精密钢管的交货状态
Designation Symbol Description
交货状态 代号 说明
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) 最后冷加工之后不进行热处理, 从而管子只可能进行很小的变形。
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(软) 最后热处理之后进行小变形量的冷加工, 对钢管再加工时允许有限的冷变形(例如: 弯曲, 扩口)
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.
冷加工后消除应力退火 最后冷加工后在Acl点以下进行退火, 以消除冷加工应力。
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,钢管在保护气体下进行完全退火。
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,钢管在保护气体下进行正火。 www.tjyggs.com www.bxgdy.com www.hryygt.com
