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 where 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 degrees C. The greatest resistance to fire - up to 800 degrees C - is obtained in steels that contain boron.
