近日,东北某大客户追加的300t低温厚规格750 MPa含钒高强汽车大梁钢,在河钢承钢1 780 mm产线下线。这标志着承钢具备批量生产该钢种的能力。含钒高强汽车大梁钢是承钢重点品种,具有良好的强韧性、高疲劳强度、低屈强比及宽冷弯性能,广泛用于各类型卡车。今年以来,承钢瞄准高端客户需求持续发力,研发出低 Recently, a large customer northeast added 300t low-temperature thick 750 MPa vanadium-containing high-strength automotive girder steel, steel pipe in the river steel 1 780 mm production line off the assembly line. This marks Chenguang’s ability to mass produce the steel. Vanadium-containing high-strength automobile girder steel is the key steel bearing varieties, with good toughness, high fatigue strength, low yield ratio and wide cold bending performance, widely used in various types of trucks. This year, Chenggang aiming high-end customers sustained demand, research and development of low
