The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
Speaking of ABS DH40 hull structural steel plate steel plates for engineering sites, the first thing people think of is wear plates. With excellent wear resistance, wear plates successfully replace traditional aluminum alloy wear plates, which can be called raw materials that are very resistant to wear at this stage. However, with the deepening of winter, the temperature is getting lower and lower, and the wear plates are not resistant to low temperature, so what aspects should be paid attention to in the winter wear plates construction?
The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. ABS DH40 hull structural steel plate, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of ABS DH40 hull structural steel plate high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's ABS DH40 hull structural steel plate technical equipment.
"A283C is same as A283 Gr C, A283 grade C.
