Abstract: Turbomachines, as well as their components, are disclosed being in the field of production and treatment of oil and gas containing e.g. hydrocarbon plus hydrogen sulfide, carbon dioxide, with or without other contaminants. The components are made of a high corrosion high temperature resistant alloy, capable of resisting to corrosion and/or stress at high temperature better than state of art martensitic stainless steels and behaving similarly to premium nickel base superalloys, and at the same time showing a very improved hardness value.

Abstract: Apparatus and method for decreasing the corrosion susceptibility and/or the liquid droplet erosion susceptibility of one or more turbine blades associated with a steam turbine. One or more of the turbine blades are constructed of an Austenitic Nitrogen strengthened stainless steel; such Austenitic stainless steel has a weight percentage of manganese bigger than ten and preferably a weight percentage of nickel smaller than five; advantageously, such Austenitic stainless steel is strengthened with nitrogen. The blades constructed of such Austenitic stainless steel are configured in the later stages of the steam turbine.
