10 · Wear Plate
From heavy impact to extreme abrasion: AR400, AR450 and AR500 plates plus chromium-carbide bimetallic plate — the right grade for every wear zone, supplied cut-to-size, rolled or drilled per drawing.
The plate grades
370–430 HBW
AR 400 Plate
High toughness, excellent weldability and formability — moderate impact: buckets, hoppers, chutes, feeders.
420–475 HBW
AR 450 Plate
The hardness-toughness balance — crushing, heavy mining and excavation.
470–530 HBW
AR 500 Plate
Maximum abrasion resistance — impact-mill liners, severe abrasion zones, transfer points.
58–65 HRC · Premium
Bimetallic Plate (CCO)
Chromium carbide (Cr7C3) overlay for extreme sliding abrasion — fines chutes, cyclones, ducts.
| Material | Hardness | Impact | Abrasion | Dominant mechanism | Recommended application |
|---|---|---|---|---|---|
| AR 400 | 370 – 430 HBW | Impact + abrasion | General equipment with moderate impact | ||
| AR 450 | 420 – 475 HBW | Impact + abrasion (balanced) | Crushing, heavy mining, excavation | ||
| AR 500 | 470 – 530 HBW | Severe abrasion | Mining, transport, transfer zones | ||
| Bimetallic (CCO) | 58 – 65 HRC | Sliding abrasion | Abrasive fines, chutes, ducts, cyclones |
Overlay technology
A chromium carbide layer fusion-bonded to a mild-steel backing by submerged- or open-arc welding. The microstructure is primary Cr7C3 carbides in a eutectic austenite matrix: the hard carbides take the abrasion while the ductile plate absorbs impact and keeps the product weldable, formable and easy to install.
58–63 HRC · Cr7C3 > 35%
60–64 HRC · Crack- and bead-free surface
M30 — regular wear duty, 59–64 HRC: excellent abrasion resistance with moderate impact tolerance.
M70 — W, Nb, Ti, V and Mo added to the overlay for compound carbides: the strongest abrasion and impact resistance of the range.
M10 — non-magnetic wear plate for strong magnetic environments: 5× the life of 304 stainless in magnetic separators and iron removers.
Standard CCO
The as-welded overlay keeps its characteristic ribbed bead pattern — full abrasion resistance, at the lowest cost per square metre.
Smooth CCO
A flat, practically crack- and bead-free face: lower friction, less material build-up and 1.5–4× the service life.
700 HB / 63 HRC
High-chrome white iron metallurgically bonded to a mild-steel backing by a vacuum-welding process: extreme hardness on the working face, weldable and impact-tolerant behind it. Chocky bars, wear buttons, strips, wear plates and crusher hammer tips — standard shapes or custom sizes.
