①d=圓棒直徑;s=方、六角棒材截面寬度,矩形棒材的厚度;t=管材壁厚;單位/mm
②A、A50-标距
*性能可通過軋制淬火獲得。
ⓖ T6510-固溶,通過拉伸控制量(設定0.5%~3%對軋管)消除應力+人工時效。拉伸後的產品不再矯直。(solution heat-treated, stress-relieved by stretching a controlled amount (permanent set 0,5% to 3 % for drawn tube) and then artificially aged. The products receive no further straightening after stretching.)
ⓗ T6511-與T6510相同,除了在拉伸後允許輕微矯直以符合标準公差。(same as T6510 except that minor straightening is allowed after stretching to comply with standard tolerances)
ⓘ T73510-固溶,通過拉伸控制量(設定0.5%~3%)消除應力+人工過時效,以獲得最佳抗應力腐蝕性能。拉伸後的產品不再矯直。(solution heat-treated, stress-relieved by stretching a controlled amount (permanent set 0,5 % to 3 % ) and then artificially overaged in order to achieve the best stress corrosion resistance The products receive no further straightening after stretching.)
