These Alloy Steel Pipe Flanges have a variety of amazing qualities to provide, like Abrasive coating, Tamper proof, Protected, Adequate raw material, Efficient, Perfect finish, Longer life, Accurate dimension, and others. We also provide these products in customized sizes and forms to our clients. Flanges are forged or cast rings that are used to connect parts of a pipe or any type of machine requiring an intermediate connecting point. Aside from carbon, this alloy steel includes significant amounts of Nickel, Manganese, Chromium, Silicon, Tungsten, Vanadium, and Molybdenum. Furthermore, they are fortified with trace amounts of elements like sulphur, silicon, manganese, and phosphorous, which aid in boosting hardness, strength, chemical resistance, and other properties. 

The Solution annealing on these flanges is not necessary because the mechanical properties are shown in the built state. These Alloy Steel Flanges are made from chromium, and they are used to resist scaling at temperatures greater than 1100 degrees.

These flanges can withstand wind exposure, pollution from industrial processes, and elevated temperatures, which are closer to the sea, which is the leading cause of saltwater pollution. Alloy Steel Flanges have the highest chromium content, which makes them beneficial to wet corrosion resistance. These flanges also resist scaling at high temperatures.  

Once these flanges have been fabricated, they are forwarded for testing, where numerous destructive tests are performed to ensure that they are free of damage and of the highest quality. We value the packing among these products since providing a flawless product is vital to us.
