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).
