I-304 kanye ne-316 yizinhlobo zensimbi engagqwali, futhi "ukuqeda" kwazo kubhekisela ekuthunjweni kwendawo noma ukubukeka kwensimbi. Umehluko phakathi kwalezi zinhlobo ezimbili ngokuyinhloko usekubunjweni kwazo kanye nezakhiwo eziwumphumela:

Ukwakhiwa:

304 Insimbi Engagqwali:

Iqukethe cishe u-18-20% we-chromium kanye ne-nickel engu-8-10.5%.
Ingase futhi iqukathe amanani amancane ezinye izakhi ezifana ne-manganese, i-silicon, ne-carbon.

316 Insimbi Engagqwali:

Iqukethe cishe 16-18% chromium, 10-14% nickel, kanye 2-3% molybdenum.
Ukwengezwa kwe-molybdenum kuthuthukisa ukumelana kwayo nokugqwala, ikakhulukazi ngokumelene nama-chloride nezinye izincibilikisi zezimboni.

Izakhiwo Nezicelo:

304 Insimbi Engagqwali:

Ukumelana Nokugqwala: Kuhle, kodwa hhayi phezulu njengo-316, ikakhulukazi ezindaweni ezine-chloride.

Amandla: Amandla aphezulu kanye nokuqina, kuhle ngezinjongo ezijwayelekile.

Izinhlelo zokusebenza: Isetshenziswa kakhulu emishinini yasekhishini, ukucubungula ukudla, i-architectural trim, iziqukathi zamakhemikhali, nokunye ngenxa yokumelana nokugqwala okuhle kanye nokuhlanzeka kalula.

316 Insimbi Engagqwali:

Ukumelana Nokugqwala: Iphakeme kuno-304, ikakhulukazi emanzini anosawoti noma ezindaweni zasolwandle, futhi lapho kukhona ama-chloride.

Amandla: Ifana ne-304 kodwa inokumelana nokugoba okungcono.

Izinhlelo zokusebenza: Ilungele ukusetshenziswa ezindaweni zasolwandle, okokusebenza kwemithi, izimila zezokwelapha, ukucubungula amakhemikhali, nanoma iyiphi indawo lapho kudingeka ukumelana nokugqwala okuphezulu.

Qeda:

"I-finish" yensimbi engagqwali, kungakhathaliseki ukuthi i-304 noma i-316, ibhekisela ekuqedeni okungaphezulu, okungahluka kuye ngenqubo yokukhiqiza. Iziqephu ezijwayelekile zihlanganisa:

1, Cha. 2B: Isiphetho esibushelelezi, esibuthuntu esikhiqizwe ukugoqeka okubandayo okulandelwa ukuhoxisa nokwehliswa.

2, Cha. 4: Isiphetho esibhulashiwe, esifinyelelwa ngokuxubha indawo engaphezulu ngomshini ukuze kwakhe iphethini yemigqa emihle ehambisana nendawo yokuxubha.

3, Cha. 8: Isiphetho esifana nesibuko esikhiqizwe ngokupholishwa ngama-abrasive acolisekileyo alandelanayo kanye nokubhafa.

Zombili izinsimbi ezingenasici ezingama-304 nezingu-316 zingaba nokuqedwa okufanayo, kodwa ukukhetha phakathi kuka-304 no-316 kuzoncika kuzimo ezithile zemvelo kanye nezakhiwo ezidingekayo zohlelo lokusebenza.

Ingabe i-316 noma i-304 ibiza kakhulu?

Ngokuvamile, insimbi engagqwali engu-316 ibiza kakhulu kunensimbi engagqwali engu-304. Isizathu esiyinhloko salo mehluko wamanani ukwakheka kwensimbi engagqwali engu-316, ehlanganisa iphesenti eliphezulu le-nickel kanye nokwengezwa kwe-molybdenum. Lezi zinto zithuthukisa ukumelana nokugqwala kwensimbi engagqwali engu-316, ikakhulukazi endaweni ye-chloride nasolwandle, kodwa futhi zifaka isandla ezindlekweni zezinto ezibonakalayo.

Nasi isifinyezo sezici ezibangela umehluko wezindleko:

Ukubunjwa Kwezinto Ezibalulekile:

304 Insimbi Engagqwali: Iqukethe cishe u-18-20% we-chromium kanye ne-nickel engu-8-10.5%.
316 Insimbi Engagqwali: Iqukethe cishe 16-18% chromium, 10-14% nickel, kanye 2-3% molybdenum.

Ukumelana Nokugqwala:

316 Insimbi Engagqwali: Inikeza ukumelana nokugqwala okuphakeme, ikakhulukazi ngokumelene nama-chloride nasezindaweni zasolwandle, ngenxa yobukhona be-molybdenum.
304 Insimbi Engagqwali: Inokumelana nokugqwala okuhle kodwa ayisebenzi kahle ezindaweni ezonakalisa kakhulu uma kuqhathaniswa no-316.

Izindleko Zokukhiqiza:

Amanani aphezulu e-nickel kanye nokwengezwa kwe-molybdenum ku-316 insimbi engagqwali kubangela ukwanda kwezindleko zempahla eluhlaza.
Izindleko zokucubungula nokukhiqiza zingase zibe phezulu ku-316 insimbi engagqwali ngenxa yokwakheka kwayo kwengxubevange eyinkimbinkimbi.

Ngakho-ke, ngezinhlelo zokusebenza lapho ukumelana nokugqwala okuphezulu kwe-316 insimbi engagqwali kungadingeki, i-304 insimbi engagqwali ivame ukukhethwa njengenye indlela engabizi kakhulu.
