Description
NM450 Wear Plate for Chute Liners and Processed Wear Parts
NM450 Wear Plate is a medium-to-high hardness abrasion-resistant steel plate for buyers who need longer service life than NM400 while keeping practical cutting, drilling, countersinking and welding review for custom liner fabrication.
EB Chute Liner supplies NM450 plates as standard plate, cut-to-size wear plate, drilled plate, countersunk bolt wear plate and drawing-based replacement liner parts for chutes, hoppers, conveyor transfer points, crushers, screens and truck-body wear zones.
Where NM450 fits
Between NM400 and NM500
Use NM450 when NM400 wears too fast but NM500 may be unnecessarily hard, costly or difficult for the intended processing.

Sliding abrasion with moderate impact
Suitable for chute liners, hopper liners, transfer points and other liner plates exposed to abrasive material flow.

Drawing-based processing
Can be supplied as cut, drilled, countersunk, slotted or plug-weld-hole wear plates after drawings are confirmed.

Standard RFQ Specification for NM450 Wear Plate
Use this specification module when requesting NM450 wear plates for chute liners, wear liner plates and processed replacement parts. Ranges below are quotation references; final supply should follow drawings, mill certificate, processing review and application condition.
NM450 specification reference
| Parameter | Quotation reference | RFQ confirmation required |
|---|---|---|
| Material grade | NM450 / AR450 class abrasion-resistant steel plate, or equivalent grade agreed before production. | Required standard, equivalent grade acceptance and mill certificate requirement. |
| Hardness range | Typical AR450-class reference: about 425-475 HBW for common plate thickness ranges. | Required hardness band, test location and certificate format. |
| Thickness range | Common RFQ range: 6-80 mm for chute liner plates; thinner or thicker options depend on stock and processing feasibility. | Nominal thickness, tolerance, flatness requirement and allowed substitution. |
| Plate size | Cut-to-size plates, nested liner sets, small replacement plates or full-size plates according to drawing. | Length, width, corner radius, bevel, bend direction and drawing revision. |
| Processing | Cutting, drilling, countersinking, slotting, plug weld holes, edge preparation and marking. | Hole diameter, pitch, countersink angle, edge distance and tolerance. |
| Fixing method | Bolt-on, countersunk bolt, weld-on, plug weld, stud-backed or modular liner layout. | Site access, replacement method, flush-surface requirement and backing structure. |
| Applications | Mining chutes, cement transfer chutes, aggregate hoppers, conveyor transfer points, crusher feed zones and truck-body liners. | Material handled, impact height, particle size, moisture, temperature and expected service life. |
Price and quotation factors
| Cost factor | What changes the quotation | Buyer input needed |
|---|---|---|
| Material grade | NM450 vs NM400/NM500, equivalent grade acceptance and certificate requirement. | Target grade and whether equivalent AR450-class material is acceptable. |
| Thickness and dimensions | Plate thickness, yield, nesting efficiency, cut length and scrap rate. | Drawings or dimension list for each liner plate. |
| Hole processing | Drilled holes, countersunk holes, plug weld holes, slots and tolerance. | Hole pattern, bolt size, countersink detail and edge distance. |
| Quantity | Batch size affects material procurement, cutting setup and unit processing cost. | Pieces per drawing, total weight or annual replacement demand. |
| Inspection and documents | Hardness test, dimensional inspection, material certificate and packing photos. | Required inspection standard and documents before shipment. |
| Packing and delivery | Export pallet, steel frame, crate, moisture protection, marking and destination. | Destination country, port, delivery terms and packing requirement. |
MOQ, lead time and document checklist
| Item | Typical RFQ reference | Notes |
|---|---|---|
| MOQ | Flexible for drawing-based replacement parts; better pricing normally starts from batch orders or full liner sets. | Send total quantity and drawing list for review. |
| Lead time | Usually depends on stock plate, thickness, drilling/countersinking load and inspection requirements. | Confirm urgent shutdown dates before quotation. |
| Drawings | PDF, DWG, DXF, STEP, sketch or measured photo package. | Show material flow direction and installation side where possible. |
| Inspection | Dimension check, visual inspection, hardness check and material certificate when required. | State certificate language and project document format. |
| Packing | Export pallet, crate or steel-frame packing with plate marking. | Heavy plates need forklift access and safe unloading plan. |
NM400 vs NM450 vs NM500 selection
| Grade | Typical buyer reason | Use with caution when |
|---|---|---|
| NM400 Wear Plate | General abrasion protection, easier processing and balanced cost. | Service life is too short in heavier abrasion. |
| NM450 Wear Plate | Improved abrasion resistance while retaining practical drawing-based processing. | Impact is severe or bending/welding requirements are strict. |
| NM500 Wear Plate | Higher hardness for severe sliding abrasion and high-wear transfer points. | Processing complexity, cracking risk and impact toughness must be reviewed. |
Fixing method guide
| Fixing method | Where it fits | Design notes |
|---|---|---|
| Bolted liner plate | Transfer chutes, hoppers and areas needing planned replacement. | Provide hole diameter, bolt size, pitch, access direction and washer/countersink detail. |
| Countersunk bolt plate | Material flow side needs a flush or low-profile surface. | Confirm countersink angle, bolt head height and allowable wear allowance. |
| Plug weld hole plate | Backing plate or module designs where rear access is limited. | Confirm plug weld hole diameter, pitch, welding side and grinding requirement. |
| Weld-on plate | Fixed areas with lower replacement frequency. | Review preheat, welding procedure and crack risk for hard wear plate. |
| Modular liner layout | Large chute surfaces with uneven wear patterns. | Use smaller replaceable sections to reduce spare cost and shutdown time. |
