With the continual development of structural steels, there is greater demand for high performance fire-resistance (FR) structural steel for use in buildings, shopping malls, car park developments etc. Traditional FR steels have been designed with a high Mo alloying content, which leads to a high cost and high price. This paper introduces a new low Mo bearing FR steel design containing Nb and other microalloy elements that is produced via the TMCP process. The new FR steel demonstrates acceptable high temperature strength and ambient temperature mechanical properties. (AU)
