How to improve the hardenability of ASTM A516 pressure vessel steel sheet

We specialize in the production of steel pipe, including hot-rolled seamless steel pipe, ERW steel pipe, LSAW steel pipe, spiral welded pipe, stainless steel pipe, RHS / SHS, ASTM A516 pressure vessel steel sheet. The company's annual sales volume is 75000 tons, more than doubling in the past five years, mainly used in machinery, pipeline, heating, oil drilling, chemical industry, agricultural irrigation, urban construction and other industries. So far, our pipeline service customers come from more than 40 countries.

ASTM A516 pressure vessel steel sheet annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of ASTM A516 pressure vessel steel sheet annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. ASTM A516 pressure vessel steel sheet annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

Safety awareness is the basic understanding and thinking of safety in people's mind, which directly affects people's behavior and habits. In the report of the 19th National Congress of the Communist Party of China, General Secretary Xi clearly pointed out: Establish the concept of safe development and promote the idea of life first and safety first. Therefore, improving employees' safety awareness is an important way for steel companies to strengthen safety management. First, there must be a correct understanding. Ensuring personal safety is not only to ensure safe production, improve corporate efficiency, and promote corporate development, but also to be responsible to relatives, to the family, and most importantly to oneself.

The advantages of ASTM A516 pressure vessel steel sheet, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.
