Specification requirements for sulfide stress cracking resistance of low alloy steel tubulars vary widely throughout the industry. The effect of differences in test frequency is shown in terms of the amount of non-conforming material and probability of lot acceptance. The TM0177 test method A is shown to be inferior as a quality control test to both methods B and D. Both users and manufacturers of Oil Country Tubular Goods could benefit from a reexamination of the basis for such test requirements.
