67% nickel + 30% copper golden ratio: corrosion rate in hydrochloric acid, sulfuric acid, and hydrofluoric acid environments is only 1/12 that of 316 stainless steel (ASTM G48 standard test)
Salt spray test breaks limits: 5,000 hours with zero red rust on the surface (ISO 9227), 8 times longer lifespan than conventional stainless steel nuts
-200°C to 480°C full temperature range protection: no brittleness at liquid nitrogen temperatures, no loss of strength at boiler temperatures
Corrosive Medium Monel 400 Nut 304 Stainless Steel Nut
Seawater immersion (1 year) Weight loss <0.002 mm Pitting depth >0.8 mm
Hydrofluoric acid vapor (40°C) Surface intact Complete corrosion within 72 hours
Sulfide stress corrosion Immune Crack rate >90%
Dual-standard certification shield:
✅ ASTM B164 Grade Monel 400 (American Standard)
✅ GB/T 5235-2023 NiCu30Fe (National Standard)
Full Lifecycle Traceability: Laser-marked batch number + material identification, supporting third-party spectral re-inspection
Carbon-Neutral Process: Melting process carbon emissions reduced by 37% compared to traditional alloys (ISO 14064 certified)
⛟ Value formula: (Equipment lifespan × Safety factor) ÷ (Maintenance costs × Downtime risk) = Industrial investment return multiplier

Monel 400 Characteristic
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 ºC 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 ºC due to the high nickel.
Monel 400 Application field:
Monel 400 alloy is a multi-purpose material in many industrial applications:
● Seamless water pipe in the power factory
● Sea-water exchanger and evaporator
● Sulfuric acid and hydrochloric acid environment
● Crude distillation
● Sea-water in the use of equipment and propeller shaft
● Nuclear industry and used in the manufacture of enrichment isotope separation equipment
● Manufacturing hydrochloric acid equipment used in the production of pump and valve
