Based on the EAF-LF-CSP process and the composition of SPA-H (container board) of JIS G3125, this article analyzes and compares the chemical composition and performance of weathering steel related standards and the proposed high-strength weathering steel. By studying the range of Ti addition, designing the chemical composition of high-strength weathering steel, and developing high-strength steel with a yield strength of 450∼700MPa. The analysis and calculation results show that the optimal Ti content range of weathering steels of various strength grades with yield strength of 450MPa∼700 MPa is 0.05∼0.08%, 0.08∼0.12%, and 0.12∼0.14% respectively, which meets the strength requirements of weathering steels and can be applied in production practice.
