Monel K500 vs Monel 400: Doorashada Alloy-ka Nikkel-Copper ee Saxda ah ee Codsiyada Waalka Baahida leh
Xulashada dahaarka Monel ee ugu fiican waa mid muhiim u ah waxqabadka iyo cimri dhererka jawiga adag sida injineernimada badda, saliidda iyo gaaska, iyo farsamaynta kiimikada. Iyadoo Monel 400 iyo Monel K500 labaduba ay yihiin dahaarka nickel-copper ee caanka ah oo bixiya iska caabin daxalka oo aad u fiican, halabuurka iyo sifooyinka kala duwan ee ay leeyihiin ayaa ka dhigaya kuwo ku habboon caqabadaha kala duwan. Doorashada khaldan waxay horseedi kartaa guuldarro degdeg ah ama kharash aan loo baahnayn. Tilmaamahan wuxuu bixiyaa isbarbardhig qoto dheer iyo talo xulasho wax ku ool ah oo loogu talagalay injineerada, iyadoo diiradda la saarayo codsiyada Monel Valve.
1. Kala duwanaanshaha Muhiimka ah: Halabuurka & Xoojinta
Halabuurka Kiimikada (Heerka ASTM)
| Walax | Monel 400 | Monel K500 |
|---|---|---|
| Nikkel (Ni) | 63-70% | 63-70% |
| Naxaas (Cu) | 28-34% | 27-33% |
| Aluminium (Al) | - | 2.3-3.15% |
| Titanium (Ti) | - | 0.35-0.85% |
| Bir (Fe) | ≤ 2.5% | ≤ 2.0% |
Waxyaabaha Muhiimka ah ee Laga Qaadan Karo:
Monel K500 waxa ku jira ku darid ula kac ah oo Aluminium (Al) iyo Titanium (Ti). Tani waxay suurtogal ka dhigaysaa in la adkeeyo da'da (da'itaanka marxaladda γ'), taasoo si weyn u xoojinaysa xooggeeda.
Monel 400 wuxuu ku tiirsan yahay oo keliya xoojinta xalka adag. Waxyaabaha uu ka kooban yahay naxaasta oo xoogaa ka sarreeya waxay xoojisaa iska caabbinta deegaannada aashitada ee gaarka ah ee yareeya.
Labaduba waxay ilaaliyaan matrix-ka Ni-Cu ee aasaasiga ah ee mas'uulka ka ah iska caabbinta daxalka ee aadka u fiican.

2.2 Iska caabbinta Daxalka
| Nooca Daxalka | Waxqabadka Monel 400 | Waxqabadka Monel K500 |
|---|---|---|
| Daxalka Biyaha Badda | Aad u fiican (la xaqiijiyay tobanaan sano) | Aad u Fiican (laakiin u nugul SCC meelaha ay ku badan tahay walbahaarka) |
| Deegaannada Aashitada leh (tusaale ahaan, Sulfuric, HF) | Sare (doorashada ugu fiican ee lagu yareeyo asiidhyada) | Wanaagsan (Ku darista Al/Ti waxay si yar u kordhisaa khatarta tuurista) |
| Oksaydheynta Heerkulka Sare | Xasilloon ilaa 480°C (900°F) | Xasilloon ilaa 540°C (1000°F) (Al waxay hagaajisaa iska caabbinta oksaydhka) |
| Jabinta Daxalka Cadaadiska (SCC) | Aad u Adkeysi Badan (Si dhif ah ayay u dhacdaa) | Waa mid u nugul (taxaddar ayaa loo baahan yahay marka ay jiraan jawi cadaadis sare leh + halogen) |
Fiiro gaar ah: Xalka 3.5% NaCl ee 50°C, heerka SCC ee Monel K500 wuxuu qiyaastii 30% ka hooseeyaa Monel 400's.

3.1 Samaynta
| Geedi socodka | Monel 400 | Monel K500 |
|---|---|---|
| Heerkulka oo la qaloocinayo | 870-1175°C (1600-2150°F) | 980-1200°C (1800-2200°F) (daaqad cidhiidhi ah) |
| Shaqeyn Kulul | Fudud | Waxay u baahan tahay xakameyn adag (heerkulka dhammaadka waa muhiim) |
| Alxanka | Aad u fiican (TIG, MIG, Dareerin) | Ka liita (waxay u baahan tahay gabowga ka dib alxanka si loo helo xoog buuxa) |
3.2 Daaweynta Kulaylka
