Product details:

Monel 400(UNS N04400, NCu30) monel 400 alloy is a single phase solid solution with high strength. This alloy has excellent corrosion resistance in hydrofluoric acid and fluoric gas medium, as well as in hot concentrated alkali solution. It is also resistant to corrosion of neutral solution, water, seawater, atmosphere and organic compounds. An important characteristic of this alloy is that it does not produce stress corrosion crack and has good cutting performance.

Chemical composition:

Ni: allowance; Cu: 28-34; Si: < 0.5; Mn: < 2.0; C: < 0.30; Fe: < 2.0

Monel K500(UNS N05500)

Monel K500 alloy not only has excellent mechanical properties such as high strength, corrosion resistance and non-magnetism, but also has the same corrosion resistance as monel 400 alloy. Can be used as pump shaft material, suitable for bad high sulfur, high wax layer geology

Working under mining conditions. Since the alloy has no plastic-brittle transition temperature, it is very suitable for all kinds of cryogenic equipment. This alloy is mainly used for pump shaft and valve stem, conveyor scraper, oil well drilling ring, elastic parts, valve pad, etc. Applicable to the stone

Oil, chemical, shipbuilding, pharmacy, electronics.

The chemical composition of this alloy is roughly the same as that of monel 400, and the biggest difference is that it contains 2.3-3.15% A1 and 0.30-1.00% Ti. Besides the dispersed Ni3 (A1,Ti) precipitation phase, the microstructure of this alloy is other

Same as monel 400.

Ni: > 63; Cu: 27/33; Mn < 1.5; Fe < 2; Si < 0.5; A1 2.3/3.15; Ti0.35/0.85

Corrosion resistance:

The alloy has excellent corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives. At the same time, it has better corrosion resistance than copper base alloy in seawater.

▲ acid medium: M400 is corrosion resistant in the concentration of less than 85% sulfuric acid. M400 is one of the few important materials for durable hydrofluoric acid.

▲ water corrosion: under most water corrosion conditions, M400 alloy not only has excellent corrosion resistance, but also hole corrosion and stress corrosion are rarely found, and the corrosion rate is less than 0.25mm/a.

▲ high temperature corrosion: M400 in the air, the highest continuous working temperature is generally around 600℃, in high temperature steam, the corrosion speed is less than 0.026mm/a.

▲ ammonia: because monel 400 alloy nickel content is high, it can withstand the corrosion of anhydrous ammonia and ammonia under the condition of 585℃.
