Oil Country Tubular Goods (OCTG)

United States Steel Corporation manufactures more than 1,500 different types of steel, many of them formulated in close consultation with our customers. Our annual capacity for tubular products is 2.8 million net tons, much of it destined for use by the oil and natural gas industries. Our facilities can provide a wide range of high-quality, high-strength, low-residual, formable steels with unique properties that are virtually impossible to produce using any other method.

Notes: 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 T95. Performance properties are the same as for API grade T95.

Hardness testing is conducted as required for API T95, with the exception of frequency (Casing and Non-Upset Tubing - First, last and every tenth joint in between; Upset Tubing - First, last and every 25th joint in 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 percent specified minimum yield strength.
