Overview of Wear Resistant Steel Plate

Our NM series wear-resistant steel plates (400HWB, 450HBW, 500HBW) are high-strength, abrasion-resistant steels specifically designed for demanding applications where severe wear and impact are major challenges. Manufactured through advanced hot rolling and Quenched & Tempered (Q+T) processes, these plates offer exceptional hardness, extending the lifespan of your equipment significantly and reducing costly downtime. They are the ideal choice for heavy-duty industries seeking superior durability and performance.

Key Features
Superior Hardness: Nominal hardness ranging from 400 HBW to 500 HBW ensures outstanding resistance to sliding and impact wear.
Extended Service Life: Outperforms conventional mild steel by 3-5 times, leading to significant cost savings on maintenance and replacement.
Excellent Impact Toughness: Maintains good mechanical properties even in cold environments, crucial for mining and quarry applications.
Reliable Performance: Consistent quality from reputable Chinese mills (with original mill marking for traceability).
Good Weldability & Formability: Despite high hardness, our plates can be welded and processed with appropriate techniques.

Application

Construction Machinery

Mining & Quarrying Equipment

Heavy Duty Transport

400HBW and 500HBW plates are widely used to manufacture excavator buckets, cutting edges, and bulldozer blades. Their high hardness protects the equipment from severe abrasion during earthmoving and digging operations, extending the bucket's service life by 3-5 times.

In the mining industry, 500HBW is the ideal material for crusher liners, vibrating screens, feeders, and transfer chutes. It provides exceptional resistance to sliding wear and impact from ores and rocks, minimizing downtime for maintenance.

Used as lining plates for dump truck bodies and concrete mixer drums. Using high-strength wear-resistant steel allows for thinner plates (lightweight design) while ensuring the vehicle body can withstand the constant friction of loading and unloading heavy materials like gravel and coal.

FAQ

Q: How do you ensure the quality of your NM wear-resistant steel plates?
A: We only supply steel plates from top-tier Chinese mills (like Wugang, Xingcheng, Baosteel). Every plate comes with the Original Mill Test Certificate (MTC) that tracks the heat number, chemical composition, and mechanical properties. We also support Third-Party Inspection (like SGS, BV) before shipment to verify hardness and thickness.

Q: What is the difference between 400HBW and 500HBW? Which one should I choose?
A:400 HBW: Has good toughness and is easier to cut, bend, and weld. Ideal for structural parts that need moderate wear resistance, like truck bodies.
500 HBW: Much harder and more wear-resistant but harder to process. Best for parts facing severe abrasion, like crusher liners and cutting edges.
If you are not sure, tell us your application, and our engineers will recommend the best grade.

Q: Can you provide cutting and processing services?
A: Yes! Besides standard raw plates (2m x 6m or 2m x 12m), we have advanced CNC Laser and Plasma cutting machines. We can cut the plates into specific sizes, drill holes, or bend them according to your drawings.

Q: Your photos show 12-meter long plates. How do you ship them?
A: For standard 6-meter plates, we load them into 20ft containers.
For 12-meter long plates, we usually load them into 40ft Open Top containers or ship via Bulk Vessel to ensure safe unloading at your destination. We use strong steel strips for bundling to prevent damage.

Q: Can I order a small quantity for trial?
A: Yes, our MOQ is 3 Tons (approx. 1 piece of thick plate). We understand the need to test quality before bulk purchasing. However, for LCL (Less than Container Load) shipments, the unit shipping cost might be slightly higher than Full Container orders.
