1. Materials: The chemical compositions have been carefully determined to provide resistance to sulfide stress corrosion as well as to insure complete through wall hardening.
2.Heat Treatment: Quenching and Tempering are conducted under rigid temperature control to assure homogeneous physical properties and microstructures.
3.Micro Structure: These grades exhibit fully tempered martensite which is considered to be the most desirable for resistance to sulfide stress corrosion cracking.
A full length non destructive inspection is performed in accordance with API 5CT for external and internal, longitudinal and transverse defects with a standard notch depth equal to 5% of the specified wall thickness.
