Audited Supplier Hastelloy X is one of the most widely used nickel-based alloys due to its high resistance to oxidation and high temperature strength. Also known as Alloy "X", is commonly used in gas turbine engine components, furnace applications and any type of combustion zone sections such as tailpipes, cabin heaters and heat-treating equipment. Its good resistance to stress-corrosion cracking and carburization make it suitable for petrochemical processing equipment and all types of forming and welding. Hastelloy alloy X is machinable in the rolled and cast form at low cutting speeds and coolant is required. All rolled forms of Hastelloy X are provided in the solution heat-treated condition. Standard practice heat-treatment is 2150°F followed by rapid cooling.
Hastelloy X is strong and resistant to oxidation. It is also extremely resistant to stress and corrosion cracking in petro chemical applications. Hastelloy X is easily fabricated and has great forming and welding characteristics. Hastelloy X can also be forged and due to its great ductility Hastelloy X can be cold worked.
Hastelloy X is available in pipe, plate, sheet, tubing, and round bar.
