KX Co40CrNiMo Elastic Properties Strong Support Light Rod On Elastic Alloy
Product Description and Application
Co40CrNiMo is also known as 40KHNM (Russian), Elgiloy alloy, elastic alloy 3J21,AMS 5833,UNS R30003, NS604PH,K.R.N
Co40CrNiMo has good plasticity and easy to work in solid solution state. After cold working and aging treatment with large strain rate, high mechanical and elastic properties are obtained. It has high hardness, strength, elastic limit, energy storage ratio, fatigue strength, elastic lag and after-effect, non-magnetic, good wear resistance, shock resistance, excellent corrosion resistance and working temperature can be up to 400 ℃, which can also work at low temperature.
