精密鋼管的交貨狀態
Designation Symbol Description
交貨狀態 代號 說明
Cold finished (hard) BK(+C) Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
冷加工(硬) 最后冷加工之后不進行熱處理, 從而管子只可能進行很小的變形。
Cold finished (Soft) BKW
(+LC) The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)
冷加工(軟) 最后熱處理之后進行小變形量的冷加工, 對鋼管再加工時允許有限的冷變形(例如: 彎曲, 擴口)
Cold finished and stress-relieved BKS(+SR) Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.
冷加工后消除應力退火 最后冷加工后在Acl點以下進行退火, 以消除冷加工應力。
Annealed GBK(+A) The last Cold forming process is followed by annealing in a controlled atmosphere.
退火 最后冷加工之后,鋼管在保護氣體下進行完全退火。
Normalized NBK(+N) The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
正火 最后冷加工之后,鋼管在保護氣體下進行正火。 www.tjyggs.com www.bxgdy.com www.hryygt.com
