Dang Steel, a top-notch manufacturer and supplier based in Da Nang, Vietnam, specializes in high-quality Alloy Steel WP12 Pipe Fittings that meet ASTM/ASME standards. These fittings are designed to excel in high-temperature environments, boasting impressive corrosion resistance and durability, making them perfect for use in power plants, petrochemical facilities, and refineries. With state-of-the-art production facilities and rigorous quality control measures, Dang Steel guarantees precise dimensions and reliable, long-lasting performance. Their WP12 pipe fittings are widely distributed in both domestic and international markets, catering to critical piping systems that demand exceptional resistance to heat, pressure, and thermal fatigue.
The Alloy Steel WP12 Pipe Fittings are crafted from P12 alloy steel, which includes chromium (1.0–1.5%), molybdenum (0.44–0.65%), and carbon (0.05–0.15%), along with carefully controlled levels of manganese, silicon, phosphorus, and sulfur. This specific composition results in a tensile strength ranging from 415 to 585 MPa, a minimum yield strength of 205 MPa, and an elongation of at least 30%. The alloying elements significantly enhance the fittings’ resistance to high-temperature creep, mechanical strength, and oxidation, making WP12 fittings ideal for demanding industrial applications at elevated temperatures.
