Hellwig Sway Bars are design to reduce body roll on your vehicle which will result in better control and improved cornering traction for safer driving and cornering capabilities. Each sway bar is made from high quality 4140 chrome molly steel and powder coated to give you a durable addition to your suspension. But have you ever wondered what gives your sway bar it’s toughness?
Every Hellwig Sway Bar is heat treated, a process used to change the crystalline structure of the steel to improve its strength, toughness, and hardness. The heat treating process can double the tensile strength of alloy steel while still maintaining its toughness and ductility. Not all aftermarket sway bars are heat treated. They may be made from alloy steel, but unless it has been heat treated, the alloy steel is not being processed to its full potential. This is what sets Hellwig Sway Bars apart from the competition.
The process used at Hellwig is a multi-step process that provides a tough, durable product that will last a lifetime. The 4140 chrome molly steel is received as hot rolled material from the steel mill. As is, it has a tensile strength of 95,000 psi. After the heating process, Hellwig Sway Bars have an average tensile strength of 180,000 psi.
The first step in the heat treating process is called “coining”.
In this process the ends of the sway bar are formed maintaining the integrity of the sway bar. Hellwig sway bars are never welded as the heat affected zone of the weld will compromise the material.
Once the ends are coined, the sway bars are heated to 1,600 degrees Fahrenheit and formed to the desired shape.
Every Hellwig sway bar is developed for a specific vehicle application.
Once the bar is form to shape, the bar is cooled in a quenching tank to reduce the temperature from 1,600 degrees to 150 degrees Fahrenheit.
Hellwig uses a specially formulated quench oil to improve the crystalline structure of the steel, increasing its tensile strength.
The next step is tempering of the metal. The sway bars are moved to a tempering furnace where they are heated to 1,000 degrees Fahrenheit. This process improves the toughness and ductility of the sway bars while maintaining a high tensile strength.
Once the bars are removed from the furnace, they are checked for correct dimensions and then powder coated in a hammertone finish.
