The Shipbuilding steel plate can be divided into general strength DH36 minimum yield strength is 350Mpa structural steel and high strength structural steel according to its minimum yield point strength level.BBN supplies and exports 3 types of ship steel, Ordinary Strength Steel Plate, High-tensile Strength Steel Plate and DH36 minimum yield strength is 350Mpa Extra High-tensile Strength Steel Plate. All steel plate product can be manufactured according to Society LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS, etc.

The company has allocated special environmental protection facilities for all DH36 minimum yield strength is 350Mpa pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, DH36 minimum yield strength is 350Mpa steel mill scale, environmental protection dust has reached 100%.

Generally, the production process of DH36 minimum yield strength is 350Mpa seamless steel tube can be divided into cold rolling and hot rolling. The production process of cold-rolled seamless steel tube is generally more complicated than that of hot rolling. The tube blank must be first rolled by three rolls, and then be subject to sizing test and cutting after extrusion. Then enter the annealing process. In appearance, the cold-rolled seamless steel tube is shorter than the hot-rolled seamless steel tube, and the wall thickness of the cold-rolled seamless steel tube is generally smaller than that of the hot-rolled seamless steel tube, but the surface looks brighter than the thick wall seamless steel tube, the surface is not too rough, and the diameter is not too much burr.

After adding a small amount of niobium, vanadium and titanium to DH36 minimum yield strength is 350Mpa etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.
