Ikhoyili Yensimbi Engagqwali

I-Duplex stainless steel grade 2205 (eyaziwa nangokuthi i-UNS S31803/S32205, ASTM A240 Type 2205, Inox 2205, AISI 318LN, SUS 329J3L, noma EN 1.4462) iyisigaba sesibili esiqukethe cishe i-2–ferritic alloacyte chromium, 2.5–3.5% molybdenum, 4.5–6.5% nickel, futhi cishe 0.15% nitrogen. I-microstructure yayo elinganiselayo inikeza inhlanganisela eyingqayizivele yamandla aphezulu kanye nokumelana nokugqwala okuhle kakhulu. Isibonelo, ibanga elingu-2205 ngokuvamile linamandla aphindwe kabili ensimbi angu-316L, okuvumela abaklami ukuthi basebenzise izingxenye ezincane kakhulu, ezilula ngaphandle kokudela ukusebenza.

Ingxubevange ivamise ukunikezwa kusimo sokufakwa kwesixazululo (nge-ASTM A240/A240M ngayinye) ukuze kugcinwe ukwakheka okuhle kwe-duplex. IBanga 2205 lihlala liqinile kusukela emazingeni okushisa e-cryogenic (cishe -50°C) afinyelele cishe ku +300°C; ngale kwalolu hlu, isigaba se-brittle sigma singakheka kuma-welds. Lezi zakhiwo zenza i-duplex 2205 ibe ukukhetha okuhle kakhulu kwezicelo ezifunwayo ezifana nokucutshungulwa kwamakhemikhali, uwoyela negesi yasogwini, kanye nezindawo zasolwandle lapho kudingeka khona kokubili amandla aphezulu kanye nokumelana nokugqwala kwe-chloride.

I-Incoloy 840 iyingxubevange yokushisa ephezulu kakhulu eyenziwe nge-nickel ne-chromium, ene-iron eyengeziwe, i-aluminium, ne-titanium.. Yenzelwe ukushisa okukhulu nezimo zesevisi ezinzima. I-Incoloy 840 igcina amandla avelele ngisho noma kushisa kakhulu futhi imelana ne-oxidation emoyeni nesitimu, iyenze ibe ilungele izindawo eziyingozi kakhulu..

I-QN1803 insimbi engagqwali ingeyomndeni wakwa-QN owakhiwe yiQingtuo Group, ehlanganisa ne-QN1701, QN1804L, QN1906Mo, kanye ne-QN2109Mo. Njengesizukulwane esilandelayo, i-high-nitrogen austenitic alloy, i-QN1803 yakhelwe ukuvala igebe phakathi kokusebenza nezindleko, inikeze enye indawo ephoqelelayo yensimbi engagqwali engu-304 evamile.

Amakhoyili ensimbi engagqwali angu-430 avame ukuba kazibuthe futhi afaka okuqukethwe kwekhabhoni ephezulu, ewahlukanisa njengensimbi engagqwali ye-ferritic. Azikwazi ukuqina ngokushesha futhi zidinga ukupholisa ngesikhathi somshini. Izindlela zokwelapha ezijwayeleke kakhulu endaweni yamakhoyili ensimbi engagqwali angu-430 yi-2B kanye ne-BA. Kwa-GHT Steel, sisebenzisa imishini ethuthukisiwe ukucubungula amakhoyili ensimbi engagqwali angu-430 kukho kokubili ukugoqeka okubandayo nokugingqeka okushisayo. Ukwengeza, sinikeza amasevisi enziwe ngendlela oyifisayo ukuhlangabezana nezidingo zakho ezithile mayelana nosayizi, amabanga, nokuma.

Ishidi lensimbi engagqwali le-316 laziwa ngokuqukethwe kwalo okuphezulu kwe-nickel, okuvumela ukubunjwa nokudweba kalula. Leli banga lithandwa kakhulu emakethe ngenxa yokumelana nokugqwala okuphakeme, ikakhulukazi uma kuqhathaniswa namanye amabanga.
Kwa-GHT Steel, sinikeza amashidi ensimbi engagqwali amnyama namhlophe angu-316 ane-PVC, sisebenzisa amasu avamile athuthukile kanye ne-laser ukuze kuqinisekiswe ikhwalithi engavamile.

Ikhoyili yensimbi engagqwali engu-301 i-austenitic futhi ayiyona i-magnetic esimweni sayo sokucwiliswa, kodwa iba kazibuthe ngemva kokusebenza okubandayo. Awukwazi ukuqina ngokwelashwa okushisa. Ukwengeza, sinikeza ukwenza ikhoyili ibe ngokwezifiso ngobukhulu, izimo, namabanga ukuze ihlangabezane nezidingo ezithile zamaphrojekthi akho.

Ikhoyili ye-GHT Steel's 201 yensimbi engagqwali isebenza kahle kakhulu ezindaweni ezinokhahlo, iyenze ilungele ukusetshenziswa okuchayeke ekugqwaleni, ama-alkali, namanye amakhemikhali ayingozi. Uma kuqhathaniswa nezinye izinto, ikhoyili yensimbi engagqwali engu-201 inikeza amandla nokuqina okuphezulu.
Izinketho zokucubungula: Okugoqiwe okushisayo, okugoqiwe okubandayo, njll.
Ubude bebanga: 100mm kuya ku-6000mm.
Amandla okuqina: 71,000 MPa.

Njengomphakeli ohamba phambili wensimbi engagqwali e-China, i-Guanghetong (GHT Steel) ithengisa futhi inikezela ngamakhoyili ensimbi engagqwali angu-304 ekhwalithi ephezulu avela ezinkampanini ezidumile, ehlinzeka ngokulethwa ngesikhathi kanye nezintengo ezingcono kakhulu.
