Core Competencies

Heavy Forming. Special Alloys. Documentation depth.

/ 01

Heavy Forming

Eight hydraulic presses from 150 to 1,500 tonnes. Hot and cold forming, hydroforming. Hot forming up to 1,150 °C in proprietary furnaces. Components up to DN 600, wall thickness up to 100 mm, part weight up to 1,000 kg.

/ 02

Special alloys as standard

Stainless steel, duplex and super duplex, nickel-based alloys (Inconel, Hastelloy), heat-resistant and low-alloy steels. Maraging steels and Cu-Ni alloys on request. Material diversity is our daily business, not the exception.

/ 03

Nuclear-grade documentation

ISO 19443 is the strictest civilian quality regime. Full traceability from heat to finished part. Material certificates per EN 10204 3.1 / 3.2. Defense audits are routine for us.

Hot Forming

Hot formed. Precisely documented.

Hot forming up to 1,150 °C in proprietary furnaces. Subsequent controlled heat treatment — solution annealing, tempering, stress relief — with documented process parameters. From hot billet to measured, tested and stamped finished part. All under one roof. All traceable.

Differentiators

Why Ruhr Defense

/ Capacity

Press park up to 1,500 t under one roof

Eight hydraulic presses plus hydroforming line — this combination is rare in Germany and Europe. Scalable batch sizes from one prototype to small series.

/ Integration

From billet to finished part

Forming, heat treatment, machining, pickling and blasting — all under one roof. No jumping between suppliers, no loss of control and documentation.

/ Quality

Nuclear-grade as defense advantage

We bring the ISO 19443 quality regime from nuclear supply chains. Defense requirements for traceability, process control and counterfeit prevention are met from day one.

Machining

Final geometry. Dimensional. In-house.

Turning, milling, sawing for final geometry and weld preparation. Tolerances per customer specification. Geometric inspection and dimensional control in-house. Sandblasting and pickling for surface-critical stainless steel applications. The finishing stays under our control — including all inspection and documentation steps.
