25th floor, C3 Building, Wanda Plaza, Kaifu District, Changsha, Hunan Province, China.Monel 400 alloy is a corrosion-resistant alloy with the largest consumption, the most versatile and excellent comprehensive performance. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance to hot concentrated lye. At the same time, it is resistant to corrosion from neutral solutions, water, sea water, air, organic compounds, etc. High temperature and corrosion resistant alloy, widely used in sea water and other fields. An important feature of this alloy is that it generally does not produce stress corrosion cracks and has good cutting performance.
Monel 400 alloy has excellent corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives. At the same time, it is more corrosion resistant than copper-based alloys in seawater. Acid medium: Monel 400 is corrosion resistant in sulfuric acid with a concentration of less than 85%. Monel 400 is one of the few important materials that can withstand hydrofluoric acid. Water corrosion: Under most water corrosion conditions, Monel 400 alloy not only has excellent corrosion resistance, but also pitting corrosion and stress corrosion are rarely found, and the corrosion rate is less than 0.025mm/a. High-temperature corrosion: The maximum temperature of Monel 400 continuous working in air is generally around 600℃, and the corrosion rate in high-temperature steam is less than 0.026mm/a. Ammonia: Due to the high nickel content of Monel 400 alloy, it can withstand corrosion under anhydrous ammonia and ammoniating conditions below 585℃.
Monel 400 alloy is a nickel-based corrosion-resistant alloy that has been used in industry for a long time. It has good comprehensive properties and a wide range of applications. It has become an indispensable alloy due to its good corrosion resistance. Its chemical composition is mainly composed of Ni, 30% Cu and added It is composed of a small amount of Fe (1%-2%).
Monel K500 actually has the same corrosion resistance as Monel 400, but compared to 400, it has higher mechanical strength and hardness. It also has better heat-resistant corrosion resistance and long-term structural stability. But the plasticity is slightly lower than that. Compared with Monel 400, Monel K500 contains 2.3%~3.15% aluminum AL and 0.3%~1.00% titanium Ti.
Monel K500 alloy is mostly used the same as 400, but if there is an alloy other than 400 that is not applicable, Monel K500 alloy is mainly used for pump shafts, impellers, conveyor scrapers, oil drill rings, strong parts, valve parts, and papermaking equipment. Squeegee blades, etc.
Monel K500 alloy has excellent corrosion resistance, and at the same time has higher strength and hardness than Monel 400. This is due to the addition of Al, Ti and other elements to the alloy, after a certain heat treatment, there are dispersed intermetallic compounds on the matrix. The structure is single-phase austenite structure and precipitated by dispersed Ni3 (Al, Ti) precipitation phase.
Monel K500 has approximately three times the yield strength of Monel 400 and twice the tensile strength. Higher mechanical properties can be obtained through cold working or age hardening. Monel K500 alloy has the same corrosion resistance as Monel 400 alloy.
Monel K500 alloy is mainly used for pump shafts and impellers, conveyor scrapers, oil well drilling rings, elastic parts, valve pads, etc. Others can also manufacture various heat exchange equipment, boiler feedwater heaters, petroleum and chemical pipelines, containers, towers, tanks, valves, pumps, reactors, shafts, etc. Due to the low corrosion rate in flowing seawater and the high strength of this alloy, Monel K500 is suitable for manufacturing seawater-resistant centrifugal pump shafts. It is suitable for static and flow rate sea water.
Monel K500 has the same corrosion resistance as Monel 400, but has higher mechanical strength and hardness. It has good thermal corrosion resistance and long-term structural stability. Mainly used to manufacture turbine blades and gas turbine blades on aero engines whose working temperature is below 750℃; used to manufacture fasteners and springs on ships; pump and valve parts on chemical equipment; scraper blades on papermaking equipment Wait.
