Soft annealing
We reduce the hardness of your steel to an absolute minimum. By forming cementite, we significantly improve cold formability and machinability, even for extremely high-strength steels.
Maximum deformability without risk of cracking
In soft annealing, time is a critical quality factor. Through our high-precision, extended-duration cycles, we ensure that the cementite fully forms. The result is an extremely soft, crack-resistant material that you can then machine safely and efficiently.
Soft annealing
Annealing followed by slow cooling to achieve a condition that is sufficiently soft and as stress-free as possible for the intended application, primarily to ensure good machinability.
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 comprehensive batch traceability. This ensures that every component meets our quality standards and complies with applicable regulations.
For a comprehensive and audit-ready Documentation Handled by our own team. All materials, components, and filler metals remain traceable; all documentation is stored in an audit-proof manner and prepared in accordance with standards and individual customer requirements.

Questions about soft annealing
How long does a complete soft annealing cycle take? For which tool steels is this process essential prior to machining? In this section, we explain the details for maximizing machinability.
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).
