Incoloy800 application field

chemical industry

Nuclear generator

Nitric acid cooler and acetic anhydride cracking tube

Heat exchange equipment

Cr content in 800 alloy is usually 15-25%, Ni content is 30-45%, and a small amount of Al and Ti is contained.

800 alloy is in a single austenite region after high temperature and rapid cooling, so the service state is a single austenite structure.

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

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 resistance equipment.

After rapid cooling at high temperature, the alloy is in a single austenite region, so the service state is a single austenite structure.

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

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 resistance equipment.

Has the following characteristics:

1. has excellent corrosion resistance in ultra-high temperature water medium up to 500℃

2. Good stress corrosion resistance.

3. Good processability
