Monel 400 Application field
Monel 400 alloy is a multi-purpose material in many industrial
applications:
1. Seamless water pipe in the power factory
2. Sea-water exchanger and evaporator
3. Sulfuric acid and hydrochloric acid environment
4. Crude distillation
5. Sea-water in the use of equipment and propeller shaft
6. Nuclear industry and used in the manufacture of uranium
enrichment isotope separation equipment
7. Manufacturing hydrochloric acid equipment used in the production
of pump and valve
Characteristic as below
Monel 400 is an extremely combination property that use for largest
amount and most widely corrosion resistance alloy. This alloy in
the hydrofluoric acid and fluoride gas medium with excellent
corrosion resistance, as well as to the hot concentrated alkali. At
the same time, is also corrosion resistant to neutral solution, sea
water, air, organic compounds. An important feature of this is
generally do not generate a stress corrosion cracking, good cutting
performance.
Monel 400 Metallurgical structure
Monel 400 alloy is high-intensity single-phase solid solution.
Monel 400 Corrosion resistance
Monel 400 alloy in the fluoride gas, hydrochloric acid, sulfuric
acid, hydrofluoric acid and their derivatives have a very good
corrosion resistance property, and possess better corrosion
resistance more than the copper alloy in the sea water. Acid
medium: Monel 400 have corrosion resistance in less than 85%
consistency of sulfuric acid. Monel 400 is an important material
that resistant to hydrofluoric acid. Water corrosion: Monel 400
alloy in most corrosion cases of water, not only excellent
corrosion resistance, but also less pitting, stress corrosion, the
corrosion rate less than 0.025mm / a. High temperature corrosion:
Monel 400 for the work of the highest temperature at about 600 °C
in general in the air, in the high temperature steam, the corrosion
rate less than 0.026mm / a. Ammonia: Monel 400 can be resistant to
an hydrous ammonia and aminate conditions corrosion below 585 °C
due to the high nickel.
