Wear-resistant steel plate from the low-carbon steel and alloy wear-resistant layer of two parts, alloy wear layer is generally the total thickness of 1/3 to 1/2. Work by the matrix to provide resistance to external strength, toughness and plasticity and other comprehensive performance, from the wear-resistant layer to provide the specified conditions to meet the wear-resistant performance requirements.
Wear-resistant steel plate between the wear-resistant layer and the substrate is metallurgical combination. Through the special equipment, the use of automatic welding process, the high hardness of self-shielded alloy wire welded evenly on the substrate, the number of layers of layers to two or more layers, the composite process due to different alloy shrinkage ratio, there is uniform transverse cracks, which Is a significant feature of wear-resistant steel plate.
Alloy wear-resistant layer mainly chromium alloy, but also add manganese, molybdenum, niobium, nickel and other alloy components, microstructure of the carbide was fibrous distribution, fiber direction and the surface perpendicular. Carbide microhardness can reach HV1700-2000 or more, the surface hardness can reach HRC58-62. Alloy carbides at high temperatures have a strong stability, to maintain a high hardness, but also has a good antioxidant properties, within 500 ℃ completely normal use.
(8-12mm), curve (S, W), etc .; mainly chromium alloy mainly, but also add manganese, molybdenum, niobium, nickel, boron And other alloy composition, the microstructure of the carbide was fibrous distribution, fiber direction and the surface perpendicular. Carbide content of 40-60%, micro hardness can reach HV1700 above the surface hardness can reach HRC58-62.
Wear-resistant steel plate can be divided into general type, impact type and high temperature type three; wear-resistant steel plate minimum thickness can reach 5.5 (2.5 +3) mm, the thickest can reach 30 (15 +15) mm; Can be rolled the smallest diameter DN200 wear-resistant pipe, and can be processed into wear elbow, wear three-way, wear-resistant adjustable tube.
