Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding).Cold finished and stress-relieved+SRBKSHeat 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.Annealed+AGBKThe last cold forming process is followed by annealing in a controlled atmosphere.Normalized+NNBKThe last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.Dimension: OD4-60MM,WT0.5-8MM, Length: up to 6m.Company ProfileFrom 1989 to now, Kingmetal Steel focus on manufacturing and distributing pipeline products including piping, fitting, flange, valve and fastener in stainless, carbon, alloy and duplex steel.
