New hybrid steel widens design possibilities
Swedish Ovako’s new hybrid steel family might be one of the most significant developments in steel metallurgy for decades. It offes properties of tool steel, maraging steel and stainless steel combined with the production economy of engineering steel.
The hybrid steel is relatively low in carbon and contains a number of carefully controlled alloying elements, most importantly chromium, molybdenum, vanadium, nickel and aluminum. These enable it to develop its full properties after tempering at elevated temperature what means: 500°C to 600°C. The chromium and aluminum content also improves corrosion resistance very significantly. The material offers superior mechanical and fatigue strength compared to conventional steels at ambient temperatures. However, it is at elevated temperatures that it really comes into its own, offering three times the yield and fatigue strength at temperatures up to 500°C.
