What You Should Know When Choosing Materials For Springs

Springs are made from various materials and finishes. There are some factors that decide which material is best. These include the application, requirements of the project, and the environment. In addition, the quality of the spring can have an impact on the performance. Here are some tips you should know about choosing materials for springs.

Common Material Choices

Most springs are metal from some type of steel alloy. This helps them remain affordable, durable, and readily available. In addition, the smallest changes to the steel can make the spring ideal for one application over another. Music wire, chrome silicon, oil-tempered wire, and stainless steel are the most common types. Today, approximately 40% of steel production around the world is made with recycled metal.

Stainless Steel

There are two types of stainless steel: 301 stainless steel and 302 stainless steel. 301 stainless steel resists corrosion in many environments. 302 stainless steel is used in most stock commercial springs. 302 stainless steel has a higher corrosion resistance than 301 stainless. It can stand up to incredibly high temperatures. 302 stainless steel is ideal for medical environments.

High Carbon Steel

An oil-tempered wire is excellent for heavy lifting. This type of spring is used on machinery and farm equipment. These springs have a larger diameter and therefore can handle much heavier workloads.

Music Wire

Music wire is a highly durable material that is ideal for the automotive industry and construction. These springs can handle the heavy loads and still maintain their form and build.

Hard-drawn Wire

This is the most affordable steel wire you can buy. It is versatile, easy to use, and sturdy. It is best used for temperatures that stay under 250 degrees Fahrenheit. It can perform in just about every other condition. Unfortunately, it does not have a long life and, as a result not best for the medical industry.

When deciding which type of steel spring to use, it is critical that you understand how you want to use the spring. This will help you make the best selection and pick a spring that is going to hold up to the task. In addition, no matter which spring you select, you want to ensure that it has been tested for durability and strength to handle all types of strain and stress.
