Main Uses of Wear-Resistant Steel Plates
Wear-resistant steel plates are used in industries that involve heavy impact, abrasion, and harsh environments. These industries include mining, construction, metallurgy, and power generation.
1. Mining Dump Trucks
The truck frame is made using low-alloy, high-strength steel.
-
A closed box structure is used for the main beam to improve strength.
-
The carriage floor is tilted (usually 12°) and made from high-hardness steel to resist impact and wear.
-
No rear baffle is included to ease unloading.
-
A service life of over 10 years is typically ensured.
2. Loaders and Bulldozers
The buckets of loaders and bulldozers are welded from wear-resistant steel.
-
Cutting edges use medium manganese alloy steel.
-
Side blades and angle reinforcements are made from high-strength steel.
-
Designed for earthmoving and heavy digging tasks.
3. Crusher Components
Many crusher parts require wear-resistant materials:
| Crusher Type | Key Parts Using Wear-Resistant Steel |
|---|---|
| Jaw Crusher | Jaw plate, side guard plate, elbow plate |
| Impact Crusher | Plate hammer, impact block |
| Hammer Crusher | Hammer head, liner, screen plate |
| Cone Crusher | Crushing wall, mortar wall |
4. Construction and Industrial Equipment
Various equipment in engineering, mining, and metallurgy use wear-resistant parts:
Engineering Machinery
-
Bucket blades, drill rods, cutting blades
-
Used in loaders, bulldozers, pavers, and excavators
Loading and Unloading Machinery
-
Chain plates, hopper liners, grab blades
-
Used in automatic dump trucks and conveyors
Construction Machinery
-
Mixer liners, cement pushers, dust collectors
Metallurgical Machinery
-
Liners for sintering machines, scrapers, and conveyors
Mining Equipment
-

Other Uses
-
Sand mill barrels, rollers, railway and port machinery parts
5. Power Generation Equipment
Used in thermal power plants for:
-
Coal mills, coal hoppers, distributors, and feeders
-
Lining plates are added to reduce wear and extend life
Performance of NM Series Steel Plates
The NM Series wear-resistant steel by Lian Steel is known for:
-
Thin size range: 3–25mm
-
Good plate shape and cutting ability
-
Stable quality and high strength
