Spring steel

Spring steel is used in applications where the resilient properties are the primary function. It is well suited where the steel is subjected to very high loads and where the object should return to its original shape despite being subjected to bending and twisting. Spring steel has both high yield strength and tensile strength.

Spring steel - a high strength steel for strips, springs and tools

Spring steel is a term used for many different grades of steel. The properties of spring steel mean that it has several applications, mainly in the following areas

  • springs
  • tyre
  • sheet metal
  • round bars
  • flat bars
  • flat iron
  • different types of tools
  • saw blade
  • knives.

Spring steel is commonly used in the automotive industry, for example, and is also available in stainless steel.

Spring steel - properties and hardening

Due to the high carbon content of the spring steel, the steel has a very high strength. To get the most out of the properties of spring steel, the steel should be hardened. Depending on the steel grade chosen for the hardening process, the steel can reach a hardness of about 60 HRC.

It is important to note that the brittleness of the steel becomes higher after hardening. Therefore, any machining, such as bending, be made before hardening is carried out. Thin material can sometimes be bent in the hardened state, but some consideration must be given to the fact that the material may have some springback.

When fatigue loading occurs, the spring steel needs to have a high degree of cleanliness and a good surface finish.

Spring steel from Livallco

Livallco offers several different grades of spring steel. Here you will find high-carbon steel for springs with high yield strength and medium sensitivity, but also low-alloy steel for use in a quenched and tempered condition.The low-alloy steel is used for parts that require hardness and strength, such as shafts and piston rods. This makes the steel ideal for, for example, resilient components in the automotive industry.
