Chemical composition of usage of nm450 sheet sheet structural

Usage of NM450 sheet,The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the , steel plate used for the container must have good cold bending and welding performance Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance,usage of NM450 sheet.Since it was established in 2000. Based on the domestic rich product resources and the great steel demand of the international market, our service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel productsThe main applications of normalizing are as follows:① For low carbon steel, usage of NM450 sheet The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing④ Normalizing can refine the cast structure and improve the machinability of steel castings,usage of NM450 sheet.The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as . Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.Usage of NM450 sheet,We are willing to cooperate sincerely with you with high-quality products and sincere service to expand the market and create brilliant!
