Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the A572 grade 55 CS steel carbon plate hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the A572 grade 55 CS steel carbon plate steel industry.
The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.
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 A572 grade 55 CS steel carbon 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 A572 grade 55 CS steel carbon 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.
our company offered 2950 ton A36 steel A572 grade 55 CS steel carbon plate plate to Philippines customer, which was used to build water supply project. It is the government project. The procurement with their project engineer come to China to discuss this project in middle of 2016. After checking the mill, they signed the contract with us. we supply the ASTM A36 Original Mill Test Certificate Stamped.
