In this paper sulfide stress cracking case histories of 12 Cr and 17-4PH stainless steel tubing hangers are presented along with the results of NACE Standard TM0177 laboratory tests performed on the failed material. Even though the hangers both met NACE Standard MR0175-88 hardness requirements, failure still occurred. These failures demonstrate the limitations of these alloys in high H{sub 2}S service even when MR0175 requirements are met. The need for better usage guidelines is discussed.
