An austenitic, substantially ferrite-free steel alloy and a process for producing components therefrom. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Corrosion-resistant austenitic steel alloy

Process for producing a corrosion-resistant austenitic alloy component

Component for use in oil field technology made of a material which comprises a corrosion-resistant austenitic steel alloy

A material which is suitable for equipment in oilfield technology and a process for making the material. The material consist essentially of C, Si, Mn, Cr, Mo, Ni, Cu, N in certain weight percentages, with the balance iron and contaminants due to manufacture. The material is hot formed in a condition free of nitride precipitates and without precipitated associated phases. After a cooling, it is cold formed in a condition free of ferrites. The material has certain values of relative magnetic permeability, yield strength (R ), notched impact strength, fatigue strength under reversed stresses, and fracture appearance transition temperature.
