①d=圓棒直徑昔黍；s=方、六角棒材截面寬度给措，矩形棒材的厚度兆送；t=管材壁厚；單位/mm
②A炮罩、A50-標(biāo)距
*性能可通過軋制淬火獲得棺距。
? 351-固溶，通過拉伸控制量(設(shè)定1%~3%)消除應(yīng)力+自然時效。拉伸后的產(chǎn)品不再矯直榴蜻。(solution heat-treated, stress-relieved by stretching a controlled amount (permanent set 1 %,to 3 %) and naturally aged. The products receive no further straightening after stretching.)
? T3510-固溶秕肌，通過拉伸控制量(設(shè)定0.5%~3%對軋管)消除應(yīng)力+自然時效。拉伸后的產(chǎn)品不再矯直瞎喉。(solution heat-treated, stress-relieved by stretching a controlled amount (permanent set 1 %,to 3 %) and naturally aged. The products receive no further straightening after stretching.)
? T3511-與T3510相同好唯，除了在拉伸后允許輕微矯直以符合標(biāo)準(zhǔn)公差。(same as T3510 except that minor straightening is allowed after stretching to comply with standard tolerances)
