The USS C100 steel grade, a proprietary product of U.S. Steel, is specifically tailored for deep sour service wells where the controlled yield strength is crucial. This article examines the mechanical properties of USS C100 steel, its suitability for sour service applications, and the standards it complies with, including API 5CT and NACE TM0177.
Deep sour service wells are characterized by high pressures and the presence of hydrogen sulfide (H2S), which necessitates the use of steel materials with enhanced resistance to sulfide stress cracking (SSC). USS C100 steel is designed to meet these challenges, offering a balance of strength, ductility, and SSC resistance.
USS C100 steel is defined by its mechanical properties:
USS C100 steel is generally used in deep sour service wells due to its controlled yield strength and compliance with SSC standards, making it resistant to the detrimental effects of H2S.
The steel meets the following industry standards:
USS C100 steel is a specialized material designed for the demanding conditions of deep sour service wells. Its controlled yield strength, coupled with compliance with API 5CT and NACE standards, makes it a robust choice for applications where H2S is present.
