Simbi isingatsvigiri 304 ine 18–20% chromium, 8–10.5% nickel, uye isingasviki 2% manganese. Simbi isingatsvigiri 201 ine 16–18% chromium, 3.5–5.5% nickel, uye 5–7.5% manganese yakakwira. Nitrogen yakakwira muna 201 (kusvika 0.25%) zvichienzaniswa ne304 (kusvika 0.10%). Nickel yakakwira muna 304 inoita kuti isatsvigiri ngura zvakanyanya uye chimiro chakasimba che austenitic. Kuwedzera kwe manganese ne nitrogen muna 201 kunotsiva simba asi kunoderedza kusatsvigiri ngura zvichienzaniswa ne304.
Simbi Isina Kusimba 304 vs 201

Mhedzisiro yeAlloy Elements paZvinhu zveMatombo
Kuwanda kwe nickel mu304 kunoita kuti ngura isanyanya kusimba, kunyanya kana paine acidic kana chloride, uye inokwanisa kunyungudika zvakanyanya. Chromium yakawanda inoumba passive oxide layer, ichidzivirira 304 kubva mukuoxidation. Muna 201, manganese ne nitrogen zvinorwisa kudzikira kwe nickel, zvichideredza mutengo asiwo zvichikonzera ngura dziri pakati nepakati, kunyanya munzvimbo dzine hunyoro kana munyu. 304 inowana simba rekudhonza rinosvika 520 MPa, inoburitsa simba rinosvika 215 MPa, uye inoreba kusvika 50%. 201 ine goho rakakwirira (275 MPa), inodhonza (kusvika 535 MPa), asi inoreba zvishoma (~45%), zvichikonzera kuputsika kwakanyanya.
Kuenzanisa Kwekushanda Kwemakanika
Kukohwa kwakanyanya kwe201 uye simba rekusimba rinoita kuti zvikamu zvakamanikidzwa kana kuti zvinotonhora zvigare kwenguva refu, asi kureba kushoma kunoderedza kusimba kwekutambanudza kwakadzika; matombo anogona kutsemuka pamakona akaomarara. Kukohwa kwakaderera kwe304 asi kusimba kwakanyanya kunotsigira kuumbwa kwakaomarara, kuchinjika kwakasimba, uye kupedzisa kwepamusoro kwakanatswa.
Kuramba Kuorauye Kukodzera Kushandisa
Kuramba Kuora Munzvimbo Dzakasiyana-siyana
Simbi isina ngura 304 inokunda 201 mukudzivirira ngura nekuda kwehuwandu hwayo hwakawanda hwe nickel ne chromium—8–10.5% Ni uye 18–20% Cr zvichienzaniswa ne3.5–5.5% Ni uye 16–18% Cr muna 201. Mukuyedzwa kwemunyu, 201 yakava nengura yebrown mukati memaawa makumi maviri nemana, nepo 304 isina kuratidza shanduko huru, kunyangwe mushure memaawa makumi manomwe nemaviri, zvichiratidza kukodzera kwayo chikafu, kurapa, uye nzvimbo dzemugungwa. Simbi isina ngura 201 inodzivirira ngura mumamiriro ekunze asina hunyoro, emukati asi inokundikana nekukurumidza munzvimbo dzine acidic, saline, kana hunyoro.
Mashandisirwo Akajairika uye Zvinodiwa Pakuita
304 inonyanya kushandisa mashandisirwo anoda kugara kwenguva refu uye hutsanana: michina yekubikira yekutengeserana, masinki, michina yekudya, uye zvishandiso zvekurapa (304 inodzivirira kusvibiswa uye inochengetedza kupenya). 201 inoona kushandiswa kwezvinhu zvevatengi, mapaneru ekushongedza, dzimba dzemidziyo, uye zvivakwa zvemukati uko zvinodiwa zvemakanika zviri pakati nepakati uye kusangana nezvinhu zvinoparadza kuri kushoma.
Njodzi dzekusazivikanwa zvisirizvo mukugadzira nekutengesa zvinhu
Kusarudzwa kwesimbi isina ngura kusina kunaka kunotungamira mukukundikana kwechigadzirwa nekukurumidza. Kuwanda kwe nickel ne chromium muGiredhi 304 kunoita kuti pave nekusagadzikana kwengura uye kuvimbika kwemuchina. Kana 201 ikatsiviwa ne304, kunyanya mukushandiswa kwechikafu, kwekurapa, kana kwemugungwa, ngura, gomba, uye kuora kwechimiro kunoitika. Zvikumbiro zvewarandi uye zvirango zvekutevedzera mitemo zvinobva mukutsiviwa, zvichikanganisa vagadziri nevatengesi. Simbi dzenhema uye dzakanyorwa zvisirizvo zvakajairika muzvitoro zvinofamba nekukurumidza, zvichiita kuti pave nekudiwa kukuru kwekusimbisa alloy isingaparadze uye chaiyo.
Nzira dzeKuziva Dzinowanzoitwa
Kuzivikanwa nemaoko kunoenderana nemhinduro yemagineti uye kuyedzwa kwemapoinzi emakemikari. Giredhi 304, ine nickel yakawanda, haina magineti akawanda pane 201. Zvisinei, kutonhora kana residual magnetism kunoita kuti nzira iyi isavimbike. Kuyedzwa kwekudonha kweasidhi kunoratidza kuvapo kwechromium, asi kududzirwa kwemhedzisiro hakusi kwemunhu uye hakuenderani. Nzira dzese dziri mbiri dzinokundikana kusiyanisa zvinhu zve alloy nehuwandu kana kuvimbisa kururama kana kuumbwa kwe alloy kuri pedyo kana pamusoro pakasvibiswa.
Mhinduro Yepamusoro: XRF Material Analyzer yekusimbisa Simbi Isina Kusimba
Mashandiro anoita XRF Alloy Analyzer
X-ray fluorescence (XRF) inoburitsa maX-ray ekutanga pasampuli yesimbi isina tsvina yakasimba, zvichiita kuti zvinhu zve alloy zvisvinure pa peaks yesimba re element-specific. Iyo analyzer inotora zviratidzo izvi uye ipapo ipapo inoona huwandu hwezvinhu zvakakosha zve alloy, zvinosanganisira chromium, nickel, manganese, nitrogen, uye iron. Kuongorora kwakazara kunoda zvishoma kupfuura30 masekondi pamuenzaniso wega wega, hazviparadzi zvachose, uye hazvichinje chimiro chemuviri kana pamusoro pechinhu chekuyedza.
Zvinhu uye Mabhenefiti of Lonnmeter XRF Alloy Analyzer
Dhizaini yemuchina uyu inofambiswa nebhatiri uye inotakurika inoita kuti ushande zvakanaka mumunda uye mukati memuchina. Chishandiso chayo che touchscreen chinotsigira kushanda nekukurumidza uye mishumo yakagadzirirwa uye inodhindwa. Kuongorora kunoitwa zvakananga pazvinhu zvakasimba, zvichiita kuti kuongororwa kurambe kuripo uye kunoshanda zvakanyanya. Kururama kwekuona kweLonnmeter (<±0.2% yezvinhu zvakakosha) inoshanda kupfuura nzira dzechinyakare dzakadai sekuongorora magineti uye bvunzo dzemapoinzi, izvo zvinowanzo kanganisa magiredhi kana mazinga emamanganese kana nitrogen akasiyana.
Kukosha Kwevashandisi Venyanzvi
Kuongororwa kwezvikamu zvakasiyana-siyana uye mishumo yekukurumidza kunoderedza nguva dzekuongorora neanopfuura 60%. Kuchengeta zvinyorwa zvedhijitari nekutevera mienzaniso yakasiyana kunovandudza kuteverwa kweongororo uye kutevedzera mitemo yemutengesi. Kuzivikanwa kwe alloy nguva dzose kunodzivirira kusawirirana kwewarandi uye kutadza kushanda zvakanaka.
Kumbira Mutengo uye Kubvunza Nyanzvi
Bata kuti uwane muenzaniso wakagadzirirwa uye kuongororwa kwehunyanzvi kweLonnmeter XRF Alloy Analyzer.
Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)
Zvinhu zve alloy zvinokanganisa sei mashandiro esimbi isina ngura?
Nickel yakawanda mu304 inosimbisa chimiro che microstructure, ichivandudza kuumbwa, ductility, uye kuramba makemikari ane simba. Muna 201, manganese nenitrogen zvakawedzera zvinotsiva nickel zvishoma, zvichiwedzera simba nekuoma asi zvichideredza kuramba ngura. Chromium yakawanda pamusoro pe18% inowedzera kugadzikana kwe304 pakuoxidation, ichiisiyanisa ne201 kuti ishandiswe zvakanyanya.
Ndezvipi zvikumbiro zvinonyanya kubatsira pakuzivikanwa kwemagiredhi nemazvo?
Zvikamu zvekuvaka, zvekushandisa zvekudya, zvekushandisa pakurapa, uye zvekugadzira zvinoda kuongororwa kwemagiredhi akavimbika kuitira kuti zvive nechokwadi chekuti zvinotevedzwa, kudzivirira magwaro ewaranti, uye kuvimbisa kuchengetedzeka kwekushandiswa kwekupedzisira. Kusarudzwa kwemagiredhi nemazvo kunovandudza mutengo wehupenyu hwese, kunyanya munzvimbo dzinokanganiswa nengura kana hutsanana.
