Harsh Steel

Waspaloy Sheet


Waspaloy Sheet

Waspaloy Sheet that we export and supply is widely in demand amongst buyers. It is a wrought nickel base super alloy that is available as per AMS 5544, AMS 5708, AMS 5828, EN 2.4654 and also known as UNS N07001 with Werkstoff 2.4654 containing high amounts of chromium and cobalt. Our Waspaloy Sheet is extremely resistant to corrosion and oxidation. It is appreciated for its high creep rapture strength which is ideal to be installed in the hottest sections of jet engines where alloys such as Inconel 718 too fail. Waspaloy Sheet easily retains its strength even at very high temperature, which makes it ideal for making fighter jet components. It is used in the hottest applications such as blades of engines, rings, seals and fabricated components of aerospace and defense equipment. We provide Waspaloy Sheet and bars of different sizes.
