What's The Wear Resistant Steel Plate Used For?

Wear Resistant Steel Plate refers to the special plate products used for working conditions where large-area wear required, generally including ordinary wear-resistant steel plate and composite wear-resistant steel plate. Ordinary wear-resistant steel plate is the steel plate through heat treatment, quenching, tempering and other processes to change the internal atomic structure of the steel, or adding some alloy elements such as chromium to change the original characteristics of the steel. The composite wear-resisting steel plate is composed of low carbon steel plate and an alloy wear-resisting layer. The surface of the low alloy steel is made by surfacing a certain thickness of the plate with high hardness and good wear resistance of the alloy wear-resisting layer.


What are the advantages of wear-resistant steel plate?

  • Excellent wear resistance.

As the name suggests, wear-resistant steel has excellent wear resistance. The composite wear resistant alloy layer is generally 1/3~1/2 of the total thickness, with carbon content up to 4 ~ 5% and chromium content up to 25 ~ 30%. The metallographic volume of Cr7C3 carbide reaches more than 50%, it’s the macroscopic hardness is HRC56-62 and the hardness of chromium carbide is HV1400 ~ 1800. Because carbides are vertically distributed in the wear direction, their wear resistance is more than doubled even when compared with casting alloys of the same composition and hardness.

  •   Good impact resistance

The base layer of composite wear resistant steel plate is made of low carbon steel or low alloy steel plate, which can withstand the high load from medium and wear in the material conveying system.


  • Good heat resistance

The carbon steel base layer is recommended to be used at no more than 380℃, and the wear-resistant layer is no more than 600℃. Vanadium, molybdenum and other alloys added to the wear resistant layer can withstand≤800℃, for example, 15CrMo, 12Cr1MOV and other low-alloy steel plates are recommended not higher than 540℃ and heat resistant stainless steel substrate not higher than 800℃.


  • Good corrosion resistance

The alloy layer of wear-resisting composite steel plate contains highly chromium, which makes the plate more anti-rust and anti-corrosion, can be used in coal cylinder and funnel to prevent coal sticking.

What’s the wear resistant steel plate used for?

Medium speed coal grinder barrel liner, fan impeller shell, dust catcher inlet flue, ash tube, bucket turbine liner, separator connection tube, coal crusher liner, coal hopper and crusher liner, burner, coal hopper and funnel liner, air preloader bracket shingle, separator guide blade.

Mining machinery

Lining of feeding trough and funnel, hopper bushing, fan blade, bottom plate of pusher, coke guide liner, ball mill lining, bit stabilizer, screw feeder bell and its base, lining of kneading machine bucket, ring feeder and bottom plate of a dump truck.

Cement plant: chute liner, end bushing, cyclone dust collector, powder separator blade and guide blade, fan blade and liner, recovery bucket liner, screw conveyor bottom plate, pipe assembly, frit cooling tray liner, conveyor chute liner, where require wear-resistant steel plates with 8-30mm thickness.

Loaders, bulldozers, excavators, rotary drilling RIGS and drill pipes need to be made of extremely hard and wear-resistant steel plates. The available materials are hardox 500/550/600 high-strength wear-resistant steel plates of 20-60mm thickness.

Loading machinery such as unloading mill chain plate, hopper lining board, grab blade board, automatic tipping truck tipping board, dump truck. It is recommended wear-resistant steel plate with a thickness of 25-45mm.

Mining machinery such as ore, stone crusher lining board, blade, conveyor lining board. The available material is HARDOX 500/600 wear-resistant steel plate with a thickness of 10-30mm.

Construction machinery such as cement pusher tooth plate, concrete mixing building, mixer lining board, dust remover lining board, brick machine die board. It is recommended wear resistant steel plates with a thickness of 10-30mm.

In addition, wear-resistant steel can also be used in sanding machine barrel, blades, as well as a variety of bearing structures, railway wheel structures and rollers.
