Sab saum toj contenders nyob rau hauv lub teb muaj xws li Alloy 400 thiab Hastelloy C, ob alloys dav lees paub rau lawv superior kev kawm nyob rau hauv hnyav ib puag ncig. Hauv tsab ntawv blog no, peb yuav ua tib zoo saib ntau yam ntawm qhov sib txawv ntawm ob lub alloys no los pab koj txiav txim siab xaiv rau koj daim ntawv thov tshwj xeeb.
hauj lwm:
Alloy 400, tseem hu ua Monel 400, yog nickel-tooj liab alloy uas nws muaj pes tsawg leeg muaj feem ntau ntawm npib tsib xee (63-70%) thiab tooj liab (20-29%). Tsis tas li ntawd, nws muaj me me ntawm hlau, manganese, carbon thiab silicon. Hastelloy C, ntawm qhov tod tes, yog ib tsev neeg hlau uas muaj feem ntau ntawm cov npib tsib xee, molybdenum, thiab chromium, nrog cov proportions sib txawv nyob ntawm cov qib tshwj xeeb (xws li Hastelloy C276). Qhov tshwj xeeb muaj pes tsawg leeg ntawm cov alloys no muab lub hauv paus rau lawv cov khoom sib txawv.
Corrosion kuj:
Alloy 400 thiab Hastelloy C ob leeg muaj kev tiv thaiv corrosion zoo heev, ua rau lawv zoo tagnrho rau cov ntawv thov hauv qhov chaw nruj thiab corrosive. Alloy 400 muaj kev tiv thaiv zoo rau ntau yam corrosive agents, xws li dej hiav txwv, acids thiab alkalis. Cov cuab yeej no ua rau nws xaiv thawj zaug rau kev siv dej hiav txwv thiab cov khoom siv raug dej ntsev. Hastelloy C, ntawm qhov tod tes, muaj cov ntsiab lus siab molybdenum thiab chromium thiab muaj kev tiv thaiv zoo rau ntau yam kev tawm tsam, suav nrog sulfuric acid, hydrochloric acid thiab chloride daws. Yog li ntawd, Hastelloy C feem ntau nyiam nyob rau hauv kev lag luam tshuaj thiab petrochemical industries uas raug rau cov tshuaj hnyav heev.
lub zog:
Hastelloy C feem ntau zoo dua rau Alloy 400 hais txog lub zog. Cov ntsiab lus molybdenum thiab chromium hauv Hastelloy C pab txhawb rau nws lub zog siab dua thiab cov khoom siv kho tshuab zoo heev, muab kev ua tau zoo ntawm qhov kub thiab txias. Hauv qhov sib piv, Alloy 400 tsis tshua muaj zog tshaj Hastelloy C tab sis khaws cov ductility zoo, ua rau nws haum rau qee yam kev siv uas xav tau kev tsim thiab yooj yim ntawm fabrication.
tus nqi:
Vim nws cov nickel thiab tooj liab muaj pes tsawg leeg, Alloy 400 yog tus nqi ntau dua li ntau qib ntawm Hastelloy C, uas muaj cov nickel, molybdenum thiab chromium ntau dua. Tus nqi sib txawv ntawm cov alloys no tuaj yeem yog qhov tseem ceeb thaum xaiv cov khoom tsim nyog rau ib qhov project tshwj xeeb, tshwj xeeb tshaj yog thaum txiav txim siab qhov ntsuas thiab kev txwv nyiaj txiag.
daim ntawv thov:
Kev xaiv ntawm Alloy 400 thiab Hastelloy C feem ntau yog nyob ntawm cov kev thov tshwj xeeb. Alloy 400 yog dav siv nyob rau hauv marine engineering, chemical khoom thiab aerospace industries vim nws zoo heev tsis kam mus seawater thiab ntau yam acids. Hastelloy C, ntawm qhov tod tes, yog qhov zoo dua rau cov ntawv thov uas muaj cov kua qaub muaj zog, ib puag ncig tshuaj lom neeg hnyav, thiab kub kub. Nws yog dav siv nyob rau hauv chemical processing, pollution control, oil and gas industries.
Lwm qhov sib txawv:
Ntxiv rau qhov sib txawv tseem ceeb uas tau hais los saum no, Alloy 400 yog sib nqus thaum Hastelloy C tsis yog hlau nplaum. Cov cuab yeej sib nqus no ntawm Alloy 400 tuaj yeem yog qhov tseem ceeb hauv qee qhov kev siv uas sib nqus cuam tshuam yog kev txhawj xeeb.
