Alloy 660 is a precipitation hardening alloy, which maintains superior strength at high temperatures up to 700℃, surpassing austenitic stainless steels. With a higher nickel content, Alloy 660 also includes such elements as titanium and aluminum for hardening. Age hardening is used to precipitate γ' phase [Ni3 (Al, Ti)] making this an extraordinarily strong metal at high temperatures. Alloy 660 is an excellent choice when high-temperature strength is required such as jet engines, gas turbines and turbo charger components.Alloy 660 SpecificationsGradeUNSAlloy 660S66286Alloy 660 Chemical CompositionGrade%NiCrMoBPAlTiCMnSiVSFeAlloy 660Min2413.51.00.001 1.95 0.10 Bal.Max27161.50.010.040.352.350.082.01.00.500.03Alloy 660 Mechanical properties：(Minimum value at 20℃)ClassTensile Strengthσb/MPaYield Strength σp0.2/MPaElongation σ5 /%Class A,B,C≥895≥585≥15Class D≥895≥725≥15Alloy 660 StandardsBarASTM A453Alloy 660 Size RangeWire: Dia 0.08-12mmBar: Dia1.0-300mmStrip(Coil): 0.2-20mm TCK x 10-300mm WSheet: min.0.7mm TCK x 1200mm W max.Tube & Forging & Machine Parts: customizedWelding wire: 0.8mm,1.0mm,1.2mm,2.0mm,2.4mm,3.2mm,3.8mm,4.0mm etcWelding Strip: 0.4-0.7mm TCK x 25-60mm W
