    摘要： An austenitic, paramagnetic and corrosion-resistant material, particularly in media with high chloride concentrations, the material having high strength, yield strength, and ductility, including carbon, silicon, chromium, manganese, nitrogen, and optionally, nickel, molybdenum, copper, boron, and carbide-forming elements. The material is preferably substantially completely austenitic. A process utilizing alloying technology that includes a deformation and synergistically results in production of a ferrite-free material that is reliably paramagnetic, is corrosion-resistant, and has high yield strength, strength, and ductility. The material can be very beneficially used, for example, in connection with oil field technology, such as for bore rods and drilling string components as well as for precision-forged components, and for high strength attachment and connection elements.

    摘要： 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 (Rp0.2), notched impact strength, fatigue strength under reversed stresses, and fracture appearance transition temperature.
