Inconel 800 Parts

Overview of Inconel 800

Inconel 800 is an alloy that typically contains 15-25% Cr, 30-45% Ni, and small amounts of Al and Ti.

This alloy has a high chromium content and sufficient nickel content, so it has a high temperature corrosion resistance, and is widely used in industry.

Inconel 800 Part

It has excellent stress corrosion cracking resistance in chloride, low concentration NaOH aqueous solution and high temperature and high pressure water, so it is used to manufacture stress corrosion cracking resistant equipment.

For example, chemical industry nuclear generators, nitric acid coolers, acetic anhydride cracking tube heat exchange equipment, heat exchange tube, these devices all use Incoloy800 alloy.
