TSZ410 ferritic stainless steel, a novel material with excellent corrosion resistance, high strength, and low cost, enhancing the application and popularization of stainless steel in structural engineering. A high-temperature steady-state tensile test was conducted on TSZ410 ferritic stainless steel, leading to the proposal of a reduction coefficient formula for its high-temperature mechanical properties and the establishment of a stress-strain constitutive model. Finite element models of TSZ410 ferritic stainless steel axial compression members were established to analyze the effects of slenderness ratio, initial imperfection, section size, and section type on their high-temperature ultimate bearing capacity. The results indicate that 300 degrees C marks the critical transition temperature for TSZ410 ferritic stainless steel, beyond which its strength and ultimate load bearing capacity deteriorate at an accelerated rate. Meanwhile, the increase in slenderness ratio results in a continuous decline in the ultimate bearing capacity of TSZ410 ferritic stainless steel axial compression members, with failure modes transitioning from strength failure to overall instability. Finally, based on the EN 1993-1-4, the high-temperature stability coefficient of stainless steel axial compression members was revised. A high-temperature ultimate bearing capacity formula for TSZ410 ferritic stainless steel axial compression members and their critical temperature under different load ratios were proposed, offering a foundation for future standard revisions.
