Lawg: A Hom Lub Npe(Guardemarked los ntawm Haynes Thoob Ntiaj Teb) rau ib tsev neeg ntawm Nickel-based superalloys tsim los tiv thaiv corrosion, siab kub, thiab muaj ib puag ncig tshuaj heev. Tsev neeg haastelloy suav nrog ntau yam kev tsim tawm, txhua qhov tsim rau cov ntawv thov tshwj xeeb. Piv txwv suav nrog Hastelloy C276, C22, B2, X, thiab G30, ntawm lwm tus.
Hauv ntej, "hastelloy" yog lub kaus lub kaus uas muaj ntau yam ntawm alloys, tsis yog ib qho khoom siv.
Alloy C276: A Tshwj Xeeb Alloynyob rau hauv tsev neeg haasteloy. Nws yog ib qho ntawm cov qib zoo tshaj plaws thiab dav siv Hastelloy cov qib (piv txwv li, acids, collorides, thiab oxidizing / txo cov xwm txheej).
Alloy C276 muaj qhov txhais tau cov tshuaj txhais tau tias, thaum "haastelloy" li ib tsev neeg suav nrog cov alloys nrog sib txawv nrog sib txawv.
Alloy C276Feem ntau muaj:
50-60% Nickel (NI, Base Eles)
15-18% chromium (CR, txhim kho oxidation tsis kam)
15-17% Molybdenum (mo, tiv thaiv pitting thiab crevice corrosion)
3-4% tungsten (w, txhawb zog thiab corrosion tsis kam)
Me me ntawm hlau (FE, ~ 5%), cobalt (CO,<2%), and trace elements (e.g., carbon, silicon).
Lwm cov Hastelloy alloysnyias muaj nyias kev sib txawv. Piv txwv li:
Hastelloy C22: Siab chromium siab (20-22%) thiab qis Molybdenum (12-14%) dua li C276, muab cov kua qaub oxidizing.
Hastelloy B2: High Nickel (65-70%) thiab Molybdenum (26-30%), optimized rau kev txo ib puag ncig zoo li hydrochloric acid.
Alloy C276yog kev ua kev zoo siab rau nws cov versatility:
Tiv thaiv ob qho tib si oxidizing (piv txwv li, nitric acid) thiab txo qis (piv txwv li, sulfuric acid).
Ua tau zoo hauv chloride ib puag ncig (piv txwv li, seawater, brines) yam tsis muaj pitting lossis kev ntxhov siab corrosion tawg.
Siv hauv kev ua tshuaj, roj thiab roj (cov khoom siv tawm tsam), tswj kev qias tuaj, thiab tshuaj siv qias neeg.
Lwm cov Hastelloy alloysPab nom tsoom nican:
Hastelloy C22: Nyiam nyob rau hauv high-oxidation scararios (piv txwv li, pulp thiab ntawv tshuaj dawb).
Hastelloy B2: Zoo tagnrho rau kev zwm zog hydrochloric acid thaum kub siab.
Hastelloy X: Tsim kom muaj kev kub siab (txog 1200 degree), siv rau hauv cov roj turbines thiab cub taws ua kom haum.
Cov tub ntxhais sib txawv yog hierarchical:Alloy C276 yog hom hastelloy, tab sis "haastelloy" yog hais txog tag nrho tsev neeg ntawm alloys hauv qab ntawd hom. Xav txog nws zoo li "Ford" (Hom / Tsev Neeg) tiv thaiv "Ford F-150" (ib tus qauv tshwj xeeb hauv lub hom).
"Hastelloy" yog lub npe nrov rau ib pawg ntawm cov neeg npib tsib xee-as -kas alloys, thaum alloy C276 yog cov pab pawg uas muaj cov muaj kev sib xyaw ua ke thiab cov khoom siv.
