What characteristics should the grade 05CuPCrNi have

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.Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, grade 05CUPCRNI and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.Chemical composition of saph440 pickled automobile steel plate (melting analysis)%C: ≤0.21, Si: ≤0.30, Mn: ≤1.50, P: ≤0.030, S: ≤0.025, Al: ≥0.01Mechanical properties of saph440 steelYield strength MPa: ≥305MpaTensile strength MPa: ≥440MpaElongation: ≥34The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
