Astec tubes have been the renowned manufacturer and supplier of a variety of steelworks. Hastelloy Pipe Fittings is one of them. Hastelloy pipes are nickel- molybdenum alloy. It comes in various grades and specifications. It is known for its modification qualities as per the requirements of clients. All the grades and specifications have a high resistance to corrosion. Hastelloy belongs to the superalloy family. Many of its grades have the composition of nickel, chromium, and molybdenum. Thus, they have excellent resistance to oxidation and corrosion. The addition of molybdenum contents makes it harder and stronger. It has a marvelous ability to perform in high temperatures. This alloy has great machinability, ductility, and weldability. Also, it can work well in forging and cold working.This alloy’s great resisting quality makes it the first choice for corrosive environments both moderate and severe. It has been widely used by the chemical processing industries. Also, Hastelloy’s reliable performance has made its place in the areas of geothermal, solar energy, oil and gas, and pharmaceutical. Mostly, Hastelloy material is used over the stainless steel in respect of corrosion resistance. Hence, it is also used in the power generation, specialty chemicals, seawater equipment, heat exchangers and condensers.
