SS Welded Tubes made from Alloy 20 stand out as a top choice. With a diameter of 8.0 mm and a thickness of 1.6 mm, these tubes are widely used in a variety of demanding applications. SS seamless tubes made from Alloy 20 with a diameter of 8.0 mm and thickness of 1.6 mm are an ideal solution for industries that demand both high corrosion resistance and durability. Whether you’re working in chemical processing, pharmaceuticals, or any industry where strong acids and corrosive environments are prevalent, Alloy 20 seamless tubes provide the reliability and longevity you need.
Alloy 20, also known as Carpenter 20 or Nickel-Iron-Chromium Alloy, is a highly corrosion-resistant metal specifically designed to combat acid attacks, particularly sulfuric acid. It is a nickel-based alloy that contains a small percentage of copper and molybdenum for added resistance to pitting and crevice corrosion. It also offers protection against stress-corrosion cracking, which makes it perfect for a variety of aggressive environments.
