Ibyuma bitagira umuyonga 304 (bikunze kwandikwa nka SUS304 cyangwa AISI304) nicyo cyuma gikoreshwa cyane kandi gihindagurika austenitike ibyuma bitagira umuyonga kwisi. Icyiciro cyacyo cyigishinwa ni 06Cr19Ni10. Ibikurikira biratanga ibisobanuro birambuye kubigize imiti, imiterere yubukanishi, hamwe nimirima ikoreshwa ya Steelless Steel 304.
I. Ibigize imiti
Kurwanya ruswa hamwe nubukanishi bwa Steelless Steel 304 bigenwa nuburyo bwuzuye bwimiti. Ibice nyamukuru bigize ibice (ukurikije ASTM A240 ubuziranenge) nibi bikurikira:
| Ikintu | Urutonde rwibirimo (wt%) | Igikorwa nyamukuru |
| Chromium (Cr) | 18.0–20.0% | Ikintu cyibanze: Ikora chromium oxyde yuzuye ya pasiporo, itanga imitungo "idafite ingese" hamwe no kurwanya ruswa. |
| Nickel (Ni) | 8.0-10.5% | Ikintu cyingenzi: Gutezimbere imiterere ya austenitis, itanga ubukana buhebuje, kutagira magnetisme, gusudira, hamwe no kurwanya ruswa. |
| Carbone (C) | ≤0.08% | Kongera imbaraga. Nyamara, ibintu byinshi bya karubone birashobora kuganisha byoroshye kwangirika hagati yo gusudira, biganisha ku iterambere rya karubone nkeya 304L. |
| Manganese (Mn) | ≤2.0% | Kunoza imbaraga no gusimbuza igice uruhare rwa nikel. |
| Silicon (Si) | ≤ 0,75% | Gukora nka deoxidizer kandi itezimbere imbaraga zubushyuhe bwo hejuru. |
| Fosifore (P) | ≤0.045% | Ikintu cyanduye, gisaba kugenzura (kugabanya ubukana). |
| Amazi (S) | ≤0.030% | Ikintu cyanduye, gisaba kugenzura (bigira ingaruka kumikorere ishyushye). |
| Azote (N) | ≤0.10% | Irashobora kuzamura imbaraga, cyane cyane kuri 304L. |
| Icyuma (Fe) | Kuringaniza | Ibyuma shingiro. |
Itandukaniro mubigize imiti yibyiciro bikomoka:
304L: Carbone (C) ≤ 0,03%, bigabanya cyane ibyago byo gukangurira gusudira.
304H: Carbone (C) 0.04–0,10%, yagenewe kuzamura imbaraga zubushyuhe bwo hejuru no gukora neza.
II. Ibikoresho bisanzwe bya mashini
Ubusanzwe icyumba-ubushyuhe bwubukanishi bwibikoresho bya Stainless Steel 304 mubisubizo-bifatanye (ibintu bikunze gutangwa) nibi bikurikira:
| Ibipimo byerekana imikorere | Agaciro gasanzwe | Ibisobanuro |
| Imbaraga | 15515 MPa | Imbaraga ntarengwa zingirakamaro ibikoresho birashobora kwihanganira mbere yo kuvunika. |
| Gutanga Imbaraga (0.2% offset) | ≥205 MPa | Ingingo ihangayikishije ibikoresho bitangira guhinduka burundu. |
| Kurambura (Uburebure bwa 50mm) | ≥40% | Ikimenyetso cyingenzi: Kurambura cyane birerekana plastike nziza nubukomere, byoroshye gukora inzira ikonje ikonje nko gushushanya byimbitse no kunama. |
| Gukomera (Brinell Gukomera HB) | ≤201 HB | Ugereranije ubukana buke, byerekana imyumvire ikomeye yo gukomera kumurimo (biba bigoye mugihe cyo gutunganya). |
| Modulus ya Elastique | ~ 193 GPa | Bisa nicyuma cya karubone, igipimo cyo gukomera kubintu. |
| Ubucucike | ~ 7.93 g / cm³ | Hasi gato ugereranije nicyuma cya karubone. |
Ibiranga ingenzi:
Ntabwo ari magnetique: Ntabwo ari magnetique muburyo bwuzuye. Ariko, nyuma yo gukora ubukonje (nko gukata, kunama, kashe), austenite irashobora guhinduka martensite, bikaviramo imbaraga za magnetisme. Ubunyangamugayo ntibukwiye gucirwa urubanza gusa na magnetism.
Gukomera: Byihuse gukomera no gukomera mugihe gikonje, ariko plastike iragabanuka. Gukora ibintu bigoye birashobora gusaba guhuza hagati.
III. Imirima nyamukuru yo gusaba
Kubera imikorere myiza muri rusange, Steel Steel 304 ikoreshwa mubikorwa hafi yinganda zose nubuzima bwa buri munsi:
| Umwanya wo gusaba | Porogaramu yihariye | Impamvu zo Guhitamo 304 |
| Ibikoresho byo guteka & Inganda | Inkono, ibikombe, ibase, ibyombo, ibicuruzwa; ibikoresho byo gutunganya ibiryo, ibigega byo kubikamo, imiyoboro, ibikoresho byo kugaburira. | Umutekano & Isuku: Irwanya ruswa, yoroshye kuyisukura, nta bintu byangiza (ibiryo-by-ibiryo). |
| Ubwubatsi & Imitako | Urukuta rw'umwenda, urugi / idirishya ibyuma, intoki, imitako ya lift, igisenge, ibice byubaka. | Ubwiza & Buramba: Ubwoko butandukanye bwubuso burangira (bwogejwe, indorerwamo, umusenyi), birwanya kwangirika kwikirere, kuramba. |
| Ibikoresho byo mu nganda & Imiti | Ibigega byo kubika, guhanahana ubushyuhe, kuvoma, imiyoboro ya reaction (kubitangazamakuru bitangirika cyane), imashini yimyenda / impapuro. | Kurwanya Ruswa Rusange: Kurwanya neza imiti myinshi yimiti n’ibidukikije, gukora neza. |
| Ibikoresho byo mu rugo | Imashini imesa ingoma, ibyuma bishyushya amazi, ibyuma bya microwave, ibyuma bya firigo, ibikoresho byoza ibikoresho. | Kurwanya ubushuhe / kwangirika kwamazi, gushimisha ubwiza, imbaraga nyinshi. |
| Ubwikorezi | Imodoka yimodoka, gari ya moshi imbere, ibice bya kontineri, ibice bya sisitemu. | Kurwanya ikirere cyiza, byoroshye gukora no gusudira. |
| Ubuvuzi & Pharmaceutical | . | Biroroshye koza no guhagarika, birwanya kwanduza indwara. |
| Ingufu & Ibidukikije | Ibice bya gazi ya disulfurizasi, ibice bidafite ingufu mu mashanyarazi ya kirimbuzi, imirasire y'izuba. | Imikorere yizewe mubidukikije byangirika. |
IV. Incamake
Ibyuma bitagira umuyonga 304, bitewe nuburinganire bwimiti (18/8 chromium-nikel), bitanga imbaraga zo kurwanya ruswa, uburyo butagereranywa, hamwe no gusudira, bigatuma biba "ibyuma rusange." Nibihitamo byubukungu kandi byizewe mubenshi mubidukikije bisanzwe. Gusa iyo uhuye nibidukikije bya chloride (nk'amazi yo mu nyanja, umunyu wa de-icing) cyangwa ibitangazamakuru byangiza imiti byangiza, birakenewe ko harebwa kuzamura molybdenum irimo 316 ibyuma bitagira umwanda.
