Alloy 20 Orifice Flanges are primarily made up of nickel (32–38%), chromium (19–21%), and iron (the balance), along with molybdenum (2–3%), copper (3–4%), and niobium for stabilization. This unique blend gives them exceptional resistance to sulfuric acid, chlorides, and other aggressive chemicals. On the mechanical side, these flanges boast a tensile strength of around 551 MPa, a yield strength of 241 MPa, and an elongation of 30–35%. Their forged design enhances toughness, hardness, and durability, making them ideal for high-pressure, high-temperature operations where precise flow control and corrosion resistance are essential.
