HFW's Steel Industry Manufacturing and Overhaul Work

For the steel industry, HFW is primarily engaged in manufacturing and rebuilding mill rolls and various related components. We have extensive experience reducing wear caused by heat, galling, corrosion, and related steel mill operating conditions.

HFW is known for being a one-source solution for manufacturing and overhaul work. Our thermal spray coatings and hardfaced overlays are supported by in-house machining, precision grinding, and inspection capabilities. This work is typically helpful in reducing wear seen in galvanizing, pickling, rolling mill, and chemical processing operations within a steel mill. HFW has also worked with many industries to offer hard chrome plating alternatives.

Thermal Spray Coatings for Steel and Heavy Industry

Thermal spray technology is one of HFW's specialties, particularly HVOF (High Velocity Oxy-Fuel) and tungsten carbide coatings for high-wear and corrosive environments.

Why Choose HFW for Thermal Spraying?

• Over 70 years of experience applying high-performance coatings
• Ability to rebuild and restore worn components to OEM specs
• Reduce downtime and extend equipment life
• Replace hard chrome where the application supports an HVOF coating alternative

Coating Types We Offer:

• Tungsten carbide/cobalt for abrasion resistance
• Stellite® alloys for wear and corrosion
• Chrome and nickel-based alloys
• Ceramic coatings for insulation and heat resistance
• HFW 512 proprietary alloy: a nickel-based HVOF coating developed by HFW with over 40 years of documented performance data. In one documented chemical processing application, standard thermal spray and HFW 512 helped produce a 30× service life improvement. See our article on HFW 512 for details.
