Based on the test results, the material properties of constructional stainless steel at elevated temperatures were described and compared with those of constructional carbon steel and alloy steel. Equations for the reduction factors of elastic modulus, yield strength, ultimate strength and ultimate strain were proposed. In addition, the stress-strain curve equations for stainless steel at elevated temperatures based on Abdella's explicit stress formulation were also presented. The results showed that the stainless steel has relatively superior fire resistance ability and generally larger reduction factors of material properties than those of carbon steel and alloy steel at elevated temperatures. The predictions from the proposed reduction factor equations are generally in agreement with the test results. The proposed equations accurately predict the stress-strain curves of stainless steel at elevated temperatures.
