ASTM A789/ A790 Uns S31803 S32750 S32760 S2205 Seamless Stainless Steel Pipe
ASTM A789/A790 is a specification that covers duplex stainless steel seamless and welded pipes for general corrosive service. These pipes are widely used in various industries such as chemical processing, oil and gas, pulp and paper, marine engineering, and more. The duplex stainless steel used in these pipes combines the best features of austenitic and ferritic stainless steels, resulting in a material that has excellent corrosion resistance, high strength, and good weldability.
UNS S31803, S32750, S32760, and S2205 are some of the most popular grades of duplex stainless steel used in ASTM A789/A790 seamless stainless steel pipes. Each of these grades has unique properties that make them suitable for different applications.
UNS S31803, also known as 2205, is a widely used grade of duplex stainless steel. This grade contains 22% chromium, 5% nickel, and 3% molybdenum, as well as small amounts of other elements such as nitrogen and carbon. UNS S31803 has good corrosion resistance and high strength, making it suitable for a range of applications such as chemical processing, oil and gas, and more.
UNS S32750, also known as 2507, is a higher grade of duplex stainless steel that contains 25% chromium, 4% molybdenum, and 7% nickel, as well as small amounts of other elements such as nitrogen and carbon. UNS S32750 has excellent resistance to pitting, crevice corrosion, and general corrosion, and it is often used in applications where high strength and good corrosion resistance are required.
UNS S32760, also known as Zeron 100, is a higher grade of duplex stainless steel that contains 25% chromium, 7% molybdenum, and 3% tungsten, as well as small amounts of other elements such as nitrogen and carbon. UNS S32760 has even higher strength and better corrosion resistance than UNS S32750, making it suitable for even more demanding applications.
ASTM A789/A790 uns S31803, S32750, S32760, and S2205 seamless stainless steel pipes are known for their excellent corrosion resistance, high strength, and good weldability. These pipes are widely used in various industries such as chemical processing, oil and gas, pulp and paper, marine engineering, and more.
One of the key advantages of duplex stainless steel is its excellent resistance to corrosion. This type of steel is particularly resistant to pitting and crevice corrosion, which are common problems in many industries. This resistance to corrosion makes ASTM A789/A790 uns S31803, S32750, S32760, and S2205 seamless stainless steel pipes ideal for use in harsh environments where corrosion is a concern.
In addition to their corrosion resistance, ASTM A789/A790 uns S31803, S32750, S32760, and S2205 seamless stainless steel pipes are also known for their high strength. This makes them suitable for use in applications where high pressure or heavy loads are a concern. Furthermore, these pipes are also known for their good weldability, which makes them easy to work with and suitable for a range of fabrication processes.
When it comes to selecting the right type of duplex stainless steel pipe for your application, there are a few factors to consider. Firstly, you need to consider the environment in which the pipe will be used, as this will impact the corrosion resistance required. You should also consider the strength requirements of your application, as well as any fabrication processes that will be required.
