Wearalloy Super-Hard Chrome Plate
70-72 Rockwell C
Wearalloy Super Chrome Plate is a unique material with a base plate of Wearalloy 400 (also available with mild steel) and plated with a surface coating of .020” electro plated chrome. Super Chrome’s chemistry produces a surface designed especially for areas with severe problems of sliding wear, erosion and sticking. Wear rates of Super Chrome have shown to be comparable to that of ceramics under specific wear conditions depending on particle size. Power plants, coal prep plants and cement plants provide ideal conditions for this .020 electro-plated chrome plate to be cost effective – especially when down time matters.

Electro-plated chromium has the lowest coefficient of friction of all metals. Wearalloy Super Hard Chrome plate combines this characteristic with an extremely dense grain structure that keeps materials, wet or dry form sticking to its surface. It solves material sticking and "hang-up" problems common in bulk material handling.
Wearalloy Super Hard Chrome plate is one of the hardest materials suitable for bulk material transfer surfaces. It achieves a hardness of 70-72 Rockwell C for chrome plating. The plate's increased hardness gives it superior resistance to sliding wear, abrasion, impact, and erosion.
Wearalloy Super Hard Chrome's surface finish is not affected by most corrosive elements. It resists corrosion due to water, sulfuric acid, hydrogen sulfide, and nearly all organic acids.
Reminder: all non-stock sizes must first be cut with CNC plasma, then follow the procedures listed below for method that best fits your application.
- This is the best method for environments with significant impact and vibration.
- Studs should always be installed to the non-chrome side.
- Stud and base material should be made from compatible materials.
- Stud diameter must not exceed the thickness of the base plate material.
- Weld only to the non-plated side.
- Keep the base material under 250 degrees C. A wet rag can be placed on the plate surface to draw heat from the plate, keeping the plate at a cooler temperature.
- Tack welding is recommended for attaching to a base surface of the structural steel surface. Remember to keep the tack spaced out in even intervals, below the chrome surface.
- MIG welding is the latest disruptive method for tack welding. If stick welds are used, we recommend a 7018, low hydrogen rod.
- Hard chrome surface can be drilled and if necessary, countersunk. We recommend That Ford Steel prepare the base material with countersunk holes prior to hard plating. This ensures the chrome surface will remain continuous, avoiding the possibility that a premature wear spot develops around the hole.
- Bolt heads can be hard-plated as well. This is highly recommended for continuously flowing surfaces such as feeder liners and chutes.
