MONEL K-500 Description
MONEL K-500 alloy has the same corrosion resistance as 400, but has higher mechanical strength and hardness. It has good corrosion resistance and long-term structure stability.
It is mainly used to manufacture turbine blades and gas turbine blades whose working temperature is below 750℃ on aeroengines; Used for manufacturing fasteners and springs on ships; Pump and valve parts for chemical equipment; Pulp blades on paper making equipment, etc.
Product specification range:
Forgings, bars, dimensions can be zero cut, strip, ring, wire, flange and other products can be produced according to customer requirements.
Fitur | Monel K-500 (UNS N05500)MONEL K-500 alloy has the same corrosion resistance as 400, tetapi memiliki kekuatan mekanik dan kekerasan yang lebih tinggi. Ini memiliki ketahanan korosi yang baik dan stabilitas struktur jangka panjang. Hal ini terutama digunakan untuk memproduksi bilah turbin dan bilah turbin gas yang suhu kerjanya di bawah 750℃ pada mesin pesawat; Digunakan untuk pembuatan pengencang dan pegas di kapal; Bagian pompa dan katup untuk peralatan kimia; Pisau pulp pada peralatan pembuatan kertas, dll. | ||||||||
Ringkasan | Paduan nikel-tembaga yang dapat diperkeras dengan presipitasi yang menggabungkan ketahanan korosi paduan MONEL 400 dengan kekuatan dan kekerasan yang lebih besar. Ia juga memiliki permeabilitas rendah dan nonmagnetik pada suhu serendah -150°F (-101°C). Digunakan untuk poros pompa, perkakas dan instrumen sumur minyak, bilah dan pengikis dokter, pegas, trim katup, pengencang, dan poros baling-baling laut. | ||||||||

Struktur mikro | Monel K-500 yang diproduksi dengan menambahkan aluminium dan titanium ke komposisi dasar nikel-tembaga Monel juga memiliki struktur kubik berpusat muka. Dalam kondisi agehardened, terdapat fase gamma prime Ni3Al submikroskopis | ||||||||
karakter | Monel K-500 has excellent corrosion resistance in an extensive range of natural and chemical environments, excellent resistance to chloride-ion stress-corrosion cracking and very high strength and hardness. After age-hardening, Monel K-500 has approximately 2 to 3 times higher mechanical properties than the nickel-copper alloy (Monel 400), high tensile properties up to about 650 ℃, good corrosion fatigue resistance and ow permeability with non-magnetic down to -135 ℃. | ||||||||
Tahan korosi | In general, the corrosion resistance of Monel K500 is similar to that of Monel 400. Excellent resistance is shown to a wide range of media from pure water to mineral acids, salts and alkalis. | ||||||||
| Monel K-500 is virtually immune to chloride-ion stress-corrosion cracking. In the aged condition, the alloy may be susceptible to stress-corrosion cracking in moist, aerated hydrofluoric acid vapour at stresses near the yield strength. | |||||||||
| In high-velocity seawater and in marine atmospheres, good corrosion resistance is shown but, in slow-moving or stagnant seawater, pitting may occur. Nicorros Al also shows good resistance in sour-gas environments. | |||||||||
Aplikasi | |||||||||
| Monel K-500 finds wide application in the marine, chemical, petrochemical and shipbuilding industries. | |||||||||
| Typical applications include: | |||||||||
| 1. Valve seals, pump sleeves and wear rings in marine | |||||||||
| environments – high strength and resistance to seawater； | |||||||||
| 2. Fasteners, e.g. bolts, used in marine atmospheres and tidal waters – resistance to chloride-containing environments; | |||||||||
| 3. Doctor blades and scrapers; | |||||||||
| 4. Towing cable armouring – high strength, non-magnetic properties and resistance to seawater; | |||||||||
| 5. Oil well drilling equipment such as non-magnetic drill collars, valves and instrumentation sleeves – resistance to chloride-containing media and sour-gas environments; | |||||||||
| 6.Springs – resistance to a variety of corrosive media; | |||||||||
| 7.Aviation instrument components – non-magnetic properties. | |||||||||
