Chromium Carbide Liners
The carbide hardness is approximately 1750 Brinell. The matrix is approximately 450 Brinell, giving a macro-hardness of approximately 52 Rc. The relief checks that form in this material are desirable, and indicate there is no simultaneous cracking away of the hard layer from the mild steel base.
The mild steel backing material allows Chromium Carbide plates to be rolled into sections for pipes and cyclones. Fixing can easily be arranged by welding studs on to the mild steel backing. The material can also have plasma-cut holes or inserts for bolts fitted.
The high Chromium alloy has good corrosion resistance, and retains its hard properties up to approximately 600 °C. The superior wear properties of Chromium Carbide plates dramatically reduces plant downtime & maintenance costs.
The extreme hardness of the carbide particles make Chromium Carbide plates ideally suitable for applications involving sand, medium sized ore bodies, coal properties of large-scale hardfaced welding at a fraction of the cost of this means of protection. The high chromium content gives Chromium Carbide plates approximately the same corrosive properties as high chromium (14%) steels.
