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(jìn)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-relievedBKS（+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(yīng)力退火最后冷加工后在Acl點以下進(jìn)行退火， 以消除冷加工應(yīng)力。AnnealedGBK（+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(jìn)行完全退火。NormalizedNBK（+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(jìn)行正火。您可能還感興趣的產(chǎn)品：山東精密鋼管廠|聊城精密鋼管廠|喀什精密鋼管廠|
