Description
Hastelloy C276 Bar (UNS N10276) is a highly versatile nickel-chromium-molybdenum alloy known for its exceptional resistance to a wide range of corrosive environments, including strong acids, chlorides, and seawater. With its outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking, it is widely used in industries such as chemical processing, power generation, and pollution control.
This alloy maintains its mechanical properties even at elevated temperatures, with a tensile strength of approximately 880 MPa and good weldability. It is available in various forms, such as cold-drawn, hot-rolled, and forged bars, and can be further processed to meet specific requirements. Compared to other corrosion-resistant alloys like Inconel 625, Hastelloy C276 offers superior resistance to a broader spectrum of chemicals, making it the preferred choice for critical applications in harsh industrial environments.
