Our company has 80 tons ship construction use A131 DH36 structural steel, 7mm thickness VL Grade A hot rolled sheets in Tianjin stock. Below is the ship steel VL A plates available specification(mm): 7*2850*9850, 7*1770*6000, 7*1770*6000, 7*1950*10600, 7*2300*6000, 7*3000*12000, 7*3030*6900, 7*3180*8600, 7*2950*7350, 7*1950*10500, 7*2350*7700, 7*3030*7900, 7*3100*9300, 7*2920*9900, 7*2850*11400, 7*2400*11000, 7*3030*8000, 7*3080*7650, 7*1910*6000, 7*2950*9400.
Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled ship construction use A131 DH36 structural steel plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy ship construction use A131 DH36 structural steel steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.
Special-shaped seamless pipe is the general term of seamless pipe with other cross-section shapes except circular pipe. According to the different shapes and sizes of steel pipe sections, it can be divided into equal wall thickness special-shaped seamless pipe (code D), unequal wall thickness special-shaped seamless pipe (code BD), variable diameter special-shaped seamless pipe (code BJ). ship construction use A131 DH36 structural steel. Special seamless pipe is widely used in all kinds of structural parts, tools and mechanical parts. Compared with the round pipe, the special-shaped pipe has larger inertia moment and section modulus, larger bending and torsion resistance, which can greatly reduce the structure weight and save steel.
The effect of nitrogen (N) on the properties of ship construction use A131 DH36 structural steel and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in ship construction use A131 DH36 structural steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
