ATI Datalloy 2® ESR alloy is a Cr-Mn-N non-magnetic Electro Slag Remelted (ESR) stainless steel. It has been specially developed to exhibit enhanced resistance to both pitting and galvanic corrosion. It is suitable for use in critical non-magnetic drill string components including MWD tools, LWD tools, Stabilisers and Compressive Service Drill Pipe.

Datalloy 2 ESR alloy has been designed to be used in place of standard Cr-Mn steels, in situations where increased corrosion resistance and ‘high strength' characteristics are required. Also the chemistry of Datalloy 2TM ESR ensures that galvanic corrosion caused by coupling to dissimilar metals is resisted.

The increased nickel content of Datalloy 2 ESR alloy does not adversely affect its resistance to Stress Corrosion Cracking or its galling performance.

Datalloy 2 ESR alloy complies, as a minimum, to the mechanical property requirements of API 7-1.

The material is also available in a "High Strength" condition with a guaranteed minimum of 140 ksi 0.2% yield strength.
