Ni-span Alloy

Ni-span AlloyPrecision Alloy 3J1/3J53Elastic Component Alloys (3J1 and 3J53) (YB/T5256-1993)*Ni-span alloy c-902, AMS 5225, UNS N09902, (Ni42CrTiAl),Chinese 3J53Note: A precipitation hardenable Nickel-Iron-Chromium alloy having an outstanding controllable thermoelastic coefficient characteristics and excellent strength and oxidation resistance in high temperature atmospheres. The alloy can be processed to have a constant modulus of elasticity at temperatures -45 C to 65 C. Applications include springs in precise applications, such as watches and weighing machines.GradeRelative GradeRussiaU.S.A.JapanGermanyU.K.3J136HXTO 7023J5342HXTO H41XTNi-Span C902 Elinvar ExtraSumispan-3 EL-3Ni-Span CNi-Span CGrade and Chemical Composition (see Table 1) Table 1 Grade and Chemical CompositionGradeChemical Composition (%)CMnsiPsNiCrTiA1Fe3J10.051.000.800.0200.02034.5~36.511.5~13.02.70~3.201.00~1.80Balance3J530.050.800.800.0200.02041.5~43.05.20~5.802.30~2.700.50~0.80BalanceNote: The size and shape must comply with the standard of GB/T15001for  elastic alloys .Mechanical Property (see Table 2 Table4) Table 2 Mechanical Property (for the delivery statue)GradeShapeDelivery StateThickness
