heat treatment

solution annealing

Essential for high-alloy and austenitic stainless steels after welding or forming. We restore the homogeneous microstructure, thereby guaranteeing maximum corrosion resistance for your systems.

Durable right down to the structure

Homogeneous structure, uncompromising corrosion protection

We safely return precipitated alloying elements to solution and “freeze” this state through rapid, controlled quenching. The result is a flawless, purely austenitic microstructure that provides lasting resistance to aggressive chemical media.

solution annealing

Annealing of austenitic steels, aluminum alloys, and other non-ferrous metals to dissolve the constituents precipitated in solid solutions and achieve a metastable state, followed by sufficiently rapid cooling.

Heat Treatment & Temperatures

  • Operating temperatures up to 1050 °C (up to 1070 °C for short periods)
  • Unrestricted operation throughout the entire lower temperature range

Frequently Asked Questions About Solution Annealing

Why is solution annealing often safety-critical for stainless steels? How quickly must quenching be performed, specifically? In our FAQ, we clarify the technical details for high-alloy materials.

What information do you need to prepare a specific quote? +

Component dimensions (max. length, width, height), component weight, desired heat treatment type (stress relieving heat treatment, normalizing, or other processes), desired surface treatment or cooling strategy, required process documentation, and, if applicable, standards (e.g., DIN/EN standards).

What specific characteristics or factors of your facility affect the quality of the heat treatment? +

Very high operating temperatures and controlled cooling rates support the required mechanical properties and stress relief. Large cooling tanks (polymer quenching tanks) and a variety of cooling methods allow for customized process adjustments depending on the material and component.

What advantages does your system offer specifically for heavy-duty welded structures? +

Performing stress relieving heat treatment or normalizing, as well as other specialized heat treatment processes. The large dimensions of the working area and high weight capacity enable the treatment of large and heavy components.

What types of bridge or process solutions do you offer in addition to heat treatment? +

Professional stress relieving heat treatment or normalizing, as well as other specialized heat treatment processes for optimizing heavy-duty welded structures. Goal: To relieve stresses and ensure the longevity of the components.
