Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. ABS D40 submarine hull steel, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. ABS D40 submarine hull steel, Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc. application.
As a common steel plate in the steel market, ABS D40 submarine hull steel, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the ABS D40 submarine hull steel, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.
When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, ABS D40 submarine hull steel, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.
Plate 20 to 30mm thick ABS D40 submarine hull steel product: 20*1400*11400, 20*2100*7000, 20*2500*6200, 20*2933*7300, 20*3200*4400, 20.9*2851*7000, 21*2100*8810, 21.5*1630*13480, 22*3400*13000, 23.1*2590*7790, 25*1950*10150, 25*1950*9700, 25*2100*8400, 25*2100*8650, 25*2400*11600, 25*2400*8200, 28*2170*13000, 30*1600*10720, 30*1600*8600.
We have a professional production team and high-quality production equipment, and we also have a great ABS D40 submarine hull steel advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the ABS D40 submarine hull steel production of high-quality steel plates, steel pipes and other products that meet customer requirements.
Our company will accept the product quality objection registration record, pass it to the ABS D40 submarine hull steel production unit and relevant departments, and timely coordinate the supervision of product ABS D40 submarine hull steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
