①d=圓棒直徑;s=方椭肝、六角棒材截面寬度茬蒿,矩形棒材的厚度;t=管材壁厚玩困;單位/mm
②A附扭、A50-標距
*性能可通過軋制淬火獲得。
? T3510-固溶连嘹,通過拉伸控制量(設定0.5%~3%對軋管)消除應力+自然時效颈有。拉伸后的產(chǎn)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 naturally aged. The products receive no further straightening after stretching.)
? T3511-與T3510相同疲狼,除了在拉伸后允許輕微矯直以符合標準公差吁沉。(same as T3510 except that minor straightening is allowed after stretching to comply with standard tolerances)
