Is the use of elastic material production gasket, it has a certain elasticity, when the force, will be conducive to the tension of the material to the two sides of the diffusion, so as to achieve the effect of anti-loose.

Requirements

It can not be used alone, can only be used in nut and bolt matching process.

The reason why spring washer material must be spring steel or just stainless steel is mainly due to the advantages of spring washer material and its application field, such as spring steel spring washer properties are slightly higher elasticity and strength.

Suitable for manufacturing cross-section, and stainless steel spring cushion strength requirements are not high, general machine round, square spiral spring washers, such as cars, flat spring, circular spiral spring washers in the mechanical vibration of tractors or trains in the anti-loose effect is better.

Spring steel gasket material refers to manganese steel. Manganese spring steels are commonly used, and steel structures are made of steels with high manganese content.

In terms of strength, the manganese spring cushion performs better, while stainless steel does not rust. This is its advantage.

If you say who is good, it depends on what kind of functionality is needed in the actual application.

Spring washer is one of the simplest and most common fasteners. Although the screw is small, the safety is big. The more insignificant the product is, the more likely it is to be ignored.

Spring washers are widely used, low cost, whether stainless steel spring washers or galvanized spring washers, its cost is basically a few cents, of course, larger specifications will be more expensive.

After years of development, many countries have abandoned the use of spring washers, this is why?

Because the spring washer is easy to hydrogen brittle fracture, the material itself does not meet the requirements will break, improper surface treatment will break, the production is not standard will also break.

In short, although the product is simple, but a lot of problems do not pay attention to. So now stainless steel spring washer is used more and more, because there will be no hydrogen brittle fracture.
