Pressure vessel steel grades are special steel grades that are designed for the manufacture of containers that must withstand high pressure and temperature loads and must not show any cracks or other damage.

The CTOD test is an important test standard for steel. It simulates the formation of cracks and helps to determine the material’s crack resistance. Read here how the test works and what advantages it offers.

The first delivery of the wear-resistant Creusabro^® 6400 has arrived! Our wear expert Björn Fischer has personally inspected the delivery and is delighted!

Our trainees Paulina, Fritz and Moritz successfully took part in this year’s “EnergieScouts Niederrhein” project organized by the Lower Rhine Chamber of Industry and Commerce and secured the coveted 3rd place!

We continue to optimize our production processes: In Hall 1, where we store heavy plates from 30 mm thickness, we now use powerful crane magnets with a penetration depth of 90 mm.

The DWT test, also known as the Pellini or drop weight test, determines the Nil Ductility Transition Temperature (NDT) and is used to assess the fracture resistance of ferritic steels.

For use in pipelines and pressure vessels that come into contact with sour gas, steel grades with high purity, homogeneous microstructure and low sulphur content are essential in order to prevent hydrogen-induced cracking (HIC).

Steel is an indispensable material in many industries. Its high strength and rigidity make it ideal for the construction of bridges, machines and systems. But how can you calculate how resilient steel is? This is where the modulus of elasticity comes into play.

The volume of orders in the steel industry is subject to numerous external influences that often call for complete solutions from a single source. Thanks to forward-looking planning and flexible options, UnionStahl is also ideally prepared to meet special requirements. Learn more

We are adding another green steel to our range: ^alform® plate 700 M greentec steel Edition from voestalpine.

Our journeyman’s workshop for prospective construction and machining mechanics has been expanded: in addition to the workshop, the area now also has its own training room, with vinyl flooring laid by our trainees themselves.

Substances containing hydrogen sulphide can lead to corrosion and hydrogen-induced cracking (HIC) in steel containers.

Sustainable materials for pipelines are gaining ground.

The service life of machines and systems is crucial for the smooth running of industry.

When UnionStahl GmbH was founded in 2002, there was a vision: sheet metal should not only be sold, but intelligent solutions should be developed around the product in the interests of the customer.

We are expanding our range to include API 2W-50 sheets in thicknesses of up to 100 mm – for the highest demands in offshore projects.

Resistance to dynamic stress is of crucial importance. The DWTT test focuses on this property and provides important findings.

In a remarkable campaign, children from the Sankt Josef children’s home decorated our fir tree in the head office with paper stars on November 29.

This year’s fall conference was dominated by exciting specialist presentations.

Steel is and remains an indispensable raw material for a wide range of industries.

The steel industry is a core industry of the German economy and Germany is one of the largest steel producers in the world. Steel is used as a raw material and primary product in a wide range of industries. Union Stahl GmbH from Duisburg is an independent, medium-sized company in this sector that focuses clearly on its customers and employees.

The initial situation for CREUSABRO 4800: Large dimensions and long service life. UnionStahl has maintained a close business relationship with one of the world’s leading tunnel construction companies for over 15 years.

Due to its strength in the area of pre-processing, UnionStahl is often asked to provide support in the development of solutions for subsequent series production. In the current example, UnionStahl has been working for the market leader in the construction of cold milling machines for around twelve years. Initially, UnionStahl supplied flame-cut parts, but later also manufactured machined components in addition to laser parts …
