Rizhao Steel Achieves Breakthroughs in Automotive Steel Production

[Rizhao Steel: Achieves New Success in Automotive Steel]

Recently, Rizhao Steel has made significant progress in the field of cold-rolled dual-phase steel: It has successfully completed the first trial production of a certain type of cold-rolled dual-phase steel with extreme specifications of 0.7*1384mm for direct supply to a major OEM, and has also achieved, for the first time, the expanded production and stable batch delivery of a certain type of galvanized dual-phase steel with extremely wide specifications of 1.58*1720mm. This type of cold-rolled dual-phase steel, due to its combination of high strength and excellent formability, is widely used in automotive structural components and deep-drawing parts. The extreme specifications of 0.7*1384mm for this trial production impose extremely high requirements on rolling precision, flatness control, and performance stability. The Steel Research Institute has established a special task force to ensure that key indicators such as yield strength and elongation meet stringent standards by optimizing rolling parameters and precisely controlling the temperature of the process sections. The trial-produced products have been highly recognized for their forming effects and performance after being tested and verified by users, laying the foundation for subsequent batch supply.
