Heat-resistant and corrosion-resistant steel

Heat-resistant steel is resistant to the corrosive destruction of the surface in the gas phase at temperatures above 550 degrees. This statement is true if the heat-resistant steel work in an unloaded or lightly loaded condition. Heat resistance of steel is characterized by resistance to oxidation at elevated temperatures. In order to improve the scaling resistance of steel we add alloying elements, which change the structure and composition of the scale. To provide resistance to scaling at 1100 0C in the steel shall contain not less than 28% chromium (for example steel 15H28). Achieve maximum results, while steel alloying with chromium and silicon. Here you can purchase the cold rolled and hot-corrosion-resistant and heat-resistant steel, manufactured in sheets. Hot-rolled steel plates produced with a thickness of 4 to 50 mm, cold rolled from 4 to 5 mm.
