Business Opportunity Information

How much do you know about spring classification?

Today to introduce to you what are the common classification of spring

How to improve the service life of the compression spring?

Whether the compression spring is in use or in consumption, its service life must be considered. Usually during use, we will shorten the service life of the compression spring due to improper use. The following are ways to increase the service life of compression springs:

What are the problems of tempering treatment?

Avoid tempering the spring in such a way that increasing the temperature shortens the time.

Why do springs need tempering treatment?

To strengthen the tensile strength, one of the purposes of tempering treatment is to improve the resistance strength, to ensure the normal rebound, to ensure the effect of the spring. The spring after tempering can increase the tensile strength to more than 90%, reducing the creep resistance of the spring.

There are several common ways of tempering

Tempering is one of the commonly used spring steel heat treatment methods, usually by reducing the hardness of spring steel and improve its toughness, to make its performance more stable and suitable for different application environments. By controlling the parameters such as heating temperature, holding time and cooling rate of tempering, the spring steel can be restored to the degree of toughness and strength, and the state suitable for the application environment can be achieved.

What is the purpose of tempering the spring

After solution treatment and quenching, the hardness and brittleness of spring steel will be greatly increased, and tempering can reduce the hardness of steel and improve its toughness and ductility by controlling the heating temperature and holding time.
