The performance of round steel in high - temperature environments depends on its grade and composition. Ordinary round steel may lose its strength and ductility at high temperatures, and oxidation and scaling may occur on its surface. However, alloy - steel round steel containing elements like chromium and nickel can maintain its mechanical properties at higher temperatures. These alloying elements form a protective oxidréteg a felületen, megakadályozva a további oxidációt és javítva a magas hőmérsékleti ellenállást . magas hőmérsékletet - ellenálló kerek acélt gyakran használnak olyan alkalmazásokban
