304 vs 304L Icyuma kitagira umuyonga: Itandukaniro na Porogaramu

2025-04-16

Icyiciro cya 304 na 304L ibyuma bitagira umuyonga biza mu myanya ikunzwe cyane ya austenitis, ihabwa agaciro kubera kurwanya ruswa no guhuza n'imiterere. Guhitamo igikwiye bisobanura gusobanukirwa neza - ariko ni ngombwa - itandukaniro muri chimie n'imikorere. Aka gatabo gakurikiza imiterere imenyerewe - ibigize, imitungo, gusudira, gusaba, hamwe nigiciro - mugihe utanga icyerekezo gishya kigufasha guhitamo neza. 304 vs 304L

Ibigize imiti ya 304 na 304L Ibyuma bitagira umwanda

304 Icyuma
- Carbone (C): kugeza 0.08%
- Chromium (Cr): 18-20%
- Nickel (Ni): 8-10.5%
304L Icyuma
- Carbone (C): kugeza 0,03%
- Chromium (Cr): 18-20%
- Nickel (Ni): 8-12%

Guhinduka kugaragara ni karubone. 304L irwanya karubone, 304L irwanya ishyirwaho rya karubide ya chromium ku mbibi z’ingano mu gihe cyo gusudira, ikarinda kurwanya ruswa. .

Kugereranya Ibintu bifatika na mashini

Umutungo	304	304L	Icyo Bisobanura
Imbaraga za Tensile (MPa)	~ 520–750	~ 485–690	304 ikurura cyane, ariko byombi birenze ibikenewe
Imbaraga Zitanga (MPa)	~ 205-22	~ 170–200	Gucisha bugufi kuri 304 kuburemere - gutwara porogaramu
Kurambura (%)	≥ 40	≥ 40	Kurambura bihebuje muri byombi kugirango bibe byoroshye
Gukomera (Brinell)	~ 70-90	~ 65–85	Hafi ya kimwe muburyo busanzwe bukoreshwa
Kurwanya ruswa	Nibyiza (ibidukikije rusange)	Ikirenga mubice byasuditswe	304L imurika post - gusudira nta kuvura ubushyuhe bwiyongera

Gusudira no guhimba

Weldability
Amavuta yombi asudira byoroshye nuburyo busanzwe. Nyamara, 304L ya make ya karubone isobanura ko ushobora gusimbuka post - weld annealing - gutakaza umwanya n'imbaraga.

Imashini
Austenitike idafite ibyuma bikunda gukora - gukomera. Kurwanya kuganira no kwambara ibikoresho bidashyitse, koresha impande zogukata, igipimo cyibiryo giciriritse, hamwe namavuta ahagije. 304L yoroshye gato irashobora gutanga kurangiza neza mubihe bimwe.

Porogaramu ya 304 na 304L Ibyuma

304 Icyuma

Igikoni cyubucuruzi cyarohamye, ibikoresho byo guteka, nibikoresho byo gutunganya ibiryo
Ibishushanyo mbonera byubaka (urugero, gariyamoshi, kwambara)
Ibikoresho byo kubika hamwe n'ibipimo bingana ubushyuhe

304L Icyuma

Gutunganya imiti no kuvoma peteroli (imashini nini yo gusudira)
Guhindura ubushyuhe hamwe na kondenseri (ubudakemwa bwa weld)
Ibigega bya farumasi n’amata (kuvugurura kenshi gusudira)

Igiciro no Kuboneka

Igiciro
Tegereza 304L gutwara premium yoroheje - mubisanzwe hejuru ya 3-7% - byerekana inyungu nkeya ya karubone mu nteko zasuditswe. Ku bicuruzwa binini, iryo tandukaniro rirashobora kwiyongera, bityo rero shyira muri bije yawe.

Kuboneka
Ibyiciro byombi nibyingenzi murwego rwo gutanga ibyuma: impapuro, amasahani, utubari, tubing, nibindi byinshi murwego runini. Ibihe bisanzwe byo kuyobora ni bigufi, ariko kuburyo bwihariye cyangwa inyongera - ibice byimbitse, teganya mbere.

Umwanzuro

Icyiciro cya 304 na 304L bisangiye umugongo rusange wo kurwanya ruswa no guhinduka. Icyemezo cyawe gishingiye kubisabwa byo gusudira nibisabwa na serivisi: hitamo 304L mugihe ugabanije post - gutunganya ubushyuhe bwo gusudira no kugabanya weld - kurwanya ruswa ni byo byihutirwa; hitamo 304 niba ukeneye imbaraga nkeya kuri rusange - intego ibice. Hamwe niterambere ryoguhuza ikorana buhanga hamwe niterambere rirambye, ibivanze byombi bizakomeza kuba urugo rwakazi mu nganda mumyaka iri imbere.
