Casting forging ratio can withstand higher shear and tensile strength. Casting advantage is that you can come up with a more complex shape, the cost is relatively low; forging advantage is that even within the organization, there is no casting porosity, inclusions and other harmful defects; loose cover flange 20 # _20 # flange _ Cangzhou Bohai made Cangzhou Bohai Pipe Fittings Limited.
