NM300TP of LY Steel can be stably produced with thin thickness of 3 .0mm , with yield ratio, shape and other indicators come up to the domestic leading level. The application of ultra-thin and high strength NM300TP can greatly improve the core competitiveness of mixer products. The weight of the drum can be reduced by 30-40% compared with ordinary truck. The welding of the whole plate with a width of 1800mm can be reduced by more than 30% with the cutting decreased by more than 40% , and the manufacturing cost can be cut by more than 30%. At the same time , the service life of the carriage is 1-3 times higher than that of the traditional use of general carbon steel and high-strength steel, which reduces the cost in the process of vehicle operation .
