Duplex steel flanges are made from work hardenable alloys that are exceptionally corrosion-resistant. A blend of austenite and ferrite phases makes up their composition. As a result, qualities of both austenitic and ferritic stainless steel can be found in duplex steel flanges. While duplex stainless steel is resistant to stress corrosion cracking, it is not as robust as ferritic stainless steel to this type of assault. The corrosion resistance of the least resistant duplex stainless steel, on the other hand, is higher than that of the most generally used stainless steel grades, 304 and 316. Duplex stainless steel is extremely corrosion resistant. They have high resistance to intergranular corrosion. Even in chloride and sulfide environments, Duplex steel flanges exhibit very high resistance to stress corrosion cracking.
Duplex steel flanges are more resistant to saltwater than grade 316. It's nitrogen-enhanced stainless steel that was created to solve the 300 series stainless steel's corrosion resistance difficulties.
Duplex steel flanges are frequently utilized in a variety of applications, including storage tanks, water heaters, and bridges. They are mostly used in situations when the austenitic grades might fail prematurely. Other applications include chemical processing, transport and storage, Oil and gas exploration and offshore rigs, Oil and gas refining, Pollution control equipment, Pulp & paper manufacturing, and Chemical process plant

As the name suggests, stainless steel flanges are flanges made of an alloy called stainless steel.
Here is why stainless steel flanges are worth your investment:
Corrosion resistance :
Corrosion is a major problem for clients using flanges due to chemicals and environmental factors. Therefore, it is ideal to choose stainless steel flanges that can withstand these conditions. Stainless steel is a great choice as it is highly resistant to corrosion.
Durability:
Stainless steel is one of the most durable alloys and can withstand harsh environmental conditions.
Tolerance to extreme temperatures:
Flanges made of stainless steel can withstand high temperatures. Some grades can withstand scaling and can maintain their strength even at very high temperatures, while others show excellent durability at extremely low temperatures.
Aesthetics:
Stainless steel flanges are available in a variety of surface finishes which gives them an aesthetic look. It is easy to clean and maintain, resulting in high quality, attractive appearance.
Stainless steel flanges are available in a wide variety of grades of stainless steel. Each grade differs in chemical composition and has different properties. There are various grades of stainless steel flanges available to suit the client's requirements. One must put its intended applications into consideration when choosing the grade of stainless steel flange to use. For example liquids, gases, etc.)

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.
