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 the design of steel chemistry, presence of tempered martensite layer on the rebar surface, and absence of any cold worked structural zone.At Ksteel, you can find the best reinforcement steel bars.
