Hellwig Products has been making vehicular helper springs and sway bars in the US since 1946. We heat treat our steel in the manufacturing of our sway bar and helper spring kits, but you may ask why this is important, and what heat-treating even is.
To provide some background, we start with what heat-treating steel entails. There are four types of heat treatments steel can undergo annealing, normalizing, hardening, and tempering. At Hellwig, we heat treat the steel through the hardening and tempering methods, which go through the following stages:
- Slowly heat the steel, uniformly
- Quench the steel in an oil bath after forming
- Temper the steel by putting it in a grieve
It is important to slowly cool the steel via the quenching to grieve method, in our case, as heat treatments can make the original material brittle, which can lead to warping or cracking. This helps the steel regain its composition and harden into its sturdier final state, without defects in the material or shape of the parts we form. The parts we manufacture are constantly under heavy stress, so it is important that they are strong enough to withstand that stress without failing due to defects in the manufacturing process.
By completing these stages of the heat-treating process, we lead into the benefits of why heat-treating is important. Heat treating increases the strength and life of the parts we manufacture. This helps to ensure the parts will withstand the rigors of use throughout the life of the vehicle on which they are originally mounted. If we did not use our heat-treating process, the springs and sway bars could potentially crack or fail, due to the amount of tension put on the components.
We find it beneficial to take these extra steps when forming our parts to ensure maximum durability so that we can continue to keep you safe on your journeys.
