Alloy Steel WP12 Pipe Fittings are top-notch components crafted for high-temperature and high-pressure piping systems. Made from a blend of chromium and molybdenum alloy steel, these fittings boast impressive strength, durability, and resistance to thermal stress and corrosion. WP12 fittings are designed with precision and feature smooth finishes, ensuring dependable connections and leak-proof performance in critical piping applications. They’re commonly found in industries where safety, long-term reliability, and efficiency are paramount, providing a sturdy solution for high-pressure steam, chemical, and oil & gas systems.
WP12 pipe fittings of Alloy Steel are predominantly made of molybdenum (0.90–1.10%) and chromium (2.0–2.5%) that increases its strength, hardness, and corrosive resistance at high temperatures. The steel is also constituted of trace quantities of carbon (0.05–0.15%), manganese, and silicon. WP12 also possesses excellent mechanical properties, such as tensile strength of (415–585 MPa), yield strength (205 MPa), and minimum elongation (20%). All these properties offer great performance in high-pressure and high-temperature environments, and therefore WP12 is ideally capable of being used in critical application areas in chemical processing, power generation, and boiler applications. It also has very good thermal fatigue and stress cracking resistance.
