Spring steel is a kind of steel specially used for manufacturing springs. Its main feature is that it has good elasticity and willfulness, and can withstand large pressure deformation without breaking. So, what are the common spring steels and their uses?
What are the common spring steels and their uses?
Currently, there are many common spring steel materials on the market. According to the alloy elements added to spring steel, it can be divided into the following common types.
- Carbon spring steel, with a carbon content between 0.6% and 0.9%, has high elasticity and strength. The advantage of this type of steel is lower cost, but the disadvantages are also obvious, such as poor corrosion resistance and easy loss of elasticity after repeated deformation. Suitable for general requirements of compression springs, tension springs, torsion springs, etc.
- Low manganese spring steel. This kind of steel has a higher content of manganese elements, which improves its hardenability, allowing the steel to harden better after quenching. Compared with carbon spring steel, it has higher strength and can withstand greater working load, but it is prone to cracks after quenching. It is widely used in manufacturing various small-section flat springs, round springs, springs, etc. It is also suitable for manufacturing clutch springs, brake springs, etc.
- Silicon-manganese spring steel, the addition of silicon and manganese elements improves the elastic limit, strength and hardenability of the steel. Spring steel can achieve ideal mechanical properties, such as a balance of strength and toughness, through heat treatment. It is suitable for manufacturing springs that bear larger loads, such as flat springs or coil springs with wire diameters below a certain size in the automobile and tractor industries.
- Chromium vanadium steel. This type of steel contains a higher proportion of chromium, which increases the strength, hardness and corrosion resistance of the steel. Widely used in various tools and mechanical parts, such as cutting tools, bearings, gears, springs, molds, etc. At the same time, it also performs well in some special environments, such as petrochemical, marine engineering and other environments.
To sum up, each spring steel has its own performance characteristics and specific application scenarios. But no matter which spring steel we choose, we must strictly control its production process. When choosing, we should make a decision based on the specific working conditions and performance requirements of the spring.
