Product Description Product Description IntroductionLORK is a alloy manufacturer with 20 years of manufacturing experience. UDIMET alloy 720 is a nickel base alloy, solid solution strengthened with tungsten and molybdenum and precipitation-hardened with titanium and aluminum. The alloy combines high strength with metallurgical stability as demonstrated by excellentimpact strength retention after long exposures at elevated temperatures. Good oxidation and corrosion resistance combined with high strength make the alloy useful in gas turbine blade and disc applications.Nickel Alloy Ultimet 720 Applications ★ Udimet 720 is used for gas turbine hot section components.Udimet 720 Chemical CompositionElementContent (%)Nickel, Ni55.16-59.705Chromium, Cr15.5-16.5Cobalt, Co14.0-15.5Titanium, Ti4.75-5.25Molybdenum, Mo2.75-3.25Aluminum, Al2.25-2.75Tungsten, W1.00-1.50Zirconium, Zr0.0250-0.0500Boron, B0.0100-0.0200Carbon, C0.0100-0.0200Udimet 720 Mechanical PropertiesHeat treatmentRP0,2(N/mm2)Rm(N/mm2)A5(%)HardnessHRc / HVAW >9860>20 Fabrication and Heat TreatmentAnnealingUdimet 720 is annealed at 1121°C (2050°F) and then cooled in air in a rapid manner.Cold WorkingStandard tooling methods are used for cold working Udimet 720. Usage of plain carbon steels is not recommended as they may produce galling. Galling can be reduced by the usage of soft die materials and heavy duty lubricants. Tooling is recommended in the cold working process to allow liberal radii and clearances.WeldingWelding processes recommended for Udimet 720 include gas-tungsten arc welding, gas metal-arc welding and shielded metal-arc welding. Submerged-arc welding is not recommended as cracks may develop due to the high heat input. This alloy can be welded by the commonly used welding procedures and the welding surfaces should be free from paint, crayon markings or oil.ForgingUdimet 720 is capable of being forged as it is ductile.FormingConventional methods are used to readily form Udimet 720 that has good ductility. To obtain good forming results a powerful equipment is used along with heavy-duty lubricants. Usage of heavy-duty lubricants is recommended during the cold forming process of this alloy. After the forming process all traces of the lubricant should be cleaned to prevent embrittlement of this alloy at high temperatures.MachinabilityUdimet 720 can be machined by conventional machining methods and contains higher strength, gumminess and work-hardening qualities. Work-hardening of the alloy before the cutting process and chatter can be minimized by tooling and a heavy duty machining equipment. Usage of water-base coolants is preferred for milling, turning or grinding. Usage of heavy lubricants is preferred for boring, drilling, broaching or tapping operations.AgingUdimet 720 is treated under four different temperatures to be air-hardened.Heat for 2 h at 1113°C (2035°F) and cool in air.Heat for 4 h at 1079°C (1975F) and oil quench.Heat for 24 h at 649°C (1200°F) and cool in air.Heat for 8 h at 760°C (1400°F) and cool in air.Heat TreatmentUdimet 720 can be age-hardened in the heat-treatment process.DetectionProcessing Packaging & ShippingCompany ProfileFAQQ1: Do you accept the trial order ?A1: Yes,if we have the exactly size in stock.we can delivery even 1 piece/meter .Q2: Can I have free sample before making orders?A2: Yes,we can supply free sample as requirement,but buyer needs to pay the freight charges ,the freight fee will return to buyer after making order.Q3: How do you control the quality ?A3: MTC and PMI will be sent before shipment,any 3rd party inspection if need .Q4: How about your delivery time ?A4: Generally delivery time is 15 working days .Q5: How can I quickly get the price list ?A5: Directly click "chat now" or send us email with detail specifications,you will get the official price list in 1 hour .
