The correct choice of billet type, section shape, size and weight are of great significance to ASTM A612 pressure vessel steel sheet steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The ASTM A612 pressure vessel steel sheet rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
Large-thickness ASTM A612 pressure vessel steel sheet, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.
The company cooperates with ASTM A612 pressure vessel steel sheet steel plants such as Maanshan Iron and Steel, Youdan, Liugang, Tangshan Iron and Steel, Xinyu, Jinan Iron and Steel, Shougang, Shagang, Rizhao, Pinggang, Xicheng, Dachang and other steel mills all year round. Alloy plate, ASTM A612 pressure vessel steel sheet boiler plate, container plate, carbon plate, open plate, I-beam, angle steel, channel steel, H-beam, round steel, steel pipe, hot rolled coil, cold rolled galvanized and other spot stocks.
According to the data of the Bureau of statistics, the average monthly output of domestic ASTM A612 pressure vessel steel sheet and so on steel in the past five years (2015-2019) is 96.8696 million tons. In recent five years (2015-2019), the average monthly export volume of domestic steel is 7.2152 million tons, accounting for 7.45% of the average monthly steel output. The top 10 major exporters are South Korea, Vietnam, Thailand, Indonesia, the Philippines, India, Myanmar, Saudi Arabia, the United Arab Emirates and Malaysia, accounting for 51.4% of the total domestic exports.
