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-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。AnnealedGBK(+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。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,钢管在保护气体下进行正火。您可能还感兴趣的产品:山东精密钢管厂|聊城精密钢管厂|喀什精密钢管厂|
