Ibyuma bitagira umwanda 304 1.4301

Ibyuma bitagira umwanda 304 hamwe nicyuma 304L bizwi kandi nka 1.4301 na 1.4307. Ubwoko 304 nuburyo bwinshi kandi bukoreshwa cyane ibyuma bidafite ingese. Biracyavugwa rimwe na rimwe n'izina ryayo rya kera 18/8 rikomoka ku mazina y'ubwoko bwa 304 ari 18% chromium na 8% nikel. Andika 304 ibyuma bidafite ingese nicyiciro cya austenitis gishobora gushushanywa cyane. Uyu mutungo watumye 304 iba urwego rwiganje rukoreshwa mubisabwa nka sink na sosi. Andika 304L ni verisiyo ya karubone yo hasi ya 304. Ikoreshwa mubice bipima uburemere kugirango weldable. Ibicuruzwa bimwe nkibisahani hamwe nimiyoboro irashobora kuboneka nkibikoresho “byemewe bibiri” byujuje ibisabwa kuri 304 na 304L. 304H, ibintu byinshi birimo karubone, iraboneka no gukoreshwa mubushyuhe bwinshi. Ibintu byatanzwe muriyi mpapuro birasanzwe kubicuruzwa bizengurutswe na ASTM A240 / A240M. Nibyiza gutegereza ibisobanuro muribi bipimo bisa ariko ntabwo byanze bikunze bihuye nibyatanzwe muriki gitabo.

Amashanyarazi

Icyuma kitagira umuyonga 1.4301 / 304 nacyo gihuye na: S30400, 304S15, 304S16, 304S31 na EN58E.

Kurwanya ruswa

304 ifite imbaraga zo kurwanya ruswa ishobora kuba ibidukikije kandi iyo ihuye nibitangazamakuru bitandukanye byangirika. Gutobora no gutobora bishobora kugaragara mubidukikije birimo chloride. Gucika intege bishobora kugaragara hejuru ya 60 ° C.

Kurwanya Ubushyuhe

304 ifite imbaraga zo kurwanya okiside muri serivisi zigihe gito kugeza kuri 870 ° C no muri serivisi zihoraho kugeza kuri 925 ° C. Ariko, gukoresha ubudahwema kuri 425- 860 ° C ntabwo byemewe. Murugero 304L irasabwa kubera kurwanya imvura igwa. Aho imbaraga nyinshi zisabwa mubushyuhe buri hejuru ya 500 ° C kandi kugeza kuri 800 ° C urwego 304H birasabwa. Ibi bikoresho bizagumana imbaraga zo kurwanya ruswa.

Ibihimbano

Guhimba ibyuma byose bitagira umwanda bigomba gukorwa gusa nibikoresho byabugenewe ibikoresho byuma. Ibikoresho hamwe nubuso bwakazi bigomba gusukurwa neza mbere yo kubikoresha. Izi ngamba zirakenewe kugirango twirinde kwanduza ibyuma bitagira umwanda ukoresheje ibyuma byangiritse byoroshye bishobora guhindura ibara ryibicuruzwa byahimbwe.

Gukora Ubukonje

304 ibyuma bidafite ingese byoroshye gukora cyane. Uburyo bwo guhimba burimo gukora ubukonje bushobora gusaba icyiciro cya annealing hagati kugirango ugabanye akazi gakomeye kandi wirinde kurira cyangwa guturika. Kurangiza ibihimbano hagomba gukoreshwa igikorwa cyuzuye cya annealing kugirango ugabanye imihangayiko yimbere no kunoza ruswa.

Gukora Bishyushye

Uburyo bwo guhimba nko guhimba, burimo gukora bishyushye bigomba kubaho nyuma yo gushyuha kimwe kugeza 1149-1260 ° C. Ibigize ibihimbano bigomba gukonjeshwa byihuse kugirango birinde ruswa.

Imashini

304 ifite imashini nziza. Imashini irashobora kongererwa imbaraga ukoresheje amategeko akurikira: Gukata impande bigomba guhora bikarishye. Impande zijimye zitera akazi karenze. Gukata bigomba kuba byoroshye ariko byimbitse bihagije kugirango wirinde akazi gukomera kugendera hejuru yibikoresho. Chip breakers igomba gukoreshwa kugirango ifashe mugukomeza swarf ikomeza kuba mukazi. Ubushyuhe buke bwumuriro wa austenitike bivamo ubushyuhe bwibanda kumpera. Ibi bivuze ko ibicurane n'amavuta ari ngombwa kandi bigomba gukoreshwa kubwinshi.

Kuvura Ubushuhe

304 ibyuma bidafite ingese ntibishobora gukomera no kuvura ubushyuhe. Kuvura igisubizo cyangwa annealing birashobora gukorwa no gukonjesha vuba nyuma yo gushyushya 1010- 1120 ° C.

Weldability

Imikorere yo gusudira ya fusion kubwoko 304 ibyuma bidafite ingese nibyiza haba hamwe kandi bituzuye. Basabwe kuzuza inkoni hamwe na electrode yicyuma 304 nicyiciro 308 ibyuma bitagira umwanda. Kuri 304L usabwa kuzuza ni 308L. Ibice bikomeye byo gusudira birashobora gusaba nyuma yo gusudira. Iyi ntambwe ntabwo isabwa kuri 304L. Icyiciro cya 321 gishobora gukoreshwa niba kuvura ubushyuhe nyuma ya weld bidashoboka.
