NXF UNS S33400/Incoloy 840/ASTM A240/ASME SA-240/NAS H840 DN15-1200 SCH10-XXS Butt Welding Straight/Reducing Cross Tee

An Incoloy 840 cross tee is a type of pipe fitting made from Incoloy 840, a high-performance, nickel-chromium-iron superalloy. The "cross tee" shape is used in piping systems to connect four pipes in a cross configuration, allowing for fluid or gas flow diversion and splitting. This specific fitting is designed for demanding environments involving high temperatures and corrosive media.

Key Characteristics of Incoloy 840Incoloy 840 (also known as Alloy 840, UNS S33400, or W.Nr. 1.4847) is primarily valued for its superior performance at elevated temperatures compared to standard stainless steels like 304 or even some other Incoloy grades. High-Temperature Resistance: It can withstand continuous service temperatures up to approximately 1000°C (1832°F).Oxidation and Corrosion Resistance: The alloy's composition, which includes chromium, nickel, titanium, and aluminum, promotes the formation of a stable, protective chromium oxide layer on its surface. This layer effectively resists oxidation, scaling, and general corrosion in harsh chemical and marine environments.Mechanical Strength: Incoloy 840 exhibits high mechanical strength and good resistance to thermal fatigue and creep, making it durable under thermal cycling and prolonged stress.Fabricability: It can be readily formed, machined, and welded using standard industrial techniques.
