How is the quality of carbon steel flanges determined?

Carbon steel flanges are precise in shape and size, with low machining and low cost. However, cast flanges will have holes, cracks and impurities, and the internal structure of the casting is poor. The advantage is that it can have more complex shapes and be produced at low cost. Plain carbon steel flanges are less susceptible to rust and have a denser structure because they have a lower carbon content than cast flanges. They can withstand shear and tensile forces better and have better mechanical properties than forged flanges. Ordinary carbon steel flanges and casting flanges are difficult to distinguish from each other by appearance alone.

When buying carbon steel flanges, you must choose them according to the environment of use. Not only should it be cheap, but also with it in mind. The flange should not be stored directly on the ground. Place some moisture-proof pads on the ground and then arrange the flanges neatly. When placing them, leave a channel between the carbon steel flanges and the carbon steel flanges. It acts as a ventilation and also facilitates the transportation of carbon steel flanges. Different materials should be stored and labeled separately, the same material, different types and specifications should be stored separately, and the corresponding markings should be stacked neatly to avoid bruising.
