Hastelloy S/UNS N06635 Wire rod/Plate/Fittings

Hastelloy, also known as Hastelloy S, is a high-performance alloy developed by Haynes International in the United States. The alloy is a nickel-based alloy with excellent corrosion and high temperature resistance, which can be applied to a wide range of industrial fields. Compared with other alloys, it has higher strength and better corrosion and wear resistance, and can be used in some occasions where corrosion resistance and thermal stress resistance are particularly high. In many fields, especially in high-tech areas such as aviation, chemical, Marine and nuclear industries

Product Description:

Hastelloy S is a high-performance alloy with nickel, chromium, and molybdenum as its main elements. The higher proportion of molybdenum enhances its corrosion resistance and high-temperature capabilities. Additionally, the alloy incorporates other elements such as copper, iron, cobalt, tungsten, and carbon to improve its mechanical properties. With a broad range of applications, Hastelloy S is used in manufacturing aircraft engine components, petrochemical equipment, nuclear energy equipment, electronic appliances, and marine equipment. It withstands acidic, alkaline, high-temperature corrosive media, and oxidation atmospheres. In the nuclear industry, Hastelloy S demonstrates strong radiation resistance and is utilized in the production of nuclear reactor shells, reactor internal pipes, and nuclear fuel elements.
