Wear Resistant Chromium Carbide Plate

Wearalloy Super-Clad Steel Plate

Super-Clad is a super-tough material that lasts up to 30 times longer than mild steel and up to 20 times longer than manganese steel in applications that demand unusually high abrasion resistance. It is manufactured by metallurgically bonding a composite of chromium-iron-carbides to mild steel substrate, in a process that yields a highly abrasion-resistant "overlay" material. It also has good impact capabilities.  


600 BHN

Wearalloy Super-Clad Plate is manufactured by metallurgically bonding a composite of chromium-iron-carbon alloy and chromium carbides to a mild steel substrate in a process that yields a highly abrasion-resistant “overlay” material that will also sustain moderate impact.

Available Services:

Use plasma or air arc. Plasma arc is preferred for a factory environment. Air arc is satisfactory at on-site locations for trimming and fitting precut plates or cutting strips to length. 

Can be cold rolled or pressed to 10" radius-hot pressed to a tighter radius. Consult our Engineering Department for further information. 

Plasma cut holes oversize, then weld in pre-machined mild steel plug. When accuracy is required, mild steel plug should be drilled after installation. Countersink holes can be dug using Buggo machine with a compatible plasma torch.

Strips and plates can be welded into position using mild steel electrodes to weld the base plate to a mild steel component. When welding to a dissimilar metal, use AWS E309-16 hydrogen electrode. When plates larger than 4 sq. ft. will be exposed to high impact, plug weld the central area of plates to prevent fatigue caused by micro environments. For hardfacing over low hydrogen welds, we recommend two passes with 26% to 30% chromium content welding electrode.
