Alloy 20 is an austenitic, nickel-iron-chromium-molybdenum alloy with the addition of copper. This combination makes it preferable in applications involving sulfuric, phosphoric, and nitric acids. The chromium and molybdenum content provide good pitting and crevice corrosion resistance.

Alloy 20 is a high-performance nickel-iron-chromium alloy that offers superior corrosion resistance in aggressive media, such as sulfuric acid, and shows suitable resistance in phosphoric acid, nitric acid and aqueous salt solutions.

Alloy Steel P91 Butt Weld Tube Fittings are high-performance components designed for high-temperature and high-pressure piping systems. Manufactured from ASTM A335 P91 alloy steel, they contain chromium and molybdenum, providing exceptional strength, oxidation resistance, and creep resistance. These fittings, including elbows, tees, reducers, and caps, ensure secure and leak-proof connections in industries such as power plants, refineries, and petrochemical facilities. Their superior mechanical properties make them ideal for demanding applications requiring durability and thermal stability. Conforming to ASME and ASTM standards, P91 Butt Weld Tube Fittings guarantee long service life, reliability, and efficiency in critical piping systems.
