Wear-Resistant Steel Plates for Heavy Wear Conditions
Wear-Resistant Steel Plates
Overview
Wear-resistant steel plates are used where heavy wear and damage often occur. These plates are made with a strong base and a durable surface layer.
Composition and Structure
Wear-resistant plates are made from two layers:
-
Base Layer (Cold-Rolled Steel Plate):
Used for strength and bending resistance. -
Surface Layer (Aluminum Alloy):
Provides high wear resistance.
🔹 Usually, the alloy layer is 1/3 to 1/2 of the total thickness.
🔹 The layers are joined by special welding machines.
🔹 One to three alloy layers may be stacked.
🔹 Small horizontal cracks often form due to shrinking. These are normal and expected.
Alloy Components
The alloy layer contains:
-
Cobalt (main element)
-
Manganese
-
Molybdenum
-
Niobium
-
Nickel
These elements form cementite fibers that run straight from the surface down.
Even at 500℃, the layer stays strong and resists rust.
Types of Plates
Wear-resistant plates are divided into three main types:
-
General-Purpose:
Used in many industries. -
Impact-Resistant:
Made for high-impact situations. -
Heat-Resistant:
Handles high temperatures well.
Common Applications
These plates are widely used in:
-
Steel and metal factories
-
Coal processing
-
Power plants
-
Concrete mixing
-
Mining and construction
-
Glass and brick kilns
They are often chosen because they cost less over time than many other materials.
