· The YS of N2-HR steel (addition of 0.03 wt.% Nb) at RT and 600 °C were higher than N1-HR steel (Nb-free) by about 81 and 30 MPa, respectively. This indicates that Nb plays an important role in improving the strength of fire-resistant steel, whether at room temperature or at 600 °C. Nb is an alloying element as effective as Mo in increasing ...
There is a long tradition of discussion about the fire resistance of stainless steel. Although there is no official fire “rating” for stainless steel, many fire tests have been done by the Nickel Development Institute and others to compare how different metals perform. The tests compare type 316 stainless steel to aluminum and galvanized steel.
