Techman are part of the Schoeller Bleckmann Oilfield Equipment Group, who provides and stock specialised non magnetic steel. The austenitic steels are developed through Schoeller Bleckmann Oilfield Technology specifically for use in the oilfield industry. They are characterised by particularly high material strength, non-magnetic behavior and stress corrosion resistance.

The non-magnetic steel has a particularly high degree of purity and undergoes special processess such as cold forging and surface finishing to give a high resistance to stress corrosion.

The standard material P530 is enhanced by P540, P550, P580 and P650. The stainless steel alloys, P550, P580, P650 and P670 have a higher chromium and nitrogen content, which provides greater resistance to pitting corrosion (pitting). At the same time, the material has better mechanical properties and improved fatigue resistance. Our material type P750 also represents a competitive alternative to conventional Nickel-Base alloys.

N850 is a new Nickel-Base material on the market which provides highest mechanical strength combined with a corrosion resistance beyond most of the standard Nickel-base alloys.

The P650, P670 and P750 materials are also available in high strength variants that have even higher mechanical properties.

Techman holds a stock of bar at various diameter's and lengths, material datasheets are available in the download section of this page.
