine layer of Tungsten Carbide / Cobalt Chrome is sprayed at supersonic velocity, forming a pore-free barrier against abrasive recycling materials.
Material Grades
Substrate EN41B / 42CrMo with Tungsten Carbide (WC-Co-Cr) HVOF layer
Hardness Rating
Surface Hardness: 1100 - 1300 HV (70 - 74 HRC equivalent)
Key Technical Advantages
- Ultra-dense coating with porosity less than 0.5%
- Supreme wear resistance for reprocessing post-consumer plastic scrap
- Extended life up to 400% compared to conventional gas nitriding
