Filiz Steel, based in Istanbul, Turkey, stands out as a leading manufacturer and supplier of **Alloy Steel WP12 Pipe Fittings**, catering to both local and global markets. Renowned for its engineering excellence and commitment to quality, Filiz Steel provides WP12 fittings that adhere to the strict standards set by ASTM and ASME. These fittings are designed to be durable, high-performing, and capable of withstanding extreme temperatures and pressures. With state-of-the-art production facilities and a strong focus on customer satisfaction, Filiz Steel serves industries like power generation, petrochemicals, and refineries, delivering reliable and cost-effective piping solutions tailored for demanding applications.
Alloy Steel WP12 Pipe Fittings primarily consist of chromium (1.0–1.5%) and molybdenum (0.44–0.65%), with iron as the main element. This unique composition grants them exceptional high-temperature strength, oxidation resistance, and structural stability under pressure. Typically, these fittings boast a minimum tensile strength of 415–585 MPa, a yield strength of at least 205 MPa, and an elongation of 20% or more. These impressive mechanical properties, along with good weldability and creep resistance, make WP12 an excellent choice for components that face elevated temperatures over extended operational periods in critical service environments.

Alloy Steel WP12 Pipe Fittings find extensive use in high-temperature and high-pressure piping systems, especially in power plants, petrochemical facilities, and oil refineries. Their strong mechanical properties and resistance to thermal fatigue make them perfect for applications in heat exchangers, superheaters, reheaters, and boiler components. WP12 fittings are also well-suited for steam and gas processing systems where consistent strength and corrosion resistance are essential. Their versatility in welding and forming processes further enhances their usability in complex and custom-engineered applications.
