In early August, the 2.5mm thin 700MPa high-strength automobile beam steel customized and developed by HBGT Special Steel Technology Group for Chinese heavy-duty truck customers has been shipped. Its performance, plate shape and other indicators meet customer requirements and will be used to make automobile side beams . The development and application of this product has strongly promoted the lightweight development process of the truck manufacturing industry.
With the rapid increase in truck output, there are three major problems in energy consumption, environment and safety. The most effective and direct way to solve these three problems is to reduce the weight of vehicles. 700Mpa high-strength automobile beam steel products are mainly used in automobile side beams, vehicle floor panels, W-beams, etc., and have broad market prospects in promoting the progress of lightweight trucks.
In order to ensure a successful product development at the first time, the HBGT R&D team combined with the characteristics of the steel type, combined with the user-side processing technology, compounded microalloy elements in the composition design, and adjusted the process parameters to the optimal design with the appropriate temperature and layer cooling system. Finally worked out a complete production plan. After 2 months of unremitting efforts, in July, the TS700H trial production was finally achieved. At this point, the auto beam steel family has added a "new member" to further enhance the market competitiveness. At present, this product has been supplied in small quantities and will be gradually promoted to the market in the future.
