HY M400 Chemical composition

HY M400 Physical properties

HY M400 Alloy minimum mechanical properties in the room temperature

Characteristic as below:
HY M400 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.
HY M400 Metallurgical structure
HY M400 alloy is high-intensity single-phase solid solution.

HY M400 Corrosion resistance
HY M400 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: HY M400have corrosion resistance in less than 85% consistency of sulfuric acid. HY M400is an important material that resistant to hydrofluoric acid. Water corrosion: HY M400 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: HY M400 for the work of the highest temperature at about 600 ℃ in general in the air, in the high temperature steam, the corrosion rate less than 0.026mm / a. Ammonia: HY M400 can be resistant to an hydrous ammonia and aminate conditions corrosion below 585 ℃ due to the high nickel.
HY M400 Application field：
HY M400 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
