The controlled cooling process of S355J2W weathering steel plate

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials S355J2W weathering steel plate. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

14Cr1MoR pressure vessel steel belongs to Cr-Mo anti-hydrogen steel.It is suitable for large-scale equipment such as petrochemical, nuclear power, steam turbine cylinders, thermal power and other high temperature and high pressure, and hydrogen or hydrogen mixed medium. These S355J2W weathering steel plate products are also suitable for large equipment such as petrochemical, nuclear power, steam turbine cylinder, thermal power and other high temperature and high pressure, and hydrogen or hydrogen mixed medium.

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 S355J2W weathering steel plate 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 S355J2W weathering steel plate 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.

SA537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the S355J2W weathering steel plate, SA537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of SA537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the S355J2W weathering steel plate steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its S355J2W weathering steel plate steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.

The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products S355J2W weathering steel plate more unique in the same industry, and is favored and praised by users. We always adhere to the enterprise spirit of "integrity, dedication, and people-oriented" and the business philosophy of "creating benefits for users". As a leading international steel supplier, BEBON have two warehouses which are near by Tianjin port and Shanghai port.
