Grades 2H,

11、 7H, 16H, and 26H areintended primarily for pressure vessel use.The H grades were added in response to a user association request basedon its study of over 5200 commercial Grade 2, 7, 16, and 26 test reports,where over 99 % met the 58 ksi minimum UTS.1.2 The values stated in inch-pound units are to
