Chromium Carbide Wear Plate



Product Introduction

    Chromium carbide wear plate are manufactured by welding one or multiple abrasion resistant layers on a medium or low carbon steel  (Q235, Q345) or stainless steel (SS 304, SS 309, SS 310) base plate. The overlay alloy has a high amount of chromium carbide hard particles.

Microstructure: The carbide (Cr7C3) volume fraction on the microstructure is above 50%.

Hardness: Chromium carbide hard particles are distributed evenly throughout the layer, creating a strong microstructure,The hardness is between HRC 57-62 and depend on the overlay's thickness: Overlay thickness over 10 mm. Hardness over 62 HRC.

Wear resistance: Our test shows that the Abrasion resistant performance of hardfacing overlay steel plate is 20 times higher than Mild steel and 8 times than heat treated steel.

Key Advantages

High wear performance: the property of wear resistance is much higher than the heat resistant steel and casting wear-resistant cast iron.

Easy Processing: made in standard sizes, which had light weight, convenient and flexible processing.

Flat surface and nice outlooking , Outstanding welding strength.

Better Cost Performance: a better cost performance 2-3 times than ordinary materials, the per unit area cost only the a half of using the same kind of ingredients by hand electrode surfacing.

Strong Shock Resistance: strong shock resistance and crack resistance, that suitable for vibration, hard shock working conditions.
