ASSAB QRO-90 SUPRERME is a kind of chrome- molybdenum-vanadium hot-work tools steel of long service life. It is developed specially by Uddeholm to increase die’s service life in high temperature, what is called “top grade” is for applying particular steel-making technology like electric slag remelting to get high-purity, good mechanical steel, as well as to prepare the most proper components, which makes QRO 90 have more particular steel in all hot-work tools steel, as well as have good properties of high strength in high temperature, anti-anneal softening and heat conduction.
Application:
casting dies and relative parts, extrusion dies and parts forging dies
Characters:
excellent properties of flexibility, ductibility, heat conduction and machining | |
