Thermal or thermochemical processes are used to specifically change the properties of materials and optimize them for the specific application. For example, wear resistance, machinability, corrosion resistance, formability, hardness, magnetic and electrical properties are improved through appropriate Heat treatment. Depending on the requirements, only the surface or the entire component volume is processed.
Listemann has many years of experience in materials engineering and heat treatment technology at its disposal. Countless applications in the most diverse areas have been successfully tested and implemented over the years.
We not only focus on steel, but also specialize in many other materials, such as nickel-based materials, titanium, aluminium and copper. This also includes all alloys of these materials through to special metals such as molybdenum, tantalum, magnesium and many more.
Thanks to the diversity of our heat treatment furnaces, we are able to thermally process micro parts for hearing aids or watches as well as fuel tanks for satellites or large gears for ship propulsion systems.
Our systems are not only calibrated in accordance with AMS2750 (aviation standard), but also benefit from regular cleaning procedures, which mean that we remove bright metallic parts from the vacuum furnace. This saves you time-consuming and cost-intensive finishing processes such as electropolishing or pickling. This is particularly important for medical instruments.
We have held a NADCAP Certificate for various heat treatment processes since 2004 and have been continuously expanding our experience in the certified business field of Aviation & Aerospace ever since. We transfer and use this experience for high-quality applications in medical technology, among other things.
Listemann hardens your components in a vacuum with high-pressure gas quenching - ideal for precision parts, tools and martensitic stainless steels.
Listemann achieves increased toughness and dimensional stability through controlled heating of hardened components.
With its solution annealing processes, Listemann makes a decisive contribution to ensuring that your components remain reliable, durable and efficient.
During the hardening of metals, a finely dispersed precipitation structure is created through targeted Heat treatment.
Precise Heat treatment for low-distortion components: With stress-relief annealing, we reduce residual stresses in a controlled manner - reproducibly and in line with the material.
Soft annealing of steel, stainless steel, aluminium & copper: targeted reduction in hardness, improved machinability, homogenization of microstructure.
Listemann ensures an even distribution of alloy components in the component.
Heat treatment in a vacuum/inert gas for soft magnetic peak values: higher permeability, lower losses, reproducible quality.
Gentle curing of diffusible hydrogen after coating, pickling, welding or forming. Process-safe, standard-compliant, documented - from Listemann.
