These Alloy 20 Buttweld Fittings are primarily made from iron, featuring significant amounts of nickel (32–38%), chromium (19–21%), and copper (1–3%), along with molybdenum and trace elements that boost corrosion resistance. This unique alloy composition offers remarkable durability in environments exposed to strong acids and oxidizing agents. The fittings boast high tensile strength, excellent toughness, and good ductility, making them resilient against stress and pressure, even at elevated temperatures. Their well-balanced makeup ensures superior weldability and formability, enabling them to perform effectively in harsh conditions while preserving mechanical integrity and structural stability over long service periods.
