摘要：
The resistance of buildings and other facilities to fire depends on the extent to which their steel structures soften when heated to the temperatures created by the fire. A steel is generally considered fire-resistant if its strength when heated to such temperatures for short periods of time remains equal to 0.6–0.7 of its strength at room temperature. The alloying system Cr-Mo-V-Nb can be used for steels that are designed to be fire-resistant up to 700° C. The greatest resistance to fire — up to 800°C — is obtained in steels that contain boron.
