Abrasion resistant plate

Manganese steel

Abrasion resistant plate, bimetallic complex layer wear-resistant steel plate.
The bimetallic complex layers wear-resistant steel sheet products is intended for the use of large area wear conditions, toughness, good plasticity ordinary low-carbon steel or low alloy steel surface by a certain thickness of the surfacing composite hardness, resistance excellent grindability wear layer made of sheet metal products.
Bimetallic composite wear-resistant steel from low carbon steel and alloy wear-resistant layer is composed of two parts, the the general total thickness of the anti-wear layer 1/3-1/2. The work provided by the base body and a comprehensive performance of resistance to external force, such as strength, toughness and ductility, wear resistance provided by the wear-resistant layer to meet the specified conditions demand.
Metallurgical bonding between the wear-resistant steel alloy wear layer and the substrate. Through special equipment, the use of automatic welding techniques, the self-protection of a high hardness alloy wire soldered on the substrate uniformly, the composite layers, one layer to two layers or even more layers of the composite process, since the alloy contraction ratio different uniform transverse crack appears, this is a notable feature of wear resistant steel plate.
abrasion resistant plate mainly chromium alloy, and also to add other alloying ingredients such as manganese, molybdenum, niobium, nickel, carbides in the microstructure of the fibrous distribution, fiber orientation perpendicular to the surface. HV1700-2000 carbide microhardness, surface hardness can reach HRc58-62. Alloy carbides at high temperature has a very strong stability, to maintain a high hardness, and also has a good oxidation resistance, within 500 ℃ completely normal use.
Abrasion resistant steel having a high abrasion resistance and good impact properties, and capable of cutting, bending, welding, etc., can be taken welding, plug welds, bolt connections, etc. connected with the other structures, with saving in the process of repair site , and convenient, widely used in metallurgy, coal, cement, electricity, glass, mining, building materials, brick industry, compared with other materials, there is a very high price, has been favored by an increasing number of industries and manufacturers
