Material of the Wear-Resistant Layer in Chromium Carbide Cladding Plate 5+5

Alloy Composition

The wear-resistant layer is made from a high-chromium alloy.
Its composition includes:

• Carbon (C): About 5.0%

• Chromium (Cr): 27–30%

• A martensitic base with a high volume of Cr₇C₃ carbides, making up over 60% of the structure.

Hardness

• Alloy layer hardness: HRC 57–65

• Carbide hardness: HV 1400–1800

These values ensure high resistance to wear and surface damage.

Wear Resistance

The plate offers excellent durability:

• 20–25 times more wear-resistant than low carbon steel

• 8–12 times more than stainless and high manganese steel

• Over 15 times more than standard high carbon high chromium plates

High Temperature Resistance

• Standard type: Withstands up to 600°C

• High-temperature type: Withstands up to 1000°C

Impact Resistance

• The wear-resistant alloy layer is metallurgically bonded to the base plate.

• It is strong against impact and does not peel off during use.

Applications of Composite Wear-Resistant Plates

These plates are widely used to strengthen surfaces exposed to frequent wear. They are used in steel plants, cement factories, power stations, mines, fans, and more.
