USS GT80S Steel Grade

2024-04-23 21:21 985 views

USS GT80S Steel Grade for Severe Sour Service Wells

USS GT80S is a proprietary controlled yield strength steel grade, specifically engineered for use in severe sour service wells where the resistance to sulfide stress cracking (SSC) is paramount. This high-performance steel grade is manufactured to stringent standards to ensure reliability and longevity in harsh downhole conditions.

Mechanical Properties

  • Minimum Yield Strength: 80,000 psi
  • Maximum Yield Strength: 95,000 psi
  • Minimum Tensile Strength: 95,000 psi
  • Maximum Hardness: 23.0 HRC

The mechanical properties of USS GT80S are tailored to provide exceptional strength and ductility, making it suitable for applications in severe sour service environments.

Standards and Testing

Inspection, testing, and dimensional criteria for USS GT80S steel grade conform to the API L80 specification, ensuring that the steel meets the industry's quality and performance benchmarks.

NACE (SSC) qualification testing, following Method A, is specified at a threshold stress of 90% of the specified minimum yield strength. This testing ensures the steel's resistance to sulfide stress cracking, which is critical for the safe operation of sour service wells.

API C90 couplings are utilized on threaded and coupled products made from USS GT80S steel to guarantee structural integrity and compatibility with industry-standard connections.
