HB OM200
Weld Overlay Wear Plates
Overview:
HB SM200 utilizes submerged arc welding technology to fuse chromium carbide composite cladding onto a mild steel base. The cladding features a high density of chromium carbides uniformly distributed across its thickness, forming a bimetallic structure that delivers exceptional abrasion resistance while retaining ductility for forming and welding applications.
HB SM200 performs very well under severe abrasion and low to moderate impact environments.
