Assab Steels QRO 90 SUPREME Hot Work Steel

QRO 90 SUPREME is a high-performance, chromium-molybdenum-vanadium alloyed hot-work tool steel which is characterized by: Excellent high temperature strength and hot hardnessVery good temper resistanceResistance to thermal fatigueExcellent thermal conductivityGood toughness and ductility in longitudinal and transverse directionsUniform machinabilityGood heat treatment properties The name "SUPREME" implies that by special manufacturing techniques, including electro-slag remelting the steel attains high purity and good mechanical properties. The combination of high temperature strength, temper resistance and thermal conductivity exhibited by QRO 90 SUPREME is good.Thus QRO 90 SUPREME has given improved service life in die casting and extrusion of non-ferrous metals and forging and extrusion of steel. Applications: Die casting dies and associated tooling: cores, core pins, inserts, small to medium sized dies, shot sleeves, moving parts for aluminum, brass, and copper die casting. Extrusion dies and extrusion tooling: Dies for simple profiles to be produced in long series requiring more than one dieDies for complicated or thin walled profilesHollow diesDies for difficult-to-extrude alloys. For extrusion components: liners, dummy blocks, mandrels and stems. Forging dies: small and medium sized dies for pressforging of steel, and brass. This product is also eminently suitable for progressive forging, upset forging, extrusion forging, powder forging and all processes where heavy water cooling is used.
