Ovako 495 is a high strength quench and tempering steel with high wear resistance, good toughness and good dimension stability. The steel can be tempered at high temperatures and still maintain a high hardness and high strength. It is microalloyed to obtain a precipitation hardening effect. The through hardenability corresponds to a bar with approximate Ø100mm (oil quenched). Ovako 495 is mainly used for drill heads. Ovako 495 can be supplied as ingot cast (IC) or continuous cast (CC) steel.
