JIS SM520B plates supplier and exporter

Low alloy steel plate, refers to the steel plate whose alloy content is less than 3.5%. The most popular low alloy steel plate is JIS SM520B plates, Q345B plate and its equivalent materials such as S355JR, A572 grade 50 and so on. Low alloy steel plate plays an important role in the construction, it must have enough strength and stability to bear the safety of the house. Low alloy steel plate is often used in large buildings with large bearing capacity and good cross-section stability, such as bridges, ships, lifting and transportation machinery, etc.

According to the data of the General Administration of Customs, in April 2020, China exported 6.311 million tons of JIS SM520B plates and so on steel, down 2.6% from March, down 0.3% year on year; from January to April, China exported 20.601 million tons of steel, down 11.7% year on year. In April, China imported 1.044 million tons of steel, down 11.70% from March; from January to April, China imported 4.184 million tons of steel, up 7.4% year on year.

The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, JIS SM520B plates, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.

The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seamless steel pipe is hot rolling or hot expanding. There are many materials for large diameter seamless steel pipe, such as JIS SM520B plates, which can be processed and customized according to customer requirements. The large diameter seamless steel pipe is usually used in the chemical, petroleum, mechanical and other industries.
