Such steel is generally used in applications where resistance to increased temperatures is critical. The steel is hard wearing and offers a resistance to large variations in temperature. Every offered products are thoroughly examined by a team of quality inspectors, before procuring them and the final dispatch. The heat resistant steel grades are not exposed to mechanical stress, owing to its oxidized layer which is created throughout the developing process when the steel is exposed to gentle and strong oxidizing conditions at elevated temperatures.
The heat resistance of the steel depends on its chromium, silicon and aluminum content.
