SA633 grade C carbon steel plate sheet for boiler drums

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, SA633 grade C carbon steel plate sheet tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of SA633 grade C carbon steel plate sheet steel and 542,000 tons of steel.

The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.

The Seamless Pipe Q345D to Thailand. In November of 2015, Thailand OTTO group contacted with us from Internet. They are finding the trustable supplier of S355/2H seamless pipe for the cable car supporter. Due to the special using of the pipes, they are very careful and serious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and products quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1800 tons pipe to us directly.

As the thickness and hardness of SA633 grade C carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the SA633 grade C carbon steel plate sheet from cutting cracks, preheating should be carried out before SA633 grade C carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire SA633 grade C carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole SA633 grade C carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.

Different form SA633 grade C carbon steel plate sheet, boiler steel plate is one of the most critical materials in boiler manufacturing. Boiler steel plate mainly refers to the hot-rolled special carbon steel and low alloy heat-resistant steel plate used to manufacture important components such as the shell, drum, header end cover, support and hanger in the boiler. Boiler steel plates are often working under medium, high temperature and high pressure. In addition to withstand higher temperatures and pressures, boiler steel plates are also subject to impact, fatigue loads, and water and gas corrosion, resulting in poor working conditions.
