Spring steel

Spring steels are used for applications where the resilient properties are the primary function. It is well suited where the steel is subjected to very high loads and where it is desired that the object should return to its original shape despite bending and twisting.

Spring steel – a strong steel for springs & tools

Spring steel is mainly used as springs, tools, saw blades, knives, etc. and has a high strength due to its high carbon content. To get the most out of the properties of spring steel, the steel should be hardened. Depending on the choice of steel grade, the steel can reach a hardness of about 60 HRC. It is important to bear in mind that the brittleness of the steel will be higher after hardening, therefore any machining such as bending should be done before hardening is carried out. Thin material can possibly be bent in the hardened state, but some springback must be taken into account.

High-strength spring steel for e.g. the automotive industry

We offer both high carbon steels for medium strength springs and low alloy steels used in a case hardened condition. The low-alloy steel is used for parts that require hardness and strength, such as axles and piston rods. Over 30 years of experience in steel makes Livallco a reliable choice of supplier. Please contact us for more information and we will help you choose the right spring steel and finish for you.
