What should be paid attention to in the processing of stainless steel flange?

The flange with Jerry built materials is generally cast, and there are many problems, such as shrinkage and porosity of poor flange.

Common carbon steel and stainless steel flanges are mostly made of steel plates, but also cast and forged.

In the process of processing, stainless steel needs to be processed at low speed due to sticking knife, which is slower, but the processing amount is smaller than that of carbon steel.

Generally speaking, stainless steel flange will not rust, but it will also rust when other changes occur.

For example, the impact with other carbon steel, the change of surface lattice in case of welding, the oxidation in case of water and air, the oxidation in case of chemicals containing a lot of chloride ions, etc.

A flange is the part that connects the pipe to the pipe. There are holes on the flanges and the bolts make the two flanges close. The flanges is sealed with a cushion. Flange can be divided into threaded connecting flanges and welding flanges. Stainless steel is usually divided into 304, 304L, 316, 321, 316L and others.
