High-Strength Non-Magnetic Steel

Schoeller-Bleckmann has developed and manufactured premium steels for more than 130 years. Around 50 years ago SBO started to focus on further developing, processing and producing high-strength non-magnetic steel grades for the oilfield industry. Precociously Schoeller-Bleckmann recognised that the non-magnetic steel grades can perfectly be used for Directional Drilling.

With its group-wide, long-term experience and state-of-the-art technologies SBO has become a perfect partner to meet the highly complex requirements of an industry that has turned into a high-tech market. Schoeller Bleckmann's non-magnetic steel excels by particularly high material strength and corrosion resistance. Special procedures such as cold-forging or finishing treatment make it highly resistant to stress corrosion. Continuous upgrading of high-grade steel alloys and machining technologies give SBO's customers the leading edge.
