Wholesale Wear Plate Manufacturers & Supplier

The choice depends on particle velocity, impingement angle, and mechanical impact. Choose Solid Sintered Tungsten Carbide Plates for low-angle fine-particle slurry erosion, high-speed pulverizing, or when thickness is constrained (e.g., centrifuges, wire guides). Tungsten carbide offers up to 93 HRA hardness and can withstand temperatures up to 650°C with near-zero mass loss. Choose Chromium Carbide Overlay (CCO) Bimetallics when your application involves structural framing, heavy rock gouging (lump sizes > 50 mm), or requires rolling/forming into curved chutes. The ductile mild steel base plate absorbs mechanical deflections, while the hardface layer resists abrasion.

CCO plates can be cut on-site using high-definition CNC plasma, laser, or abrasive waterjet cutting. Oxy-acetylene flame cutting is only effective from the mild steel backing toward the hardface. CCO plates can also be rolled into internal or external cylinders using standard three-roll pyramid plate bending machines, provided the hardfacing side faces inward (or outward with adjusted radius allowances). In contrast, Solid Tungsten Carbide plates cannot be flame or plasma cut; they must be wire-EDMed, sliced with high-grit diamond saws, or custom sintered to net-shape drawings directly at our foundry.

Visible fine transverse cracks (known as "check cracking") on the surface of CCO plates are an intentional metallurgical requirement, not a defect. During weld solidification, the high-chromium carbide hardfacing contracts at a different rate than the carbon steel backing. The formation of evenly spaced micro-cracks relieves residual cooling stresses. These cracks stop cleanly at the fusion boundary and do not propagate into the ductile base plate, preventing structural failure while preserving impact absorption.

For high-vibration environments like vibrating screens and rock transfer drop boxes, avoid rigid front welding. Instead, we recommend: 1) Stud Welding: Threaded studs drawn-arc welded directly to the base plate's rear face, allowing blind-mounting with vibration-dampening Belleville spring washers. 2) Countersunk Inserts: Plasma-cut countersunk holes fitted with matching hardened conical bolts and sealed with plug-weld caps. 3) Interlocking Keyways: Slide-in channel rail configurations that eliminate exposed bolt heads in the primary abrasive stream.

To support prototype qualification, our MOQ for standard stock dimensions or custom sample preforms is 1 piece. For custom sintered tungsten carbide shapes or drawing-based wear liners, engineering sample lead time is 7 to 10 days. Full 20-foot or 40-foot containerized production runs are manufactured and dispatched from our Jiangxi facility within 20 to 25 calendar days, backed by comprehensive pre-shipment dimensional and metallurgical inspection dossiers.
