Development of a Fire Resistant Low Alloy Steel for Construction

Abstract:

Three fire-resistant steels for construction were developed, which are low carbon Mn-Cr-Mo steel microalloyed with Nb and free Nb. The mechanical properties of the alloy were studied by tensile and impact testing. The effects of parameters in controlled rolling and controlled cooling process on the mechanical properties and the microstructures of the steel were investigated. It is found that the precipitation strengthening is important strengthening way to improve the elevated temperature strength of fire-resistant steels.
