Sei 904L iri Superior Grade kupfuura mamwe Stainless Steel Grades?

Simbi isina ngura yave chimwe chezvinhu zvinoshandiswa zvakanyanya mumaindasitiri nekuda kwekudzivirira kwayo ngura, kugara kwenguva refu, uye kushanduka-shanduka. Zvisinei, haasi ese magiredhi esimbi isina ngura akaenzana. Kunyange zvazvo magiredhi akadai se304, 316L, uye 317L achishandiswa zvakanyanya mumaindasitiri nemabhizimisi, pane rimwe giredhi rinomira pamusoro pemamwe maererano nekushanda kwayo:904L simbi isina ngura.

Inozivikanwa nehuwandu hwayo hwakawanda hwe nickel ne molybdenum, 904L isimbi isina ngura yepamusoro-soro yakagadzirirwa kubata mamiriro akaomarara. Muchinyorwa chino, tichaongorora kuti nei 904L ichionekwa seyakanakisa kupfuura mamwe marudzi esimbi isina ngura, tichitarisa pakuumbwa kwayo, hunhu hwemakanika, kuramba ngura, uye mashandisirwo ayo mumaindasitiri.

Kuumbwa kweSimbi Isina Kugadzika ye904L

Hunhu hwakanaka hwe904L hunobva mukuumbwa kwayo kwakasiyana kwemakemikari. Ine:

  • Nickel (Ni):24 - 26%

  • Chromium (Cr):19 - 23%

  • Molybdenum (Mo):4 - 5%

  • Mhangura (Cu):1 - 2%

  • Kabhoni (C):≤ 0.02%

  • Simbi (Fe):Kuenzana

Zvichienzaniswa ne316L (ine 10–14% nickel uye 2–3% molybdenum), 904L ine huwandu hwakawanda hwe alloying, zvichiita kuti irambe yakasimba zvakanyanya kumamiriro ekunze anoparadza.

Kuramba Kukuru Kwengura

1. Kuramba Kuora Kunokonzerwa neChloride

Nzvimbo dzine chloride yakawanda dzakadai semvura yegungwa kana saline solutions dzinorwisa zvakanyanya simbi dzisina ngura. Kunyange hazvo 316L ichigona kuramba kurwiswa nechloride kusvika pamwero wakati, inogona kukuvadzwa negomba uye kuputika. 904L, ine nickel nemolybdenum yakakwira, inopa dziviriro iri nani kubva mukuora kunokonzerwa nechloride.

2. Kuramba Simba reAcids

904L inodzivirira zvikuru maasidhi ane oxidizing akasimba akadai sesulfuric acid nephosphoric acid, nzvimbo dzine magiredhi akaita se304 ne316L anowanzo kundikana. Kuwedzerwa kwemhangura kunowedzerawo kudzivirira kwayo kuderedza maasidhi.

3. Kuramba Kuora Nekumanikidzwa

Kupwanya ngura yestress inzira inowanzo shandiswa pakubvisa simbi dzisina ngura kana dzichishandiswa zvisina simba munzvimbo dzine chloride. 904L inoratidza kusimba kunoshamisa kana tichienzanisa neasina simba, zvichiita kuti ive yakavimbika mukushandiswa kwakakosha.

Zvimiro zveMichina zve904L

  • Simba reKusimba:490 – 710 MPa

  • Simba reGoho (0.2% kuderedzwa):220 MPa

  • Kureba:35% zvishoma

  • Kuoma:≤ 90 HRB

Kunyange hazvo simba remuchina re904L rakafanana nemamwe marudzi e austenitic, kuramba kwayo ngura uye kusimba kwayo, kunyangwe patembiricha yakaderera, ndiko kunoita kuti ive yakasiyana.

Kuchinjika uye Kugadzira

Kufanana nedzimwe simbi dzisina ngura dzinoshandiswa neaustenitic, 904L inogona kusungirirwa zvakanaka uye inogona kugadzirwa mumhando dzakasiyana-siyana dzakadai semachira, maplate, mapaipi, uye zvigadziko. Kabhoni shoma inodzivirira kunaya kwemvura panguva yekusungirirwa, zvichiita kuti irambe ichidzivirira ngura munzvimbo ine kupisa.

Kuenzanisa nedzimwe Stainless Steel Grades

904L vs 304

  • 304 inoshandiswa zvakanyanya nekuda kwemutengo wayo wakaderera uye kuramba kwayo ngura zvakanaka.

  • Zvisinei, munzvimbo dzine chloride yakawanda kana kuti acidic, 304 inokundikana nekukurumidza, nepo 904L ichiramba yakagadzikana.

904L vs 316L

  • 316L inodzivirira ngura zviri nani pane 304 nekuda kwekuwedzera kwemolybdenum.

  • 904L inoshanda zvakanyanya kupfuura 316L mukudzivirira kupwanyika kwemakomba, ngura yakatsemuka, uye ngura ine simba.

904L vs 317L

  • 317L ine molybdenum yakawanda kupfuura 316L, zvichiita kuti irambe ichidzivirira ngura.

  • 904L, ine nickel nemhangura yakawanda, ichiri kupa kushanda kwakanaka mukuderedza acids nenzvimbo dzine hukasha dzechloride.

Simbi Dzisina Simba Dzinoputika 904L vs Duplex

  • Simbi mbiri dzakadai se2205 dzinopa simba rakawanda uye dzinodzivirira ngura zvakanaka.

  • Zvisinei, 904L inopa simba riri nani ku sulfuric acid uye ine simba risingatarisirwi munzvimbo dzakaoma dzemakemikari.

Mashandisirwo eindasitiri e904L

Nekuda kwekudzivirira kwayo ngura kusingaenzaniswi, 904L inoshandiswa mune mamwe maindasitiri anonyanya kuda zvinhu:

  • Kugadziriswa kweMakemikoro:Zvinoita kuti zvinhu zvisashande zvakanaka, zvinochinja-chinja kupisa, uye matangi anobata sulfuric nephosphoric acids.

  • Oiri neGasi:Nzvimbo dzegungwa, michina yepasi pegungwa, uye mapaipi ari mumvura yegungwa.

  • Indasitiri yeMarine:Kuvaka ngarava, nzvimbo dzinobvisa munyu, uye masisitimu ekutonhodza mvura yegungwa.

  • Kugadzirwa Kwemishonga Nezvekudya:Midziyo inoda hutsanana uye inoramba kushandiswa nezvinhu zvinochenesa.

  • Pulp nePepa:Zvishandiso zvekugaya chikafu nemidziyo yekupukuta.

Mabhenefiti eSimbi Isina Zvimbi ye904L

  1. Kuramba kwakanyanya kupesana nekuora kwegomba uye kukuvara kwemupata.

  2. Hupenyu hurefu hwebasa munzvimbo dzine hukasha.

  3. Inochengetedza ngura mushure mekunamira nekuda kwehuwandu hushoma hwekabhoni.

  4. Kushanda kwepamusoro-soro munzvimbo dzinokonzera oxidizing nekuderedza.

  5. Zvinhu zvakavimbika zvemaindasitiri uko kukundikana kusiri sarudzo.

Zvakaipa zveSimbi Isina Kushanda ye904L

  1. Mutengo Wakakwira:Kuwanda kwe nickel ne molybdenum kunoita kuti 904L idhure kupfuura 304 kana 316L.

  2. Kuwanikwa:Hazvina kuwanda semagiredhi akajairwa.

  3. Kugona kushandiswa:Zvinonetsa zvishoma kumuchina zvichienzaniswa nesimbi dzisina kusimba dzakasanganiswa nesimbi dzakaderera.

Pasinei nematambudziko aya, mabhenefiti ekushanda anowanzo pfuura matambudziko, kunyanya mumaindasitiri akakosha.

Nei 904L iri Giredhi Repamusoro

Kubudirira kwesimbi isina ngura ye904L kunobva mukuenzana kwayo kwakasiyana kwezvinhu:

  • Yakawanda nickel uye molybdenumkupa simba rekudzivirira mamiriro ezvinhu akaoma apo mamwe magiredhi anokundikana.

  • Kabhoni shomainodzivirira ngura pakati pegranular.

  • Kusimba kwakanyanyainovimbisa kushanda kwakavimbika mumabasa anoda simba.

  • Kuchinja-chinjainobvumira kushandiswa mumaindasitiri akasiyana-siyana kubva kumafekitori emakemikari kusvika kumainjiniya egungwa.

Kune maindasitiri anoda kuvimbika uye kugara kwenguva refu, 904L ndiyo sarudzo inosarudzwa pane magiredhi akajairwa akadai se304, 316L, uye kunyange 317L.

Basa reVatengesi Vakavimbika

Kunyange zvazvo 904L ichipa mashandiro akanaka kwazvo, mabhenefiti ayo anogona kuwanikwa chete kana ikawanikwa kubva kune vatengesi vane magwaro anoenderana nezvinodiwa zvepasi rose.sakysteelinopa simbi isina ngura ye904L yepamusoro-soro mumhando dzakasiyana-siyana, zvichiita kuti ive nechokwadi chekuti inoshanda zvakanaka uye yakavimbika. Nekusarudza, shandisa simbi yacho zvakanaka.sakysteel, maindasitiri anowana mukana wezvinhu zvakaedzwa, zvakanyoreswa, uye zvakagadzirira kushandiswa muzvishandiso zvinonyanya kuomera.

Mhedziso

Simbi isingatsvinyike ye904L inopfuura dzimwe simbi dzisingatsvinyike nekuda kwekusagadzikana kwayo nengura, kugona kwayo kubata maasidhi akasimba, uye kugara kwenguva refu munzvimbo dzine chloride. Kunyange zvazvo ichigona kudhura zvakanyanya, kugara kwayo kwenguva refu uye kugadziriswa kwayo kushoma kunoita kuti ive sarudzo inodhura zvishoma kune maindasitiri anoda kuvimbika uye kuchengetedzeka.

Kune mainjiniya, vagadziri, nevatengi, kunzwisisa kuti nei 904L iri nani kunoita kuti zvinhu zvakakodzera zvisarudzwe kumapurojekiti akakosha. Kushanda kwayo kwakasimbiswa kunoita kuti ive giredhi repamusoro resimbi isingatsvi iyo inoramba ichiisa mwero mumaindasitiri anodiwa zvakanyanya pasi rese.
