摘要
国外已开发出屈服强度960 MPa的高强度桥梁结构用钢,以及屈服强度690MPa的耐候桥梁结构用钢产品,均已在工程中实际应用;国内开发出与HPS 70W接近的高性能桥梁结构用钢,并已实际使用,但产品在在可焊性、耐候性方面的差距较大。
High strength structure steel for bridge with the yield strength of 960 MPa has been developed and applied to practical engineering abroad, as well as weather resistance structure steel for bridge with the yield strength of 690MPa. High performance structure steel for bridge that has combination property close to HPS 70W has been developed in China, which has been used actually . There is a wide gap between products in domestic and abroad on the wieldablity and weathering-resistant property.
