Cleaning before and after heat treatment

Avoid residues, hardening defects & complaints - with process-safe cleaning before and after heat treatment.

Why cleaning is crucial

In order to ensure the required surface quality in hardening processes such as gas nitriding, upstream cleaning is a crucial step in addition to the actual heat treatment. Non-visible (diffusion-inhibiting) layers lead to defects that only become apparent after the thermal process.

Prevent diffusion problems, oil carryover and reworking - with our high-performance 1-component products or modular cleaning systems.
