Our Service Concept

Be it in-depth consulting, efficient logistics or comprehensive quality control - HT Plus enables you to benefit from numerous offers that make your daily work easier or help further enhance your product quality.

Competent consulting is simply part of the job

Our specialists have decades of know-how and wide-ranging experience, putting them in a position to inform and advise you on every aspect of the subject of hardening steel, as well as on applications, processing options and availability.

Flexible deadlines

Having the structure of a medium-sized enterprise, our organisation is such that we can usually fill even an unscheduled order quickly. So that you can deliver punctually every time.

Faster by e-mail

As soon as your workpiece is finished, you immediately and automatically receive personal notification by e-mail. In this way, you can either quickly pick up the workpiece again in person, or use our collection and delivery service.

Collection and delivery service

No time? No problem! If your appointments calendar is full, or you have no transport capacities available, feel free to use our unbureaucratic collection and delivery service. We arrange an appointment to collect your workpieces and deliver them back to you promptly as soon as they are finished.

Test service

Our laboratory is equipped for metallographic examinations, surface tests and spectral analyses. As a result, we can perform non-destructive quality testing on both the starting material and the heat-treated workpieces.

Practical seminars

As your professional partner for heat treatment, we organise practical seminars that give an insight into the heat treatment of tools and machine components.
