Wodon are specialized in produce Chromium carbide overlay wear plate, we adopt submerged arc welding technoloy which contains more Cr content ranging from 25% to 45%. the carbide volume fraction on the microstructure is above 50% and maximum hardness of hard particle is HV1800. the ASTM-G65 methode A is under 0.16g.

Chromium Carbide bimetallic plate:

Medium/Low carbon steel + Abrasion resistant layers → Chromium carbide bimetallic plate with metallurgical bonding

(Q235/Q345B + Chromium Carbide overlay → Chromium carbide bimetallic plate by Submerged arc or Open arc welding technology)

Detail:

The wear resistant layer has a high amount of chromium carbide hard particles. These particles are distributed evenly throughout the layer, creating a strong microstructure. The hardness is HRC 58~65 and depends on the overlay's thickness.

The main ingredients of Wodon plate are C(%): 3.0~6.0 and Cr(%): 25~45. This chemical proportion results in a large amount of Cr7C3 chrome carbide hard particles. The micro-hardness (up to HV1800) of these particles throughout the layer will guarantee a super wear resistant surface.

The overlay and base plate are metallurgical bonding. The overlay will penetrate into base plate about 0.8~1.8 mm, reaching up to 350 Mpa in our tests.

WD1200 wear plate can be used for severe abrasion applications.
