Common Types of Spring Steel
Spring steel is a special type of steel that is used for making springs and other components used in specialized applications. It has a higher resistance to fatigue and corrosion and is able to withstand greater forces than many other metal alloys.
Spring steel is usually classified as either hard-drawn, oil-tempered, or pre-tempered metal, each of which has its own properties and characteristics that define its function. Depending on the specific applications, one type of spring steel might be more suitable than the other.
Hard-drawn steel is often referred to as the workhorse of spring steel types due to its strength and ability to resist fatigue and corrosion over a long period of time. This type of steel is very strong and can withstand high compression loads without breaking. It also retains a good strength-to-weight ratio and can also retain its elasticity and resiliency over a long period of time.
Oil-tempered spring steel is created using a hot-working process where oil-tempered steel is heated at a hot-working temperature and then quenched in oil. Oil-tempered spring steel is extremely strong and retains a good toughness and resiliency in both high and low temperatures. The hot-working process also increases the safety level of the steel and makes it resistant to fatigue over a long period of time.
Pre-tempered spring steel, also known as chrome silicon steel, is created by heating the steel to a specific temperature and then quenching it in oil. It is a very strong type of steel with high fatigue properties and excellent tensile strength. This type of steel has good corrosion resistance, making it ideal for use in applications with varying temperature and stress ranges.
Whether you are looking for a spring steel type for use in industrial applications or for custom designs and prototypes, it is important to understand the basic properties of each type of steel so that you can choose the best option for your specific needs.
Hard-drawn steel is typically used in applications that require a high load-bearing capacity and features a high-yield strength and fatigue resistance. This type of steel is often used in applications such as aircraft, automotive and industrial equipment, pressure vessels and bridges, as well as in mechanical springs, as it has excellent shock absorption capabilities.
Oil-tempered spring steel is often used in applications where temperature fluctuations are common, such as medical instruments, small machinery, and industrial valves. This type of steel is very tough and resistant to fatigue and corrosion, making it perfect for applications where components must endure high stresses over long periods of time.
Pre-tempered spring steel is used in applications where extremely high strength and fatigue resistance are required. These types of springs are often used in motors and engine components as well as for suspension and shock absorbers, as they are highly resistant to corrosion and stressful environments.
Spring steel is an essential part of a wide range of products and applications due to its unique properties and ability to provide durability and strength. With the right type of spring steel, you can ensure the long-term function and performance of your components, regardless of the application.
