The NACE Standard TM0177-96 describes four different types of stress corrosion cracking tests which do not necessarily lead to the same ranking of steels for OCTG. Our paper presents the results of corrosion tests according to method A and D for an OCTG order in grade T95.
Keywords: OCTG, grade T95, Coupling, Casing, DCB-Test, Tensile test, Microstructure, DCB specimen preparation, pH of test solution
