WP91 Alloy Steel Pipe Fittings are produced from a high-performance alloy that is basically 9% chromium and 1% molybdenum with minute vanadium contents, which improves its oxidation and corrosion resistance at elevated temperatures. The alloy is chemically formulated to resist aggressive environments, exhibiting high resistance to creep and thermal fatigue. Mechanically, WP91 fittings have good tensile strength, high yield strength, and good resistance to creep and stress rupture under high-temperature service. Physically, the fittings retain good thermal conductivity and stability, making them durable and dependable in high-risk applications like power plants, refineries, and boilers.
