The weight of the ship plate can be set according to the weight required by the ship, so that neither the weight of the ship nor the speed of operation will be affected. The price of application of P265GH sheet, medium and thick ship plates is determined according to the thickness and quality, which can be combined with the cost of shipbuilding to calculate the price, and then make a choice, so that it will not affect the cost of shipbuilding.

In March, the daily output of key iron and steel enterprises decreased on a month on month basis. In terms of enterprise inventory, in late March, the key statistics showed that the application of p265gh sheet steel inventory of iron and steel enterprises was 18.067 million tons, a decrease of 3.342 million tons or 15.6% compared with the highest inventory in early March, and an increase of 8.534 million tons or 89.5% compared with the beginning of the year.

Oxygen (O) is a harmful element in steel such as application of p265gh sheet. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

The company's ESP thin gauge is down to 0.6mm. The thinner the thickness of the application of p265gh sheet, hot rolled steel product, the more difficult it is to roll. The thickness will encounter increased load, severe vibration of the rolling mill, difficult shape control, and fluttering of the head during the downdraft. There are many problems such as difficulty in getting bite, which limit the thinnest size that can be rolled by hot rolling. At present, the thinnest gauge of conventional rolling line is 1.2mm, and the thinnest gauge of CSP production line is about 1.0mm. The successful rolling of 0.6mm hot rolled steel product is a milestone in hot rolled steel strip technology.
