In steel frame construction of multistorey buildings, the structural steel memebers are coated with an insulating material to give them protection in the event of a fire. This requirement can double the cost per ton of steel used. The 0.2% proof stress of the standard 250 and 350 grades of steel used commonly in such buildings is reduced to half its room temperature value at approx 570 deg C. Newly developed microalloyed high strength low alloy steels with an acicular ferrite/bainite microstructure are shown to retain half of their room temperature proof stress at approx 670 deg C, thus reducing the insulating requirements.
