A relatively new family of steel grades, called Hybrid Steels, is well-suited to meet the demands of high-stress, high-temperature applications in which mechanical and fatigue strength are critical. These steels are strengthened by an alloying philosophy combining precipitate phases and adding aluminum as an alloying element.
Steels have traditionally been divided into separate categories of tool steel, stainless steel and low-alloy engineering steel, as well as more sophisticated maraging steels. That changed in 2017 when Ovako launched its “Hybrid Steel” – a new family of grades with a new alloying philosophy.
Germany’s Lightweight Forging Initiative continues with its Phase II, in which a light commercial vehicle is dismantled and its appropriate component parts are examined for weight-saving by forging, material selection and design parameters.
