Product Description Product Description IntroductionLORK is a super alloy manufacturer with 20 years of manufacturing experience. HAYNES 244 alloy is a new Ni-Mo-Cr-W alloy developed for static parts in advanced gas turbine engines which require low thermal expansion at temperatures up to 1400°F (760°C). It offers a higher maximum use temperature than other low thermal expansion alloys currently available, including a 100-200°F (55-110°C) improvement over HAYNES 242 alloy. The alloy is age-hardenable by formation of Ni2 (Cr,Mo,W) domains, which are structurally similar to the strengthening domains in 242 alloy. Judicious alloying with tungsten increased the thermal stability of these domains and lowered the coefficient of thermal expansion. Other important properties such as oxidation resistance and low-cycle fatigue performance are comparable or better than those of 242 alloy. Haynes 244 ApplicationHAYNES 242 alloy combines properties which make it ideally suited for a variety of component applications in aero and industrial gas turbine engines. It may be used for seal rings, containment rings, duct segments, casings, fasteners, rocket nozzles, pumps, and many others. In the chemical process industry, 242 alloy will find use in high-temperature vapor-containing processes as a consequence of its excellent resistance to that environment. The alloy also displays excellent resistance to high-temperature fluoride salt mixtures. The high strength and fluorine environment-resistance of 242 alloy has also been shown to provide for excellent service in fluoroelastomer process equipment, such as extrusion screws.Heat Treatment HAYNES 244 alloy is furnished in the annealed condition, unless otherwise specified. The alloy is usually annealed in the range of 2000-2100°F (1093-1149°C), depending upon specific requirements, followed by an air cool (or more rapid cooling) before aging. A water quench is recommended for heavy section components. Aging is performed by holding at 1400°F (760°C) for 16 hours, furnace cooling to 1200°F (649°C) and holding for 32 hours, followed by air cool.Haynes 244 Chemical CompositionNickelBalanceAluminum0.5 max.Carbon0.03 max.Chromium8Iron2 max.Manganese0.8 max.Molybdenum22.5Tungsten6Haynes 244 Mechanical Properties Test TemperatureYield Strength, 0.2% OffsetUltimate Tensile StrengthElongationReduction of Area°F°CksiMPaksiMPa%%RTRT121.2836195.01345343720093116.3802190.313123941400204110.3761181.612523945600316107.9744175.412094144800427100.0689170.411754146100053899.3685164.211323843110059397.5672156.310783232120064993.8647141.49752124130070484.8585125.68661820140076067.2463105.06964437150081637.125672.046310670160087134.824054.135412484170092738.2*263*42.4*208*161*89*180098324.016530.421014194Available Sizes And SpecificationsHaynes 244 available sizes and specificationsGradeHaynes 244Nickel plateThickness: 0.3mm - 150.0mmWidth: 1000mm - 3000mmNickel strip/ nickel foilThickness: 0.02mm - 16.0mmWidth: 5mm - 3000mmNickel coilThickness: 0.3mm - 16.0mmWidth: 1000mm - 3000mmNickel pipeOutside diameter: 6mm - 1219mmThickness: 0.5mm - 100mmNickel Capillary PipeOutside diameter: 0.5mm - 6.0mmThickness: 0.05mm - 2.0mmNickel barDiameter: Ф4mm - Ф600mmNickel wire rodDiameter:Ф0.01mm - Ф6mmDetectionProcessing 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 .
