Elastic alloys are widely used in the machinery and instrumentation manufacturing industry to produce a variety of parts and components of the basic materials, it is in all types of machinery and instrumentation in the main role: through the deformation to absorb the vibration and impact energy, and moderate the vibration and impact of the machinery or parts; the use of their own deformation of the energy stored in the control of the movement of the machinery or parts; the realization of the media isolation, sealing, flexible shaft connections and other functions. You can also use the elasticity of elastic materials, corrosion resistance, magnetic conductivity, electrical conductivity and other physical properties, made of instruments, instrumentation components, pressure, tension, temperature and other physical quantities into displacement, in order to measure or control these physical quantities.
3J21 (1Cr20Ni16Mo7Co40) is a cobalt-based elastic alloy with excellent overall performance, high modulus of elasticity, high elasticity limit, and very low elasticity after-effects (0.02%). After cold working its tensile strength Rm up to 2950Mpa. also has a high fatigue life, high hardness, high wear resistance, low notch sensitivity, working temperature up to 400 ~ 500 ℃. Mainly used in the production of shafts, tension wire, special bearings, the elastic sensitivity of the high requirements of the elastic components.
This alloy has the following characteristics:
3J21 is an elastic alloy containing 40% cobalt, the three characteristics of the alloy: non-magnetic, corrosion-resistant, high elasticity?
3J21?s metallurgical structure:
