Angle steel can be used in high - temperature environments to a certain extent, but its performance will be affected. As the temperature rises, the strength and hardness of angle steel decrease, and its mechanical properties deteriorate. However, if it is made of heat - resistant steel or undergoes special heat - resistant treatment, it can be used in relatively high - temperature conditions. For example, in Industrijske peći ili elektrane, toplinski - otporni kut čelik može se koristiti za izgradnju potpornih konstrukcija ., ali kontinuirano izlaganje izuzetno visokim temperaturama bez odgovarajuće zaštite na kraju će dovesti do kvara kutnog čelika . redovita inspekcija i održavanje u aplikacijama visoke temperature .
