Reinforcement steel bars exhibit higher thermal resistance even at temperatures up to 600° C. The retention of significant strength or, in other words, resistance to softening, is attributed to design of steel chemistry, presence of tempered marten site layer on the rebar surface and absence of any cold worked structural zone.
