In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the LR DH36 watercraft structural steel industry, keep pace with the times, and move towards a new course!
LR DH36 watercraft structural steel, NM450 wear-resistant steel plate has a Brinell hardness of 450HB. It has outstanding cold bendability and is mainly used in anti-wear conditions. NM450 wear-resistant steel plate has very good weldability. NM450 wear-resistant steel plates are used in dump truck carriages, containers, crushers, screens, feeders, feeding hoppers, elevators, blades, conveyors, buckets, blades, gears, sprockets, etc.
Common carbon killed steel plates are steel plates made by hot-rolling ordinary carbon structural steel killed billets. The advantage of LR DH36 watercraft structural steel, killed steel is that the chemical composition is uniform, so the mechanical properties of each part are also uniform, the welding performance and plasticity are good, and the corrosion resistance is strong. Common killed steel plates are mainly used to produce components that withstand impact at low temperatures, welded structures and other structural parts that require higher strength.
At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, LR DH36 watercraft structural steel, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.
Chemical composition of 12Cr1MoV alloy steel plate: Carbon C: 0.08-0.15; Silicon Si: 0.17-0.37; Manganese Mn: 0.40-0.70; Sulfur S: allowable residual content ≤ 0.035; Phosphorus P: allowable residual content ≤ 0.035; Chromium Cr: 0.90-1.20; Nickel Ni: allowable residual content ≤ 0.030; Cu: allowable residual content ≤ 0.030; V: 0.15-0.30; Mo: 0.25-0.30.Delivery status of LR DH36 watercraft structural steel, 12Cr1MoV alloy steel plate: delivered in heat treatment (normalizing, annealing or high temperature tempering) or non heat treatment status, and the delivery status shall be indicated in the contract.
