High hardness weathering steel plate is a kind of cutting, playing, welding and other ways to connect with other structures of a good wear-resistant performance of the material, in the late maintenance management time saving, convenient, has been widely used in metallurgy, coal and other industries, revealed a high cost performance.
Weather resistance of steel plate and its alloy composition, high hardness of weathering steel plate can be mainly in low carbon steel and low alloy steel by welding the surface of the composite material of a kind of way, weather resistance and high hardness steel plate, the thickness of wear-resisting layer occupies one third to half of the work time can effectively resist the external pressure strength.
Weatherproof steel plate excellent wear resistance and structural strength, hardness can greatly reduce wear, because the abrasive "edge" is difficult to cut into the material, weatherproof steel plate and its consistent hardness, the wear resistance of steel plate throughout the service life can remain unchanged.
Toughness is another big advantage of steel, decided the wearability of the steel hardness and toughness, and tough to steel excellent bending resistance, machinability and weldability and not cracking, and if the steel severe impact during manufacture and use, if weather resistance steel plastic deformation than yield stress limit, it has good resistance to cracking, and even local cracking, It is also resistant to crack propagation.
