①d=圓棒直徑鸭叙;s=方觉啊、六角棒材截面寬度,矩形棒材的厚度沈贝;t=管材壁厚杠人;單位/mm
②A、A50-標距
*性能可通過軋制淬火獲得宋下。
? O-退火
? H111-在隨后的拉伸或應變中經(jīng)過退火和輕微應變硬化(小于H11)嗡善。(annealed and slightly strain-hardened (less than H11 ) during subsequent operations such as stretching or straitening)
? T3510-固溶,通過拉伸控制量(設定0.5%~3%對軋管)消除應力+自然時效岖酸。拉伸后的產(chǎn)品不再矯直皆坚。(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,除了在拉伸后允許輕微矯直以符合標準公差币遮。(same as T3510 except that minor straightening is allowed after stretching to comply with standard tolerances)
