This alloy has the following features:

Monel400 is an amount of the largest and most versatile, excellent overall performance of corrosion resistant alloys. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, hot concentrated alkali is also excellent in corrosion resistance. Also resistant to neutral solution, water, sea water, air, organic compounds corrosion. An important feature of the alloy is generally not produce stress corrosion cracking, good cutting performance.

Monel 400 Metallurgical structure:

Organization Monel400 alloy single-phase solid solution for high strength.

Monel 400 corrosion resistance:

Monel400 alloy has very good corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives in. Meanwhile in seawater corrosion resistance more than the copper-based alloys. Acid medium: Monel400 in sulfuric acid concentration is less than 85% of the corrosion resistance. Monel400 is one of the important material is resistant to hydrofluoric acid in very few. Water erosion: Monel400 alloy corrosion in most cases the water is not only excellent corrosion resistance and pitting corrosion, stress corrosion, also rarely found, the corrosion rate of less than 0.025mm / a. Temperature Corrosion: Monel400 continuous maximum temperature in the air is generally about 600 ℃, high temperature steam, the corrosion rate of less than 0.026mm / a. Ammonia: Monel400 due to the high nickel content alloys, it can be less resistant to corrosion under 585 ℃ anhydrous ammonia and ammoniated conditions.

 

This alloy has the following features:

Monelk500 known as UNS N05500, has monel400 same corrosion resistance, but has a higher mechanical strength and hardness. Has good corrosion resistance and long-term organizational stability. Mainly used in the manufacture of aviation on the operating temperature of the engine turbine blades and turbine blades below 750 ℃; the ship used in the manufacture of fasteners, springs; Whey scratch on papermaking equipment; pumps, valves, chemical equipment parts on blades, etc.
