Founded in the previous century – back in 1889 Hermann Böllinghaus and Johann Ludwig Härtel set up a company producing tool steels – Germany´s Remscheider Walz‐ und Hammerwerke Böllinghaus GmbH & Co. KG

Remscheider WalzRemscheider Walz‐‐ und Hammerwerke und Hammerwerke Böllinghaus GmbH & Co. KGBöllinghaus GmbH & Co. KG

After the end of World War II, the company´s rolling mill facilities were reconstructed, the forge closed down and production concentrated on file steel, tool steel and drill steel.

Production of stainless steel began at the early of the 1990s

A recent major development was the purchase of rolling facilities in Portugal in 1996 and the founding ofBöllinghaus Portugal Aços Especiais Lda. in Vieira de Leiria – Portugal's 1st stainless steel producer.
