Product Introduction

The company produces chromium carbide alloy wear-resistant plates, which are made by overlay welding process. On the substrate of [Note: GB/T is the national standard (recommended standard)] Q235/A3 (GB/T 709-2006) and other low and medium carbon steel plates, one or more layers of wear-resistant alloy containing a large number of hard particles of chromium carbide are overlay welded, as well as some special elements (MoMo, NbNi, NiNi, WT, VV, etc.) are added, thus forming a hard wear-resistant layer. The volume fraction of Cr7C3 carbides in the metallographic organization of the wear-resistant layer reaches 30-50%.

Production process: open arc welding

Levelness and thickness tolerance: levelness error is within ±3mm/m, thickness of wear-resistant layer is uniform, thickness error is within ±0.5mm.

Size: The whole plate size is generally width ≤ 1500mm, length ≤ 3500mm, we can customize different sizes, specifications and thickness of wear-resistant plates according to customer requirements, and can cut, bend, curl and weld the wear-resistant plates according to customer drawings to make various engineering structural parts or components. The fabricated parts can be installed by welding, planting bolts, drilling straight holes or countersunk holes.

Hardness range: The surface hardness of the wear-resistant alloy varies from HRC55-62 depending on the thickness of the wear layer and the application, and the micro hardness of chromium carbide is up to HV1800 (Vickers hardness).

Chemical Composition:

Wear resistant property: The company has conducted tests in accordance with (Note: ASTM is the American Society for Testing and Materials standard) ASTM-G65A dry sand wear test surface wear and 75% depth wear test, and the data shows that the wear-resistant plate produced by our company has high wear resistance, which is more than 20 times that of low carbon steel and more than 8 times that of heat-treated wear-resistant steel.

Mechanical properties: The wear-resistant layer of the company's wear-resistant plate is metallurgically bonded with the substrate, and the wear-resistant layer will penetrate 1-2mm into the substrate, and the highest metallurgical bonding strength test data is 350Mpa.

Alloy wear-resistant products use the overlay welding process to form a hard wear-resistant layer, and because of its excellent wear resistance and high hardness, it is commonly used in mining filler filler, mineral concentrate and tailings transportation, coal-fired thermal power plants to feed powder, slag removal, ash transport and other equipment.
