Amagnit 509 for efficient and controlled directional drilling

05th December 2017

The steels used in directional drilling for oil and gas must meet three important criteria: To withstand the mechanical loads caused by the movement of the drill string, the steel must display maximum strength.

Use in aggressive media also requires good corrosion resistance. To obtain unfalsified location results from the measuring instruments that are based on the earth’s magnetic field, it is also important that the drill string components must be non-magnetic particularly near the measuring equipment. Deutsche Edelstahlwerke now introduces the special steel Amagnit 509, a solution right for a variety of applications and comparably affordable.

 

Efficient directional drilling

Amagnit 509 is the ideal choice for the tools used in directional drilling. During directional drilling, even the smallest deviations from the correct angles can result in missing the intended oil deposit. During the drilling process, control measurements are taken regularly for this reason with the help of the earth’s magnetic field in order to determine drilling location and direction accurately. To prevent deviations in direction, the measuring unit and the drill line components nearby must be made of a non-magnetic material, meaning they must be magnetically permeable while having no magnetic properties of their own. This quality as well as high strength and outstanding corrosion resistance of Amagnit 509 are the prerequisite to the performance and reliability of the components. Users profit from a true competitive advantage.

 

Amagnit 509 is available as forged bar in a warm-cold-hardened condition from 75 to 250 mm (2.95 to 9.84 in) in diameter. On request bored bars with IDs between 2 and 3-1/2‘‘ are available as well. 

Deutsche Edelstahlwerke, a company of the SCHMOLZ + BICKENBACH Group, is expanding their product portfolio with non-magnetic stainless steels for the oil and gas industry. Amagnit 509 allows Deutsche Edelstahlwerke to offer customers an optimized cost-benefit ratio for applications requiring high resistance to pitting. The new development is much more affordable than Amagnit 601 given comparable high strength and ductility values. With a 28 to 33 PREN (Pitting Resistance Equivalent Number), the measure for corrosion resistance is comparable to the values of Amagnit 601 which range between 29.5 and 35 PREN. Deutsche Edelstahlwerke achieves cost savings by reducing the amount of expensive alloying elements in the optimized production process. To be able to continue to guarantee high strength, the steel specialist adds nitrogen to the steel melt.
