Degerfors Quarto Plate

Business Area Europe

Outokumpu’s largest plate mill, Degerfors would be noteworthy for its output alone. But Degerfors is also famed as a leading global manufacturer of tailor-made stainless steel quarto plates.

The Degerfors mill specializes in stainless steel heavy plates – quarto plates – in nearly infinite forms. Boasting a uniquely comprehensive program of wide dimensional and alloy products, Degerfors offers more than 60 grades and 300 custom-made variations.

Using highly advanced, state-of-the-art technology, Degerfors manufactures the world’s largest share of products in Pro family austenitic and duplex stainless steels. Demonstrating exceptional versatility, the mill produces quarto plates in dimensions up to 110 mm in thickness, 3,200 mm in width and 13,500 mm in length.

In addition to standard grades and dimensions, Degerfors offers prefabricated plates that are cut or cut-to-shape to specified size with edges prepared for subsequent welding. Press break and roll-forming are among the prefabrication services available at Degerfors.

The Degerfors site also includes a production unit for Long Products, Outokumpu Stainless AB – Degerfors Stainless (part of Long Products BA), and a nearby Plate Service Center, PSC Nordic, specializing in plasma cutting, water jet cutting and bending of plates.

Degerfors has a proud history in metal production dating to the 17th century, when the city’s first ironworks was founded. In 2014, Outokumpu set the stage for a new era in steelmaking through completion of a major investment in the Degerfors mill.
