The shape and size of ordinary carbon steel flanges are precise, with a small amount of processing and low cost. However, cast flanges will have holes, cracks, and impurities, and the internal structure of the casting is poor. Its advantage is that it can have more complex shapes and lower production costs.

OrdinaryCarbon Steel FlangeThe carbon content is lower than that of cast flanges, making it less prone to rust and with a dense structure. It can withstand shear and tensile forces better than forged flanges, and its mechanical properties are also better.
OrdinaryCarbon Steel FlangeIt is difficult to distinguish between forged and cast flanges just by appearance. Here are a few methods for your reference:
First is the price comparison. Cast flanges on the market are cheaper to produce, while forged flanges are more expensive than pure forged.
The second is to conduct destructive testing to separate the flanges. Castings have sand holes, while pure forgings do not. Cast-forged flanges sometimes have cracks.
The third is to look at the tolerances and surface finish of the flanges; cast flanges usually havenegative tolerances of 1-5mm, irregular edge chamfers, no burrs in the holes, and forged flanges have smaller tolerances.
The fourth is weighing. For flanges of the same size, cast flanges will be lighter than forged flanges.
PurchaseCarbon Steel Flangeshould be based on the usage environment. They should not only be cheap but also meet the requirements. Flanges are also known as flangeddiscs, which can be divided into carbon steel flanges, stainless steel flanges, and alloy steel flanges based on their materials.
Carbon Steel FlangeCarbon steel flanges contain carbon steel. According to the content of various trace elements, they can be divided intoA105 material, Q235 material, 16MN material, 20# material, etc., and can be divided into forged flanges, cast flanges, mid-plate rolling, and mid-plate cutting based on the production process. Among them, forged flanges have good quality, followed by rolling and casting. Since carbon steel flanges do not have anti-corrosion functions, the main anti-corrosion treatments include oiling, painting, and galvanizing.
