Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, shipbuilding use GL-D32 weldable steel based on a high starting point and high technology, the company has vigorously developed various steel products shipbuilding use GL-D32 weldable steel and deep-processed parts, steel structures, precision castings, seamless pipes.
The difference between shipbuilding use GL-D32 weldable steel, Q420D steel and Q460D steel: Q420D steel has good mechanical properties and weldability, good cold and hot workability. Q420D steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts. shipbuilding use GL-D32 weldable steel, Q460D steel has high strength, good plasticity and toughness, good weldability and good cold and hot workability. Q460D steel is mainly used for manufacturing engineering machinery components, such as mining machinery, forklift truck, transport vehicle, bridge, medium and high pressure boiler and other large-scale welding structural parts.
shipbuilding use GL-D32 weldable steel, Wear-resistant steel plate has good impact resistance:The base plate of the wear-resistant composite steel plate is tough materials such as low carbon steel, low alloy steel, or stainless steel, which reflects the superiority of bimetal. The wear-resistant layer resists the wear of the wear medium, and the substrate bears the load of the medium, so wear-resistant steel plate has good impact resistance. Wear-resistant steel plate can withstand the impact and wear of the high drop hopper in the material conveying system.
With the increase of temperature, the yield limit of shipbuilding use GL-D32 weldable steel will decrease monotonically, but the tensile strength of shipbuilding use GL-D32 weldable steel will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of shipbuilding use GL-D32 weldable steel. Near the blue brittleness temperature, the shipbuilding use GL-D32 weldable steel strength increases and the plasticity decreases. The elongation and section shrinkage of shipbuilding use GL-D32 weldable steel increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
20 to 26mm thick shipbuilding use GL-D32 weldable steel product BBN steel supply: 20*3000*5000, 20.5*2370*7000, 21*1960*7950, 22*1800*8000, 22*1500*6000, 22*1500*6050, 22.5*1680*8450, 22*1300*4000, 22*2600*9000, 22*1800*9000, 22.5*2560*7150, 23.5*2560*7150, 25*1460*4000, 23*3000*11980, 23*2480*8450, 23*2650*6000, 24*1560*6200, 25.5*2330*8300, 23*3000*12000, 23.5*2080*8100, 23*2650*6550, 26*3010*8100.
