API 5CT R95

API 5CT R95

API 5CT R95 has the same yield strength range and tensile strength as API 5CT T95 but does not need SSC or hardness testing; hence, it is typically not suitable for use in condensate wells due to the lack of hardness limits. API 5CT R95 steel is a more cost-effective alternative to API 5CT T95 steel in wells without the risk of sulfide stress cracking.

API 5CT version 9, chapter “Manufacturing Method and Chemical Composition Requirements,” eliminated the C95 steel grade and raised the R95 steel grade. TUSPIPE is a leading producer and supplier of API 5CT casing and tubing. We provide a comprehensive selection of API 5CT R95 oilfield casing pipe and API 5CT R95 type 1 tubing, as well as casing couplings, perforated pipe, and more.

a) The molybdenum content for Grade C90 Type 1 has no minimum tolerance if the wall thickness is less than 17.78 mm.

b) The carbon content for R95 may be increased up to 0.55 % maximum if the product is oil-quenched.

c) The molybdenum content for T95 Type 1 may be decreased to 0.15 % minimum if the wall thickness is less than 17.78 mm.

NL = no limit. Elements shown shall be reported in product analysis.
