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.
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
quality assurance (QA)
quality assurance (QA) At our company, a team of in-house certified inspectors handles this process, utilizing a wide range of non-destructive and destructive testing methods, precise 3D measurement, and complete batch traceability. This ensures that every component meets our quality standards and complies with applicable regulations.

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).
