As a common mechanical component, springs are widely used in various fields. In order to ensure that the spring can perform long-lasting and reliably, the steel used to make the spring must have high strength, toughness and wear resistance. There are four types of spring steel that meet the needs: carbon spring steel, low manganese spring steel, silicon-manganese spring steel, and chromium vanadium steel. These spring steels usually have the characteristics of high strength, toughness, and wear resistance, and are widely used in machinery and electronics. , aviation and other fields. In this article, we will introduce in detail the properties and applications of several common spring steels.
Common Spring Steels and Their Applications
- Carbon spring steel is a kind of steel specially used for manufacturing springs and other elastic components. Its main characteristics are high elasticity and strength. This kind of spring steel is the material of choice in many industrial applications due to its cost-effectiveness and processing performance. Its advantage is that it is cheap and easy to obtain. Common models include 65 steel, 70 steel, 85 steel, etc. However, this kind of spring steel is not easy to be quenched and is mainly suitable for small springs. It is widely used in the manufacture of small-section flat springs, round springs, etc.
- Low manganese spring steel contains 0.5%-1.0% manganese in its chemical composition. Compared with carbon spring steel, this steel has good strength, toughness and wear resistance. However, there are also some shortcomings, such as cracks and thermal brittleness that are prone to occur after quenching. The common model is 65Mn steel. Due to its good wear resistance, low manganese spring steel is often used to manufacture spring chucks, clutch springs, etc.
- Silicon-manganese spring steel. This kind of steel has high strength, good elasticity, long fatigue life, and can maintain high strength at high temperatures. It is usually widely used in the manufacturing of springs for automobiles, tractors, etc. The common model is 60Si2Mn steel. Because its strength, elasticity and hardenability are slightly higher than 55Si2Mn, it is industrially suitable for making flat springs that can bear larger loads or coil springs with wire diameters below 30mm.
- Chromium vanadium steel. This kind of steel contains two alloy elements, chromium and vanadium. After heat treatment, the hardness can reach more than 60HRC. It shows good wear resistance under specific working conditions. The common model is 50CrVA steel. Chromium vanadium steel is widely used in the manufacturing of automotive parts, wrenches, sockets, screwdrivers and other tools due to its high strength, high fatigue limit, high wear resistance, and high damping properties.
To sum up, each common spring steel has different characteristics and application areas. During the processing, it is necessary to select the appropriate processing technology according to its characteristics to ensure that the product has good performance and durability.
