What Is The Material Of The Compression Spring?

    Compression springs are all helical springs, so what is the difference between the design of extension springs and compression springs? In fact, the difference between them is whether the two ends are rings or hooks. For example, if the two ends are rings, it is a compression spring, and if it is a hook, it is a tension spring. This is the difference. The shape of the compression spring is also divided into cylindrical and conical. Shaped, convex, special-shaped compression springs, etc. And its raw materials are too numerous to enumerate.

    (1) Ferritic steel: due to the addition of Ti element, its high temperature corrosion resistance and high temperature strength are better.

    (2) Silicon bronze wire: It has high corrosion resistance and antimagnetic properties. It is used for elastic elements for machinery and instruments.

    (3) Silicon manganese spring steel wire: high strength, good elasticity, and easy decarburization. Larger springs for general machinery.

    (4) Tin bronze wire: It has high wear resistance, corrosion resistance and anti-magnetic properties. It is used for elastic elements for machinery and instruments.

    (5) Stainless steel wire for spring: corrosion-resistant, high- and low-temperature resistant, used for small springs under corrosion or high and low-temperature working conditions.

    (6) Chromium vanadium spring steel wire: stable strength and performance at high temperature, used for springs at higher temperatures, such as internal combustion engine valve springs.

    (7) Carbon spring steel wire: used for high strength and good performance. Grades B, C and D are used for low, medium, and high-stress springs, respectively.

    (8) Oil quenched and tempered carbon spring steel wire: high strength and good performance. Suitable for general mechanical springs. Class B is stronger than class A.

    (9) Oil quenched and tempered carbon spring steel wire for valve: high strength and good performance. For internal combustion engine valve springs or similar springs.

    (10) Music wire: high strength and good toughness. For important small springs, G2 group has higher strength than G1 group, and F group is mainly used for valve springs.
