Product Description

The cost of rolling the flange is lower than forging. But some of the large flange is not forging out. Such products are mostly weight with the theoretical weight, in the calculation, is not the waterline, mouth, bolt holes, chamfer weight loss. The price of flat products is lower, but if there is a process of processing the dovetail and the like, the price of the large flange will be higher. The theoretical weight is calculated by the following formula
