OCTG PRODUCTS
FEATURES
As a contributing member of the American Petroleum Institute (API) since 1925, U. S. Steel Tubular Products manufactures a comprehensive range of monogrammed API 5CT OCTG grades.
API H40 is a general purpose pipe manufactured to API specification 5CT.
API J55 is a general purpose pipe manufactured to API specification 5CT. Similar to K55 except the minimum tensile strength is lower.
API K55 is a general purpose pipe manufactured to API specification 5CT. Usually, this grade is most often used in casing applications.
API N80 Type 1 is a lower cost alternative to standard Quench and Tempered API N80 (walls less than 0.500 inch). Charpy V-notch impact test absorbed energy results meet API SR16 and are lower than quenched-and-tempered N80.
API N80Q is a general purpose pipe manufactured to API specification 5CT using a quench and temper process.
API L80 is manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. L80 is often used in wells with sour (H2S) environments.
API C90 is an API controlled yield strength grade generally for use in sour condensate wells. Extensive hardness testing is required along with Sulfide Stress Corrosion Cracking (SSCC) testing per NACE Standard TM-0177, Method A. The minimum threshold stress required is 80% of specified minimum yield strength.
API R95 is an API grade with the same strength range as T95 and USS C95, but without a hardness requirement. This grade is not generally considered for use in sour condensate wells since no hardness restrictions or testing are required and no Sulfide Stress Corrosion Cracking (SSCC) testing is required.
PI T95 is an API controlled yield strength grade, the same as API C95 and USS C95. Generally for use in sour condensate wells. Extensive hardness testing is required along with SSCC testing per NACE Standard TM-0177, Method A. The minimum threshold stress required is 80% of specified minimum yield strength.
API P110 is an API grade for general use in deep wells. This grade is not generally considered suitable for sour condensate wells.
API C110 is a controlled yield strength grade generally used in deeper sour condensate wells. SSCC testing is required for each heat to meet a threshold stress of 85% of specified minimum yield strength.
API Q125 is an API grade for deep well service, not generally for use in sour condensate wells. Quadrant hardness testing is required without any specified limits other than the variation between readings. Impact testing is required for each heat and/or lot. NDT inspection is required with two methods of inspection; typically EMI and UT are performed on this product.

FEATURES
In addition to the existing family of API 5CT grades, U. S. Steel Tubular Products manufactures proprietary OCTG grades. These grades come with tailored specifications aimed at minimizing costs, reducing lead times, and meeting distinct performance criteria for sour service applications.
USS N80N is a lower cost, non-heat treated alternative to standard Quench and Tempered API N80 (for walls less than 0.500 inch). USS N80N meets all the requirements of API N80 with the exception of Charpy V-notch impact toughness.
USS C90 is a proprietary, restricted yield strength U. S. Steel grade for use in sour condensate wells. Resistance to sulfide stress cracking is achieved by precise controls of chemical composition, heat treatment, and hardness levels.Inspection requirements and dimensional tolerances are in accordance with API 5CT for grade C90.

Hardness testing is conducted as required for API T95, except for frequency (casing and non-upset tubing first and last and every tenth joint in between) upset tubing (first and last and every 25th joint between). To reduce order lead-time, sulfide stress corrosion cracking (SSCC) testing is not required for every order. If required by the customer, SSCC testing can be performed to U. S. Steel Standard Mill Practice P-1004 (NACE Standard TM-0177, Method A) with a guaranteed minimum threshold stress of 85% of specified minimum yield strength.
