Alloy 20 consists of nickel (32–38%), chromium (19–21%), and iron (the base), along with molybdenum, copper, and niobium. It offers a tensile strength of about 620 MPa, a yield strength of at least 240 MPa, and excellent corrosion resistance in many acidic environments. The alloy works particularly well with hot sulfuric acid, phosphoric acid, and fluids that contain chlorides. Alloy 20 pipe fittings hold their shape and strength under high temperatures and are easy to weld and form.
