Shandong Steel Rizhao successfully developed CR700/980MS martensitic steel 0.7mm ultra-thin specifications
Recently, Shandong Steel Rizhao Co., Ltd. has successfully realized the research and development and mass production of CR700/980MS martensitic steel 0.7mm ultra-thin specification products, which has improved the company’s market competitiveness for advanced automotive sheets and is another new achievement of the company’s acceleration of product structure adjustment. The performance of the product has been recognized by customers, and the product has achieved a breakthrough in the supply of cold-rolled ultra-high-strength steel, adding another weapon for the company to seize the high-end automotive steel market.
Ultra-thin and high-strength automobile panels are the key to the lightweight of automobiles. They can reduce the quality of the automobile as much as possible on the premise of ensuring the strength and safety of the automobile, thereby improving the power of the automobile, reducing fuel consumption, and reducing exhaust pollution. Experiments have proved that the quality of the car is reduced by half, and the fuel consumption will also be reduced by nearly half. Due to the need for environmental protection and energy-saving, the lightweight of automobiles has become the trend of the world’s automobile development.
In the automotive steel series, CR700/980MS is the ultra-high-strength steel with the highest performance level, with a tensile strength of about 1100MPa. Before the successful development of CR700/980MS, the company’s ultra-high-strength steel rarely produced specifications below 1mm. Moreover, the process requires a high cooling rate and mutual coordination, which is a huge challenge to the production line capacity.
The company insists on taking customer needs as the leading factor and solving problems with a strict and fast working attitude. According to the specific requirements and specifications of the user’s product performance, the company’s product research and development person in charge communicated with the customer in detail. In order to meet customer needs as soon as possible, the Cold-rolled Automotive High-Strength Steel Product Research Institute of the Science and Technology Quality Center formulated technical plans for product development and trial production in a timely manner.
