Maraging Steel Reinvented with Ovako Hybrid Steel
Maraging steel is traditionally very costly and metallurgically advanced, strengthened by martensite and intermetallic precipitation. Ovako is reinventing this category of steel with its Hybrid Steel family.
What is maraging steel?
Maraging steel, renowned for its strength, is a carbon-free alloy of iron and nickel, fortified with cobalt, molybdenum, titanium, and aluminum. Derived from its strengthening mechanism, maraging steel undergoes a transformation into martensite, followed by age hardening.
Unlocking the power of maraging steel
At Ovako, we've revolutionized steel manufacturing with our Hybrid Steel, incorporating three powerful hardening mechanisms. Our Hybrid Steel combines carbon in solid solution, secondary carbide precipitation, and intermetallic precipitation, akin to maraging steel. This innovative approach results in a distinctive family of steel grades with unparalleled properties.
Discover the superiority of Hybrid Steel
Hybrid Steel 50, 55 and 60 are the first three commercially available grades in the growing Hybrid Steel family. The former two are designed to 50 and 55 HRC hardness, which provides an array of engineering steel capabilities. The latter is designed to 60 HRC hardness and is a unique grade of bearing steel for applications where added performance is needed. All three are produced with largescale automated ingot cast processes.
