Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.Annealed    GBK(+A)The last Cold forming process is followed by annealing in a controlled atmosphere.Normalized   NBK(+N)The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.Delivery TimeWithin 35-50 days from receiving depositPayment Term100% L/C at sight or 30% deposit, 70% balance against copy of B/LUsage/ApplicationPipes for high pressure boiler
