Are you still designing steel components to accommodate the shortcomings of conventional or remelted steels? With conventional steel, you may get your costs down but strength and fatigue properties will be lacking. Remelted steels are a safer bet, but they are costly. What do you do?
Fortunately, there is a smarter way: IQ-Steel®. Developed specifically to meet the stress demands of high-performing mechanical parts, this isotropic-quality steel is ideal for gears, camshafts and other steel parts. Thanks to a unique manufacturing process,
IQ-Steel has few large inclusions or other impurities, meaning it can handle high mechanical forces in all directions.

The IQ-Steel process can be applied to a wide variety of steels. It is well proven in service in many applications, giving precisely the solution our customers demand, along with new beneficial properties. For example, IQ-Steel can be combined with a type of steel that gives very little oxidation depth compared to conventional steels, resulting in corresponding improvements to surface properties. This could potentially eliminate surface enhancement processes such as shot peening.
Our IQ-Steel offers equal strength in all directions, enabling optimized powertrain performance.
Equal performance in all directions
Increasingly, we hear from customers in the marine, transmission, engine, light and heavy vehicle and wind power sectors, that standard engineering steels are no longer suitable for tougher jobs. The pressure is on to create lighter, stronger and more compact designs. The problem with conventional steels is that they’re produced in a process where inclusions will be present in the steel’s rolling direction. As a result, they have poor fatigue and impact properties in the transverse rolling direction.
The beauty of IQ-Steel is that you get equal performance in all directions. When designing a gear, for example, you don’t need an extra-healthy safety margin, thicker walls or spacing to guard against failure. As one customer commented:“In hybrid drives, more things need to share the same space under the hood, so you need cost-efficient steel that enables compact, light and strong design.”
