Chitsulo Chosapanga Dzimbiri cha 304 vs 316: Momwe Mungasankhire Mipiringidzo, Mapepala ndi Machubu

Chiyambi

PoyerekezaChitsulo chosapanga dzimbiri cha 304 vs 316, ogula ayenera kusankha 304 pa nyumba zonse zamkati, zida za chakudya, zida zokongoletsera, zitsulo zosapanga dzimbiri, mapepala ndi machubu komwe dzimbiri ndi lochepa ndipo kuwongolera mtengo ndikofunikira. Sankhani 316 pamene kugwiritsa ntchito kumakhudza chloride, madzi a m'nyanja, malo okhala m'mphepete mwa nyanja, mankhwala, zida za m'nyanja, zida zachipatala, zigawo za mafuta ndi gasi kapena zofunikira zolimbana ndi dzimbiri. Kusiyana kwakukulu kwaukadaulo ndikuti 316 ili ndi molybdenum, yomwe imalimbitsa kukana kwa dzimbiri ndi dzenje, makamaka m'malo okhala ndi chloride.

Zonse ziwiri 304 ndi 316 ndi zitsulo zosapanga dzimbiri zogwiritsidwa ntchito kwambiri m'mipiringidzo, mapepala, mbale, mapaipi, machubu, waya, ma flange ndi zolumikizira. Zimapereka mawonekedwe abwino, kusinthasintha, ukhondo komanso njira zomaliza pamwamba. Komabe, kusankha mtundu wolakwika kungayambitse ndalama zosafunikira, dzimbiri msanga, kuchedwa kutumiza kapena kukana panthawi yowunikira polojekiti.

Pa kugula mafakitale, chisankho choyenera chiyenera kuganizira malo omwe zinthu zimawonongeka, zofunikira pamakina, kutentha, njira yopangira, kumaliza pamwamba, satifiketi, miyezo yomwe ilipo, kuwongolera kuchuluka kwa kutentha, EN 10204 3.1 MTC, kuyesa kwa PMI, kuyesa kwa UT, kuyang'anira kwa anthu ena, kulongedza kunja ndi kuthekera kotumizira.

Kodi 304 ndi 316 Zitsulo Zosapanga Dzira N'chiyani?

Chitsulo chosapanga dzimbiri cha 304 ndi chimodzi mwa zitsulo zosapanga dzimbiri za chromium-nickel austenitic zomwe zimagwiritsidwa ntchito kwambiri. Chimasankhidwa kwambiri pa zipangizo za kukhitchini, makina okonzera chakudya, zokongoletsera zomangamanga, zida zamafakitale, mapepala osapanga dzimbiri, machubu ndi mipiringidzo. Chimapereka kukana dzimbiri bwino m'malo abwinobwino komanso owononga pang'ono.

Chitsulo chosapanga dzimbiri cha 316 ndi chitsulo chosapanga dzimbiri cha austenitic, koma chili ndi molybdenum. Izi zimathandiza kukana dzimbiri la chloride, dzimbiri lozungulira komanso dzimbiri la m'ming'alu. Pa ntchito zapamadzi, zamankhwala, za m'mphepete mwa nyanja, zamankhwala, zamankhwala komanso zamafakitale zovuta, 316 nthawi zambiri imakondedwa kuposa 304.

Mafunso Ofunsidwa Kawirikawiri Zokhudza Chitsulo Chosapanga Dzimbiri cha 304 vs 316

1. Ndi chiti chabwino kuposa ichi, chitsulo chosapanga dzimbiri cha 304 kapena 316?

316 ndi yabwino kwambiri pa malo okhala ndi chloride, nyanja, gombe ndi mankhwala chifukwa ili ndi molybdenum. 304 ndi yabwino kwambiri ngati malo okhala ndi zinthu zambiri, mkati kapena akuwononga pang'ono ndipo wogula akufuna kuwongolera bwino mtengo. Kuchuluka kwa zinthu kumadalira momwe zinthuzo zimagwiritsidwira ntchito, osati dzina la chinthucho lokha.

2. Kodi chitsulo chosapanga dzimbiri cha 316 chili ndi mphamvu kuposa 304?

Mu mitundu yambiri ya zinthu zophimbidwa, 304 ndi 316 zimakhala ndi mphamvu yofanana ya makina. Ubwino waukulu wa 316 si mphamvu yochulukirapo, koma kukana dzimbiri bwino m'malo okhala ndi chloride komanso malo owopsa kwambiri.

3. N’chifukwa chiyani chitsulo chosapanga dzimbiri cha 316 chili chokwera mtengo kuposa 304?

316 nthawi zambiri imadula mtengo chifukwa imakhala ndi nickel yambiri ndipo imakhala ndi molybdenum. Zinthu zosakaniza izi zimathandizira kukana dzimbiri komanso zimawonjezera mtengo wa zinthu zopangira. Ngati kugwiritsa ntchito sikufunikira kukana dzimbiri kwa 316, 304 ikhoza kukhala yotsika mtengo.

4. Kodi ndiyenera kugwiritsa ntchito 304 kapena 316 pa ntchito zakunja?

Pa malo abwinobwino akunja, 304 ikhoza kukhala yovomerezeka. Pa malo a m'mphepete mwa nyanja, m'nyanja, mchere wochotsa icing kapena mankhwala, 316 nthawi zambiri imalimbikitsidwa chifukwa cha kukana bwino kwa chloride ndi dzimbiri. Kumaliza ndi kukonza pamwamba kumakhudzanso mawonekedwe a nthawi yayitali.

5. Kodi zida zolumikizidwa ziyenera kugwiritsa ntchito 304L kapena 316L m'malo mwa 304 kapena 316?

Pazinthu zolumikizidwa, 304L ndi 316L nthawi zambiri zimakondedwa chifukwa mpweya wochepa umathandiza kuchepetsa chiopsezo cha kukhudzidwa ndi zinthu zomwe zimakhudzidwa ndi zinthuzo pambuyo pozilumikiza. Ngati chinthucho chidzalumikizidwa kwambiri kapena kugwiritsidwa ntchito pozilumikiza pambuyo pozilumikiza, ogula ayenera kutsimikizira ngati chizindikiro cha L chikufunika.

6. Kodi ogula angatsimikizire bwanji ngati zinthuzo ndi 304 kapena 316?

Ogula ayenera kuyang'ana EN 10204 3.1 MTC, nambala ya kutentha, chizindikiro cha mankhwala ndi kapangidwe ka mankhwala. Kuyesa kwa PMI n'kothandiza kwambiri chifukwa kumatha kutsimikizira kuchuluka kwa chromium, nickel ndi molybdenum. Kupezeka kwa molybdenum kumathandiza kusiyanitsa 316 ndi 304.

7. Ndi mfundo ziti zomwe zimafunika kuti munthu apereke mawu ofulumira?

Funso lonse liyenera kuphatikizapo giredi, muyezo, mawonekedwe a chinthu, kukula, kuchuluka, kutha kwa pamwamba, kulolerana, satifiketi, mayeso, doko lopita ndi zofunikira pakulongedza.
