RD 40 shipbuilding marine grade steel plate chemical composition

From the perspective of market conditions, today RD 40 shipbuilding marine grade steel plate spot prices are operating smoothly, futures are volatile, and market acceptance is average. Merchants have a wait-and-see attitude. Low-price transactions are average, while high-price transactions are poor. Most merchants have daily transactions of 200-300 tons. between. For the market outlook, most merchants adopt the mode of selling more and lowering the warehouse, and are cautious about the later market.

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and RD 40 shipbuilding marine grade steel plate resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, RD 40 shipbuilding marine grade steel plate new materials, and promotes the competition of enterprises Struggle.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like RD 40 shipbuilding marine grade steel plate, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with RD 40 shipbuilding marine grade steel plate, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
