NM450 wear resistant steel plate is a quenched and tempered high-strength abrasion resistant steel with a nominal hardness of approximately 450 HBW. It is widely used in mining equipment, dump truck bodies, crushers, excavators, cement plants and bulk material handling systems.
NM450 wear resistant steel plate export prices remained relatively stable during the first half of 2026, supported by steady overseas demand from the mining, quarrying, cement and construction equipment industries, while fluctuations in iron ore and ferroalloy prices caused moderate market volatility. Standard GB/T 24186 quenched and tempered (Q&T) NM450 steel plates were typically quoted at USD 630–740 per metric ton (FOB China) for mainstream stock specifications.
Thin-gauge plates, heavy-gauge plates, premium steel mill brands and value-added processing services such as CNC cutting, drilling, bending or painting generally increased export prices by USD 30–100 per ton.
Looking ahead to the third quarter of 2026, the market is expected to experience moderate upward pricing pressure as alloy surcharges and raw material costs continue to fluctuate, although actual quotations will vary depending on steel mill production schedules and international market demand.
What Is the Price of NM450 Wear Resistant Steel Plate in 2026?
The 2026 FOB China export price of standard GB/T 24186 NM450 quenched and tempered wear resistant steel plate generally ranges from USD 630 to 740 per metric ton for standard stock sizes.
Final prices vary according to plate thickness, steel mill brand, heat treatment quality, order quantity, inspection requirements, machining services, export destination and real-time alloy raw material costs.Prices may also vary depending on the selected steel mill, delivery schedule and destination market.
The above price range applies to standard NM450 plates supplied in the fully quenched and tempered (Q&T) condition with Mill Test Certificates issued in EN 10204 Type 3.1 format. For premium brands, non-standard dimensions, extra-thick plates, third-party inspections (SGS, BV or TÜV), ultrasonic testing (UT), or customized machining services, export prices may increase to USD 750–850 per metric ton.

Price Disclaimer：
The prices shown above are indicative FOB China export reference prices for standard NM450 wear resistant steel plates supplied in the quenched and tempered condition. Actual quotations may change daily depending on steel mill availability, alloy surcharges, exchange rates, order quantity, inspection requirements, machining services, export packaging and destination ports.
All standard export orders are supplied with Mill Test Certificates (MTC) in EN 10204 Type 3.1 format. Optional ultrasonic testing (UT), third-party inspections, impact testing, shot blasting, primer painting and precision machining are available upon request and may affect the final quotation.
For the most accurate project pricing, buyers are encouraged to provide the required dimensions, quantity, technical specifications, processing requirements and delivery terms (FOB, CFR or CIF) when requesting a quotation.
All Key Factors That Determine the Final NM450 Steel Plate Price
The final price of NM450 wear resistant steel plate depends on several factors beyond the base steel cost, including plate thickness, steel mill brand, heat treatment, processing requirements, inspection standards and delivery terms. Understanding these factors helps buyers compare quotations more accurately.
Thickness & Plate Dimensions
Plate thickness has a significant impact on pricing. 8–30 mm is the most common stock range and usually offers the most competitive prices. Thin plates (4–6 mm) require tighter rolling tolerances, while heavy plates (70 mm and above) involve longer rolling and heat treatment cycles, resulting in higher production costs. Non-standard dimensions may also increase material utilization losses and processing charges.
Processing & Inspection Requirements
Value-added services such as flame or laser cutting, drilling, bending, shot blasting and primer painting will increase the final quotation. Standard export orders are supplied with a Mill Test Certificate (MTC) in EN 10204 Type 3.1 format, while optional services such as ultrasonic testing (UT), SGS/BV inspection or impact testing may incur additional costs.
Order Quantity & Delivery Terms
Larger orders generally benefit from more competitive factory pricing, while small trial orders may have slightly higher unit costs due to fixed production and logistics expenses. Final quotations also vary depending on the selected trade terms (FOB, CFR or CIF), export packaging requirements and destination port.
Steel Mill Brand
NM450 plates from different steel mills may vary in price due to differences in production equipment, thickness tolerance, hardness consistency and quality control. Premium mills generally provide more consistent mechanical properties, while standard mills may offer more competitive pricing for general wear applications.
Performance & Cost Comparison: NM450 vs Hardox450, XAR450 and AR450
Many buyers focus only on the initial purchase price when comparing wear-resistant steel plates. However, the total cost of ownership also depends on delivery time, processing capability, material availability and maintenance costs.
Compared with imported 450 HB wear plate grades, NM450 offers several advantages for standard mining, quarrying and bulk material handling applications:
- Comparable hardness (approximately 420–480 HBW) for conventional abrasive wear conditions.
- Typically 15%–30% lower procurement cost than imported 450-grade wear plates, depending on supplier, market conditions and order volume.(Actual price differences vary depending on supplier, destination market, exchange rates and order quantity.)
- Shorter lead times with readily available stock from Chinese steel mills.
- Flexible processing services, including cutting, drilling, bending and welding preparation, helping reduce downstream fabrication costs.
For applications requiring exceptional low-temperature toughness or extremely demanding operating conditions, buyers should compare detailed mechanical properties in addition to price.
