Elgiloy AlloyPrecision Alloy 3J21*Elgiloy alloy(Co40CrNiMo),AMS 5833,UNS R30003,Chinese 3J21Usage: It is applied to make antimagnetic, corrosionproof and long range elasticity alloy for elastic cell.Note: This Cobalt-Chromium-Nickel alloy also known as Elgiloy gives a combination of high strength, ductility and good mechanical properties and is age hardenable. Phynox also has excellent fatigue life, corrosion resistance in numerous environments and is non-magnetic. This alloy is recommended where a high resistance to corrosion and / or low relaxation at temperatures up to 380 C are required.Relative Grade:RussiaU.S.A.JapanFranceStandard40KJXMElgiloyNAS604PH K R NphynoxYB/T5253-1993Grade and Chemical Composition (see Table 1) Table 1 Grade and Chemical Composition of 3J21GradeChemical Composition(%)CMnSiPSNiCrCoMoFe3J210.07~0.121.70~2.300.600.0100.01014.0~21.019.0~21.039.0~41.06.50~7.50BalanceRemark: The size and shape must be tally with the standard of GB/T15006 for ?elastic alloy .Mechanical Property(see Table 2) Table 2 Mechanical PropertyShapeDelivery StateThickness&Diameter/mmProperty&ClassficationMechanical PropertyTensile Strength ( b/Mpa)Elongation ?(%)StripCold RollingTk0.20~2.50A1175~14705B1470~17653WireCold DrawnDia0.20~5.00A1275~1570B1570~1865The strip has been used typically for springs requiring a combination of high strength up to ? ? 800 F(427 C),excellent corrosion resistance, and good fatigue properties, but usage is not limited to such applications.
