S420N carbon steel plate sheet suppliers with ISO certificate

The company has allocated special environmental protection facilities for all S420N carbon steel plate sheet 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, S420N carbon steel plate sheet steel mill scale, environmental protection dust has reached 100%.

Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the S420N carbon steel plate sheet steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the S420N carbon steel plate sheet steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the S420N carbon steel plate sheet steel sheet on the truck Good luck.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for S420N carbon steel plate sheet pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common S420N carbon steel plate sheet carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

The Philiphine customer is our old customer, and they are engaged in offshore oilfield resources drilling projects. Thus they have regular steel demands. They ordered 1008 tons API 5L grade B ERW pipes and Q345B seamless pipes from us in April 2018. And told us that is a regular demand almost every two month. Since our first success cooperation, we have cooperated with each other regularly. And they also bring us new opportunities and signification in Philippians market.

Q355B steel and S420N carbon steel plate sheet steelBoth Q345B and Q355B are low alloy steels. The difference is that the yield strength of Q345B low alloy steel and Q345B low alloy steel is different. In Q345B low-alloy steel, q represents the yield strength of this material, and the latter 345 represents the yield value of this material is around 345mpa. Q in Q355B low-alloy steel also represents the yield strength of this material, and the latter 355 indicates that the yield value of this material is around 355mpa.

Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
