网上经常有人问,BK,BKW,BKS,utf-8,NBK 是什么意思,我想看了这个大家应该明白了。

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()

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()

最后热处理之后进行小变形量的冷加工, 对雷火电竞平台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

utf-8(+A)

The last Cold forming process is followed by annealing in a controlled atmosphere.

退火

最后冷加工之后,雷火电竞平台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,雷火电竞平台在保护气体下进行正火.
