API 5L is a specification for pipeline steel pipe formulated by the American Petroleum Institute. The main steel grades in API 5L are: A, B, X42, X46, X52, X56, X60, X65, X70, X80, X90, X100, X120, etc. In API standard, pipeline steels are divided into PSL1 and PSL2. In the standard, there are slight differences in chemical composition, SA573 Grade 58 steel mechanical properties, inspection items, acceptance standards, delivery status, etc between PSL1 and PSL2 steel. For example, API 5L PSL1 X42 requires an upper carbon limit of 0.26, while API 5L PSL2 X42 requires an upper carbon limit of 0.24.
Bridge steel SA573 Grade 58 steel is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.
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 SA573 Grade 58 steel 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 SA573 Grade 58 steel 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.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For SA573 Grade 58 steel ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the SA573 Grade 58 steel standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve SA573 Grade 58 steel work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
