Monel 400 alloy high-strength single-phase solid solution, it is a largest amount of the most versatile, comprehensive performance excellent corrosion resistant alloys. This alloy has excellent corrosion resistance in the medium of hydrofluoric acid and fluorine gas, and also have excellent corrosion resistance in hot concentrated alkali. Also resistant to corrosion of the neutral solution, water, sea water, the atmosphere, the organic compound. An important feature of the alloy is generally does not produce stress corrosion cracking, and good cutting performance.

Corrosion Resistance

Extremely excellent corrosion resistance of the alloy in the fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives. More corrosion resistance than the copper-based alloys in seawater.

Acid medium: M400 in the sulfuric acid concentration is less than 85% of the corrosion.

The M400 is one of the very few important materials in hydrofluoric acid resistant.

Water corrosion: M400 alloy in most water corrosion cases, not only excellent corrosion resistance, and pitting corrosion, stress corrosion rarely found corrosion rate less than 0.025mm / a

High Temperature Corrosion: M400 continuous work of the highest temperature in the air at about 600 ℃, high temperature steam, the corrosion rate of less than 0.026 mm / a.

Ammonia: Monel 400 alloy nickel content is high, can withstand 585 ℃ anhydrous ammonia and corrosion ammoniation conditions.
