Casing Pipe P110-28Cr
API H40
Minimum Yield Strength: 40,000 psi
Maximum Yield Strength: 80,000 psi
Minimum Tensile Strength: 60,000 psi
Notes: General purpose pipe manufactured to API specification 5CT.
API J55
Minimum Yield Strength: 55,000 psi
Maximum Yield Strength: 80,000 psi
Minimum Tensile Strength: 75,000 psi
Hardness Requirement: None
Notes: General purpose pipe manufactured to API specification 5CT. Similar to K55 except the minimum tensile strength is lower. Usually, this grade is used in tubing applications.
API K55
Minimum Yield Strength: 55,000 psi
Maximum Yield Strength: 80,000 psi
Minimum Tensile Strength: 95,000 psi
Hardness Requirement: None
Notes: General purpose pipe manufactured to API specification 5CT. Usually, this grade is used in casing applications
API L80
Minimum Yield Strength: 80,000 psi
Maximum Yield Strength: 95,000 psi
Minimum Tensile Strength: 95,000 psi
Hardness Requirement: 23 HRC maximum
Notes: Manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. L80 is usually used in wells with sour (H2S) environments.
API N80 (or N80 Q&T)
Minimum Yield Strength: 80,000 psi
Maximum Yield Strength: 110,000 psi
Minimum Tensile Strength: 100,000 psi
Hardness Requirement: None
Notes: General purpose pipe manufactured to API specification 5CT.
API Normalized N80
Minimum Yield Strength: 80,000 psi
Maximum Yield Strength: 110,000 psi
Minimum Tensile Strength: 100,000 psi
Hardness Requirement: None
Notes: A lower-cost alternative to standard Quench and Tempered API N80 (walls less than 0.500 inch). Inspection, testing and dimensions are in accordance with API 5CT for grade N80. Charpy v-notch impact test absorbed energy results meet API SR16 and are lower than Quench and Tempered N80.
API C90
Minimum Yield Strength: 90,000 psi
Maximum Yield Strength: 105,000 psi
Minimum Tensile Strength: 100,000 psi
Hardness Requirement: 25.4 HRC maximum
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, sulphide 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.
API T95
Minimum Yield Strength: 95,000 psi
Maximum Yield Strength: 110,000 psi
Minimum Tensile Strength: 105,000 psi
Hardness Requirement: 25.4 HRC maximum
Notes: API controlled yield strength grade, the same as API 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 percent of specified minimum yield strength.
API P110
Minimum Yield Strength: 110,000 psi
Maximum Yield Strength: 140,000 psi
Minimum Tensile Strength: 125,000 psi
Hardness Requirement: None
Notes: API grade for general use in deep wells. This grade is not generally considered suitable for sour condensate wells.
API Q125
Minimum Yield Strength: 125,000 psi
Maximum Yield Strength: 150,000 psi
Minimum Tensile Strength: 135,000 psi
Hardness Requirement: No limit specified - Hardness variation requirement
Notes: 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).
V150
Minimum Yield Strength: 150,000 psi
Maximum Yield Strength: 180,000 psi
Minimum Tensile Strength: 160,000 psi
Hardness Requirement: None
Steel grade for use in deep well applications. Dimensions and inspection are in accordance with API 5CT Group 3 requirements.

INSPECTION CLASSIFICATIONS
New Tubing/Casing
(and Plain End Drill Pipe)
*White Band: suitable for all inspections performed (incl. min. 87.5% body wall).
*Yellow Band: Repairable reject. 87.5% body wall remaining after repair. Locate bands on either side and circle around defect.
*Blue Band: Imperfections of undetermined depth. Identified as above.
*Red Band: Defective length. Identified as above. Body wall defects must be cut out of tube.
Damaged pin or box ends marked with red bands next to pin or on coupling
