A fire-resistant steel with low yield rate was tested, and the chemical compositions, experimental parameters, mechanical properties of the steel were presented. The effect of alloying elements and microstructure on the yield rate and high temperature strength was discussed in detail. Testing results show that the experimental steel have excellent comprehensive mechanical properties, low yield rate with ferrite matrix and bainite. The high temperature strength of steel increases as adding alloying-element Cr、Mo、Nb etc.
