LINKUP 100 & 200 Series CCO wear plate is a bi-metallic plate, consisting of a mild steel base ASTM A36 ( EN10025-2 S235JR or JIS G3101 SS400), with a high alloyed wear- resistant cladding: Chromium carbide(Cr7C3), primary carbide volume ﹥50%, the micro-hardness up to HV1800. The mild steel base plate allows the product to be cut, bent, welded, bolted, or studded to existing structures. Physical Properties: Excellent abrasion resistance of the hardface layer, according to ASTM G65 the hardface outlasts mild steel by 20 times and 8 times than heat-treated steel. Bonding layer: the cladding layer penetrates the base plate about 0.8-1.8mm(350Mpa).
