Common spring steel

This article will introduce several common spring steels:

1. Carbon spring steel

This kind of spring steel has the advantages of low cost and convenient source of raw materials, but its disadvantage is that its elastic limit is low. It is easy to lose elasticity after repeated deformation for many times, and it cannot work normally in the temperature environment below 130 degrees.

2, low manganese spring steel

This spring steel (such as 65Mn), compared with carbon steel, has the advantage of higher hardenability and strength, but also has obvious shortcomings such as easy to crack and hot brittleness after quenching. But because the price is cheap, so often used in the general mechanical size of the spring manufacturing, such as clutch spring.

3, silicon manganese spring steel

This spring steel (such as 60Si2Mn), because it contains silicon, has a significant increase in the elastic limit and tempering stability, so it can be tempered at a higher temperature to obtain good mechanical properties. Silicon manganese spring steel is widely used in industrial manufacturing, such as coil springs of automobiles and tractors.

4, chromium vanadium steel

The purpose of adding vanadium to such steels, such as 50CrVA, is to refine the structure and improve the strength and toughness of the steel. This material has good fatigue and impact resistance, and can work stably at temperatures ranging from -40 degrees to 210 degrees, but is usually more expensive. Generally used in the use of higher requirements of the occasion, such as aero-engine regulating system spring production.

The above is the introduction of several common spring steel materials, I believe that through the above content, you have a further understanding and understanding of various spring steel used in different occasions, I hope the above content can be helpful to you!
