Success Story

The steel mill Augustfehn was founded in 1872 as a crucible steel works Schultze, Fimmen & Co. and converted in 1889 into the steel mill Augustfehn AG. Since that time, and through a varied history full of ups and downs, we have been supplying our customers with first-class forged quality products – because here, always, modern equipment and production processes are combined with traditional, solid manual work. This creates good relationships with customers and suppliers and thus productive market partnerships. Forged parts successfully assert themselves in technology competition.

Their outstanding properties in terms of strength, reliability and flexibility are well known to our customers in mechanical and plant engineering as well as in the recycling and dredging industries. These outstanding material properties of forgings are the trump card that must be put into the development process. And that puts you in the right place – at the Augustfehn steelworks, which has been dedicated to blacksmithing for more than 150 years and is always ready to face new challenges. Try it!

Introduction of a new ERP system.

Completion of the newly expanded administration building.

On to new challenges!

2012 Our new weighing station with own building will be completed and put into operation, a new ERP-System for order processing and a new financial system to go into operation, and the administration building is being modernized.

… and extension

The new hammer-hall and our exhibition space are put into operation.

Modernization …

The 1,000-ton oil-hydraulic underground-press is being modernized with new CNC control system and hydraulics.

Success Propelled by Innovation

We entered the new century and new millennium with a major expansion and modernization. The first “Ammerjazz Concert” on May 09, 2008 marked the inauguration of our new heat treating facility, expanded by 200% (2nd Section) (1st Section was completed in 2001). Also the quenching technique was changed from oil to polymer, and a new CNC (computer numerically controlled) flame cutting system with double water tables was purchased.

Success Propelled by Innovation

New annealing furnaces and a new CNC lathe for parts up to 6 m long were purchased. The control system for the presses was renewed and production capacity was expanded.

Success Propelled by Innovation

An additional forging furnace was purchased for 3-shift operation in conjunction with the 1,000 metric ton forging press.

Success Propelled by Innovation

The machining business is spun off into a new affiliated company, TurboMech GmbH & Co. KG.

Success Propelled by Innovation

Purchase of a new hardening furnace. It has the same basic design but has extensive heat recovery.

Success Propelled by Innovation

A new heat treatment facility (1st Section) is constructed and put in service. This accommodates the larger pieces produced by larger capacity presses. It includes an annealing and tempering furnace, followed by two quenching tanks.


The old GmbH is reorganized as “Stahlwerk Augustfehn Schmiede GmbH & Co. KG”, a limited partnership, in which “Stahlwerk Augustfehn Beteiligungs GmbH” is the general partner and the new “Stahlwerk Augustfehn GmbH” is the limited partner. The Benefits Association is liquidated, current claims for indemnity are converted, and all retiree pensions are re-funded separately.

Jubilee Year, Marking the 125th anniversary of the company

For the 125th year Jubilee, a new sawing facility was dedicated with an exhibit provided by local artists. Speeches were given by: Dr. Alfred Tacke, the Undersecretary of the Ministry of Economics of the German State of Lower Saxony; Dieter Schlecht, President of the Chamber of Commerce and Industry of Oldenburg; and Dr. Dieter Schwirten, Chairman of the Board of the Lignite Miner Lausitzer Braunkohlen AG. The steam forge, which was something of a historic relic, had been overhauled with the help of former workers and students, and was ceremoniously charged with steam for the last time (before being converted to compressed air operation).

Entering the Final Years 20th Century

Construction of a new sawing facility. The first 3D-CAD system in North Germany (supplied by Unigraphics) greatly increases our design and fabrication capability, particularly in the manufacture of parts for excavator buckets and other finished parts. The heat treating facility receives another annealing furnace with a recirculating furnace atmosphere, which aids in maintaining accurate temperatures even in the lower temperature range (1995). 1993: An additional forging chamber furnace is added. The 120 year Jubilee of the firm is celebrated (1992) with the start-up of a new press apparatus.


In the context of a management buyout, Peter Finkernagel and his family purchases all of the relevant segments from the famous industrial company Krupp Industrietechnik. The supervisory board is dismissed, and a basic overhaul of the equipment has begun. The vintage water hydraulic press of 1914 is replaced by a 650 metric ton hydraulic press with a controllable plunger. The conventional machines in the tool shop are converted to CNC (1989-1990). The hammer forges are modernized (1989). The old bushing forge (1990-1991) is converted to a bolt forge, and is replaced by a new “free form” open-die forge with a 10 MN force under-floor press having a base extending down 9 meters into the ground water.


The company has its best year (1976) for revenues, DM 17.3 million (8.8 Mio. Euro). Earnings of DM 811,000 are passed on to the parent company, along with an annual group contribution of DM 300,000. 1987: Dipl.-Ing. Peter Finkernagel becomes the sole Managing Director.

In the Sign of the Rings

Krupp-Industrietechnik also takes over Stahlwerk Augustfehn AG with Maschinenfabrik Buckau-Grevenbroich, converts the AG back into a limited liability company and concludes a domination agreement. Significant investments will be avoided in the following years.

Fresh Impulses

Dipl.-Ing. Werner Haring, former foreman at Deutsche Edelstahlwerke Krefeld, will be the new technical director.


Technical expansion phase of steam hammer forging with a new 50 metric ton hammer, and a freely movable Glama manipulator with a carrying capacity of 1.5 metric tons.


1948: The company is made essentially a subsidiary of another metals fabricator, Buckau-Grevenbroich (of Buckau near Grevenbroich), which is part of the Neuss-based Wehrhahn group. An extensive program of investment is undertaken, to rebuild and technically modernize the facilities. New construction includes a new workshop, a bolt forge, a bucket manufacturing shop (for excavator buckets and the like), and a hammer forge. Beginning in 1948, marketing is almost exclusively through Wegusta GmbH, of Düsseldorf.

Stahlwerk Augustfehn AG

The company is re-converted to a share corporation (AG), and becomes a subsidiary of Buckau-Wolf AG of Magdeburg.

Stahlwerk Augustfehn AG

On Sep 07, 1903, the company is registered as a KG (limited partnership) in the Commercial Registry of Oldenburg. Substantial investments are made until the start of World War I.

Stahlwerk Augustfehn AG

Production is focused principally on wear parts for cement mills and excavating machines (bolts, bushings, and excavator buckets).

Stahlwerk Augustfehn AG

A Supervisory Board is named on Dec 20, 1884. Substantial investments are made. The workforce increases to around 80 individuals.

Schultze, Fimmen & Co.

August Schultze and Johannes Fimmen found a steel mill on Augustfehn Canal.
