Shuangyuan Disc Springs CO.,LTD

Material Selection Of Disc Springs

At present, our country disc springs of materials with high quality spring steel 60Si2MnA, 50CrVA or other special materials, such as stainless steel, Chrome-nickel-iron alloy, etc.

special material, stainless steel, Chrome-nickel-iron alloy suitable for high temperature and corrosive environment.

However, we find that a kind of material, at the same time satisfy the high strength, high temperature resistance, corrosion resistance, resistance to the magnetic field, is impossible, can only seek some performance maximization, such as high strength or high temperature resistant and corrosion.

So when the user place an order for disc spring, what the operating mode requirement be clear,our technical staff will fully consider the most negative factors, choose one kind of appropriate material, recommended for customer.

Below we list abroad comparatively typical disc spring materials for your reference:
