I-UNS S31703 ingenasici

I-317L iyinsimbi engagqwali ene-molybdenum ene-austenitic ekhuphuka kakhulu ukumelana nokuhlaselwa kwamakhemikhali uma kuqhathaniswa nezinsimbi ezingenasici ze-chromium-nickel austenitic ezivamile ezifana no-Type 304. I-317L alloy iphinde inikeze ukukhuphuka okuphezulu, ukucindezelwa ukudabuke, namandla aqinile emazingeni okushisa aphakeme kunezinsimbi ezivamile ezingenasici. I-alloy inekhabhoni ephansi ukuze inikeze ukumelana nokuzwela ngesikhathi sokushisela nezinye izinqubo ezishisayo. Le alloy ihloselwe izimo zesevisi ezinzima ezifana nezinhlelo ze-flue gas desulfurization (FGD).

Ukwakheka Kwamakhemikhali - Insimbi Engagqwali 317/317L

Izakhiwo Zemishini Ejwayelekile- Insimbi Engagqwali 317L

317L(1.4438) Impahla Ejwayelekile

I-alloy 317LMN kanye ne-317L amashubhu ensimbi engagqwali e-molybdenum ene-austenitic ekhuphuka kakhulu ukumelana nokuhlaselwa kwamakhemikhali uma kuqhathaniswa nepayipi elivamile le-chromium-nickel austenitic yensimbi engagqwali efana ne-Alloy 304. Ngaphezu kwalokho, i-317LMN ne-317L ingxubevange inikeza i-creep ephakeme kakhulu. -ukuphuka, namandla aqinile emazingeni okushisa aphakeme kunezinsimbi ezingenasici ezivamile. Wonke amamaki ekhabhoni ephansi noma "L" ukuze anikeze ukumelana nokuzwela ngesikhathi sokushisela nezinye izinqubo ezishisayo.

Izibizo ezithi "M" kanye "N" zibonisa ukuthi ukuqanjwa kuqukethe amazinga anyukile e-molybdenum ne-nitrogen ngokulandelanayo. Inhlanganisela ye-molybdenum ne-nitrogen isebenza kahle kakhulu ekwandiseni ukumelana nokugqwala kwemigodi nokugqwala, ikakhulukazi emifudlaneni equkethe ama-asidi, ama-chlorides, nezinhlanganisela zesulfure emazingeni okushisa aphakeme. I-nitrogen iphinde isebenze ekwandiseni amandla alawa ma-alloys. Womabili ama-alloys enzelwe izimo zesevisi ezinzima ezifana nezinhlelo ze-flue gas desulfurization (FGD).

Ngaphezu kwezakhiwo ezinhle kakhulu zokumelana nokugqwala kanye namandla, ama-alloys angu-316, 316L, kanye nama-317L Cr-Ni-Mo ahlinzeka ngokwenziwa okuhle kakhulu nokwakheka okujwayelekile kwamashubhu ensimbi engenasici ye-austenitic.

317L (1.4438) Ukwelashwa Kokushisa
Anealing
Ipayipi lensimbi engagqwali ye-austenitic inikezwe esimweni sokugaya i-annealed isilungele ukusetshenziswa. Ukwelashwa kokushisa kungase kudingeke ngesikhathi noma ngemva kokwenziwa ukuze kukhishwe imiphumela yokwakheka okubandayo noma ukuncibilikisa ama-chromium carbides anciphile ngenxa yokuchayeka okushisayo. Kuma-Alloys 316 kanye no-317L i-anneal yesixazululo yenziwa ngokufudumeza ku-1900 kuya ku-2150°F (1040 kuya ku-1175°C) ibanga lokushisa okulandelwa ukupholisa komoya noma ukucisha amanzi, kuye ngobuningi besigaba. Ukupholisa kufanele kusheshe ngokwanele ngo-1500 kuya ku-800°F (816 kuya ku-427°C) ukuze kugwenywe ukunatha kabusha kwe-chromium carbides futhi kunikeze ukumelana nokugqwala okukhulu. Kuzo zonke izimo, insimbi kufanele ipholiswe kusukela ekushiseni kwe-anneal kuya ekushiseni okumnyama ngaphansi kwemizuzu emithathu.

Ukuqamba
Ibanga lokushisa lokuqala elinconyiwe lingu-2100-2200°F (1150-1205°C) nebanga lokuqeda elingu-1700-1750°F (927-955°C).

Anealing
I-317LMN kanye ne-Alloy 317L izinsimbi ezingenasici zingabanjwa ebangeni lokushisa elingu-1975-2150°F (1080-1175°C) kulandele ukupholisa komoya noma ukucisha amanzi, kuye ngokujiya. Amapuleti kufanele afakwe phakathi kuka-2100°F (1150°C) no-2150°F (1175°C). Insimbi kufanele ipholiswe ekushiseni kwe-anneal (kusuka kokubomvu/kumhlophe kuya kumnyama) ngaphansi kwemizuzu emithathu.

Ukuqina

• Lawa mabanga awaqini ngokuphathwa ukushisa.
• I-alloys 316 kanye ne-317L yeshubhu yensimbi engagqwali ayikwazi ukwenziwa lukhuni ngokwelashwa kokushisa.

FAQ
Q: Ingabe uhweba inkampani noma umenzi?
A:Siyinkampani yokuhweba enesipiliyoni seminyaka engaphezu kwe-15 ebhizinisini lokuthekelisa insimbi, sinokubambisana kwesikhathi eside nezigayo ezinkulu eChina.
Q:Ingabe uzoletha izimpahla ngesikhathi?
A:Yebo, sithembisa ukuhlinzeka ngemikhiqizo yekhwalithi engcono kakhulu kanye nokulethwa ngesikhathi.Ukwethembeka kuyimfundiso yenkampani yethu.
Q:Ingabe uyawahlinzeka ngamasampula?ingabe amahhala noma angeziwe?
IMP: Isampula ingahlinzeka ikhasimende mahhala, kodwa impahla ye-courier izokhandwa yi-akhawunti yekhasimende.
Q:Ingabe uyakwamukela ukuhlolwa komuntu wesithathu?
A: Yebo siyakwamukela.
Q:Yimiphi imikhiqizo yakho eyinhloko?
A:Insimbi ye-Carbon, i-alloy steel, ipuleti lensimbi engagqwali/coil, ipayipi nokufakwa, izigaba njll.
Q: Ungakwazi yini ukwamukela oda customzied?
A: Yebo, siyaqinisekisa.
