Forging Hastelloy
Material Description
Hastelloy is a family of high-performance nickel-based alloys that are widely used in forging applications, particularly in industries where resistance to corrosion and extreme temperatures is essential. These alloys are known for their remarkable material properties, making them a preferred choice for critical applications. Hastelloy alloys typically contain a combination of nickel, chromium, molybdenum, and other elements, which contribute to their outstanding characteristics.
Hastelloy alloys are renowned for their exceptional corrosion resistance. They can withstand aggressive chemical environments, including acids, alkaline solutions, and saltwater. This property is especially valuable in industries like chemical processing, where equipment is exposed to harsh substances. Additionally, Hastelloy exhibits excellent high-temperature strength and oxidation resistance, making it suitable for applications involving extreme heat and pressure. Its exceptional mechanical properties, such as high tensile strength, ductility, and toughness, are highly advantageous for forging processes, ensuring the alloys maintain their structural integrity even under heavy loads.
Industry Applications
Critical for chemical resistance in defense, harsh environments in solar, handling equipment in medical, processing in EVs, chemical resistance in drones, processing components in aerospace, and chemical equipment in general engineering.
