THIS CHAPTER PRESENTS chemical and mechanical properties of two J-55 casings selected to have significantly different yield strengths. The chemical composition and tensile properties of the tested casings met the specification requirements for both J-55 and K-55 casing grades. Consequently, the results of the investigation are equally applicable to both grades. Also presented are the results of burst tests that were conducted at Battelle  on short sections of these casings containing milled notches and the results of a failure analysis of the tested sections conducted at the U.S. Steel Technical Center. Finally, the significance of the results to API Charpy V-notch requirements for J-55 and K-55 casings are discussed.
