Chii chinonzi Austenitic Stainless Steel?

Austenitic Stainless simbi ndeimwe yeanonyanya kushandiswa marudzi eStainless simbi mumaindasitiri nekuda kwekunakisisa kwayo corrosion resistance, formability, uye non-magnetic properties. Kunyangwe iwe uri kuita zvekuvaka, kugadzira chikafu, kugadzira makemikari, kana kugadzirwa kwemidziyo yekurapa, ungangosangana neaustenitic stainless simbi usingazvizivi.

Munyaya ino yakazara, tichatsanangurachii chinonzi austenitic simbi isina tsvina, maitiro ayo anokosha, kuti anofananidzwa sei nemamwe marudzi esimbi isina tsvina, uye maitiro ayo. Kana iwe uri mutengi wezvinhu kana mainjiniya uchitsvaga kujeka pakusarudza simbi chaiyo, gwara rino kubvasakysteelichakubatsira kuita zvisarudzo zvine ruzivo.

1. Tsanangudzo: Chii chinonzi Austenitic Stainless Steel?

Austenitic Stainless simbi chikamu chesimbi isina tsvina inotsanangurwa neiyoface-centered cubic (FCC) chimiro chekristaro, anozivikanwa saaustenite phase. Ichi chimiro chakagadzikana pane zvese tembiricha uye chinochengetwa kunyangwe mushure mekutonhora kubva mukupisa kwakanyanya.

Austenitic Stainless simbi dziriisiri-magnetic mune annealed mamiriro, vanehigh chromium (16–26%)uyenickel (6–22%)zviri mukati, uye kupasuperior corrosion resistance, kunyanya mukuenzanisa nedzimwe mhuri dzesimbi dzisina tsvina.

2. Kuumbwa Kwemakemikari

Iyo yakasarudzika zvimiro zve austenitic Stainless simbi inouya kubva mukugadzirwa kwayo kwemakemikari:

  • Chromium: Inopa corrosion resistance uye inoumba inodzivirira oxide layer pamusoro.

  • Nickel: Inodzikamisa iyo austenitic chimiro uye inovandudza ductility.

  • Molybdenum (kusarudza): Inovandudza kuramba kwegomba uye crevice corrosion munzvimbo dzechloride.

  • Nitrogen: Inowedzera simba uye kusagadzikana kwekuora.

  • Carbon (yakaderera zvikuru): Inodzorwa kudzivirira kunaya kwecarbide uye kuchengetedza kushora.

Magiredhi akajairwa se304 uye 316 simbi isina tsvina chikamu cheboka iri.

3. Hunhu Hunokosha hweAustenitic Stainless Steel

1. Yakanakisa Corrosion Resistance

Austenitic Stainless steels inopokana zvakanyanya neyakasiyana siyana yekuora nharaunda. Izvi zvinosanganisira ngura yemuchadenga, kuratidzwa kwechikafu uye zvinwiwa, uye makemikari ane hukasha kusvika pakati nepakati.

2. Zvisiri-Magineti Properties

Mune annealed mamiriro, austenitic Stainless simbi kazhinji isiri-magnetic. Nekudaro, kushanda kunotonhora kunogona kuunza zvishoma magineti nekuda kwekuumbwa kwemartensite.

3. Zvakanaka Weldability

Aya masimbi anogona kugadzirwa nyore nyore uchishandisa akajairika welding matekiniki. Kunyatsotarisirwa kunogona kudikanwa kudzivirira kunaya kwecarbide mune mamwe mamakisi.

4. High Ductility uye Kuoma

Austenitic mamakisi anogona kudhonzwa, kukotama, uye kuumbwa kuita akasiyana maumbirwo pasina kutsemuka. Vanochengeta kuomarara pane ese ari maviri epamusoro uye akadzika tembiricha.

5. Hapana Kuomesa Kupisa

Kusiyana martensitic Stainless simbi, austenitic mamakisi haagone kuomeswa nekupisa kurapwa. Ivo vanowanzoomeswa nekushanda kunotonhora.

4. Magiredhi Akajairwa eAustenitic Stainless Steel

  • 304 (UNS S30400)
    Inonyanya kushandiswa simbi isina tsvina. Yakanakisa corrosion kuramba, yakanaka formability, yakakodzera kune akawanda maindasitiri.

  • 316 (UNS S31600)
    Iine molybdenum yekusimudzira kusimba kwekuora, kunyanya munzvimbo dzechloride dzakaita semugungwa kana mahombekombe.

  • 310 (UNS S31000)
    Kudzivirira kwekushisa kwepamusoro, kunoshandiswa muzvikamu zvevira uye zvinopisa zvinopisa.

  • 321 (UNS S32100)
    Yakasimbiswa netitanium, yakanakira kutonhora kwepamusoro-soro uko kune carbide kunaya kuri kunetseka.

Imwe neimwe yemagiredhi aya inowanikwa nenzira dzakasiyana siyana semashiti, mapaipi, mabara, uye mafittings, uye anogona kupihwa nesakysteelnezvezvido zveprojekiti yako.

5. Zvishandiso zveAustenitic Stainless Steel

Kutenda kune yavo yakaenzana zvivakwa, austenitic Stainless simbi dzinoshandiswa munzvimbo dzakasiyana siyana:

1. Indasitiri Yezvokudya Nezvinwiwa

304 uye 316 inowanzoshandiswa kugadzira chikafu, matangi, uye midziyo nekuda kwehutsanana uye kusagadzikana kwekuora.

2. Chemical uye Pharmaceutical Indasitiri

316L inofarirwa nemareactors, pombi, uye mavharuvhu akafumurwa kumakemikari nekuda kwekupokana kwayo nekloridi.

3. Zvishandiso zvekurapa uye zvekuvhiya

Nekuda kwehutsanana hwavo uye biocompatibility, austenitic Stainless simbi dzinoshandiswa pakuvhiya maturusi, implants, uye midziyo yechipatara.
