Vishal Flanges is a well-respected manufacturer and supplier of Alloy 20 Lap Joint Flanges, located in Delhi, India. They specialize in providing corrosion-resistant solutions that are perfect for tough industrial settings. Alloy 20 is a unique blend of nickel, iron, and chromium, with added copper and molybdenum, specifically crafted to withstand acid attacks, especially from sulfuric acid. These lap joint flanges are perfect for systems that need to be easily taken apart and realigned. Vishal Flanges ensures that their products meet international quality standards and dimensions, guaranteeing durability, excellent corrosion resistance, and cost-effective upkeep. Their Alloy 20 Lap Joint Flanges find extensive use in the chemical, pharmaceutical, petrochemical, and food processing industries.
Alloy 20 Lap Joint Flanges are made from a special alloy that includes nickel, chromium, molybdenum, and copper, which gives them excellent resistance to corrosion, especially in sulfuric acid environments. These flanges are designed with high tensile strength, impressive yield strength, and outstanding flexibility, ensuring they last over time. Their exceptional weldability and machinability make them perfect for applications that require frequent disassembly and reassembly. With a sturdy structure and excellent performance under high pressure and temperature, Alloy 20 Lap Joint Flanges are well-suited for demanding industrial applications.
Alloy 20 Lap Joint Flanges are made up of nickel (32–38%), iron (the rest), chromium (19–21%), molybdenum (2–3%), copper (3–4%), and trace amounts of niobium. This mix provides exceptional resistance to sulfuric acid, pitting from chlorides, and stress corrosion cracking. These flanges boast a tensile strength of about 551 MPa, a yield strength of 241 MPa, and impressive elongation and toughness. The alloy retains its mechanical strength even in highly corrosive and mildly oxidizing conditions. Alloy 20 flanges are also recognized for their good weldability and formability, making them ideal for complex fabrication and installation tasks.
