Ibyuma bitagira umuyonga 316 (ASTM S31600 yo muri Amerika, Igishinwa 06Cr17Ni12Mo2) ni molybdenum irimo ibyuma bya austenitike bitagira umuyonga, bakunze kwita "ibyuma byo mu nyanja byo mu nyanja" kubera kurwanya ruswa. Ishingiye ku byuma 304 bidafite ingese hiyongereyeho 2-3% ya molybdenum (Mo), ibyo bikaba byongera cyane kurwanya kurwanya imyobo no kwangirika.
Ⅰ.Key Ibiranga
1.Kurwanya ruswa idasanzwe: Kwiyongera kwa molybdenum itanga imikorere isumba ibidukikije bya chloride (urugero, amazi yinyanja, spray yumunyu), hamwe no kurwanya pitingi irenze kure iy'ibyuma 304 bitagira umwanda. Igipimo cyacyo cya 10% acide sulfurike irashobora kuba munsi ya 0.1 mm / mwaka.
2.Imikorere yo hejuru-Ubushyuhe.
3.Ibikoresho bya mashini: Gutanga imbaraga ≥205 MPa, imbaraga zingana ≥515 MPa, kurambura ≥40%, gutanga ubukana bwiza nubushobozi bwo kunaniza akazi.
4.Kureka Magnetism: Non-magnetique muburyo bwo gukemura; irashobora guhinduka magnetiki gato nyuma yo gukora ubukonje. Birakwiriye kubikoresho byunvikana kumashanyarazi.
Ⅱ.Ibigize imiti (Ibipimo byingenzi)
| Ikintu | Urutonde rw'ibirimo | Imikorere |
| Carbone (C) | ≤0.08% | Igenzura ruswa |
| Chromium (Cr) | 16.0-18.0% | Gukora firime ya pasiporo, irinda ingese |
| Nickel (Ni) | 10.0-14.0% | Ihindura imiterere ya austenitis, irwanya aside |
| Molybdenum (Mo) | 2.0-3.0% | Ikintu cyibanze, gitanga guhangana |
| Manganese (Mn) | ≤2.00% | Deoxidizer |
| Silicon (Si) | ≤ 0,75% | Deoxidizer |
Ⅲ.Ibikoresho bisanzwe bya mashini
Ibyumba Ubushyuhe bwa Byumba Ibikoresho (Igisubizo-Leta ifatanye)
Nibisanzwe bikunze kugaragara kuri 316 ibyuma bidafite ingese, bitanga impirimbanyi nziza.
| Umutungo | Agaciro gasanzwe | Ibisabwa bisanzwe (ASTM A240) |
| Imbaraga zingana (Rm) | 515 - 620 MPa | 15 515 MPa |
| Imbaraga Zitanga (Rp0.2) | 205 - 310 MPa | 5 205 MPa |
| Kurambura (A) | 40% - 50% | ≥ 40% |
| Gukomera (HBW) | 149 - 217 | ≤ 217 |
| Modulus ya Elastike (E) | 193 GPa | - |
Inyandiko:
1.Imbaraga Ziciriritse: Tanga imbaraga hafi 200-300 MPa, byoroshye gukora no gutunganya.
2.Plastique nziza: Kurambura mubisanzwe birenga 40%, byerekana ubukana bwinshi no kurwanya kuvunika.
3. Gukomera: Imbaraga nubukomezi byiyongera cyane mugihe gikonje gikora (urugero, kuzunguruka gukonje, gushushanya), ariko plastike iragabanuka.
Ⅳ.Ibice byo gusaba mbere
1.Marine Engineering: Ibikoresho byoherejwe, urubuga rwo hanze, ibikoresho bya desalination.
Inganda n’inganda n’inganda: Imashini, imiyoboro, guhinduranya ubushyuhe (birwanya aside / alkalis).
3.Ubuvuzi & Inganda zikora ibiryo: Ibikoresho byo kubaga, ibikoresho bya farumasi, imashini zitunganya ibiryo (byujuje ubuziranenge bwisuku).
4.Ubwubatsi & Imitako: Kubaka urukuta rwumwenda, gariyamoshi mubice byinyanja (birwanya kwangirika kwumunyu).
Ⅴ.Ibyiciro Byakomotseho
316L: Carbone nkeya (C≤0.03%), gusudira neza hamwe no kurwanya ruswa hagati, bikwiranye nibice biremereye byo gusudira.
316H: Imiterere-ya-karubone, imbaraga-zohejuru zo hejuru, zikwiranye nubushyuhe bwo hejuru-butwara ibintu.
