Fire-resistant structural steels

Metallurgist Aims and scope

Abstract

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.
