SS316 ibyuma bitagira umwanda mubisanzwe bigomba gukoreshwa kuri gari ya moshi zashyizwe hafi yibiyaga cyangwa inyanja.SS304 nibikoresho bisanzwe murugo cyangwa hanze.
Nka amanota y'ibanze ya Amerika AISI, itandukaniro rifatika hagati ya 304 cyangwa 316 na 304L cyangwa 316L nibirimo karubone.
Urwego rwa karubone ni 0.08% ntarengwa kuri 304 na 316 na 0.030% hejuru yubwoko bwa 304L na 316L.
Ibindi bice byose birasa cyane (nikel ya 304 ni 8.00-10.50% naho kuri 304L 8.00-12.00%).
Hano hari ibyuma bibiri byi Burayi byubwoko bwa '304L', 1.4306 na 1.4307.1.4307 ni variant ikunze gutangwa, hanze yubudage.1.4301 (304) na 1.4307 (304L) zifite karubone zingana na 0.07% ntarengwa na 0.030% ntarengwa.Urutonde rwa chromium na nikel birasa, nikel kumanota yombi afite byibuze 8%.1.4306 mubyukuri icyiciro cyubudage kandi gifite 10% byibuze Ni.Ibi bigabanya ferrite yibyuma kandi wasanze bikenewe mubikorwa bimwe na bimwe bya shimi.
Amanota yu Burayi kubwoko bwa 316 na 316L, 1.4401 na 1.4404, bihuye nibintu byose bifite karubone ya 0.07% ntarengwa kuri 1.4401 na 0.030% ntarengwa kuri 1.4404.Hariho na Mo verisiyo ndende (2,5% byibuze Ni) ya 316 na 316L muri sisitemu ya EN, 1.4436 na 1.4432.Kugirango urusheho kugora ibintu, hariho kandi urwego 1.4435 ruri hejuru muri Mo (2,5% byibuze) no muri Ni (12.5% byibuze).
Ingaruka ya karubone mukurwanya ruswa
Carbone yo hepfo 'variants' (316L) yashyizweho nkibisubizo byurwego rwa karuboni (316) kugirango igabanye ingaruka zo kwangirika kwa intercrystalline (kubora weld), byagaragaye nkikibazo muminsi yambere yo gushyira mubikorwa ibyuma.Ibi birashobora kuvamo niba ibyuma bifashwe mubushyuhe bwa 450 kugeza 850 ° C mugihe cyiminota mike, bitewe nubushyuhe hanyuma bikagerwaho nibidukikije byangiza.Ruswa noneho ibera kuruhande rwimbibi.
Niba urwego rwa karubone ruri munsi ya 0.030% noneho kwangirika kwa intercrystalline ntikubaho nyuma yo guhura nubushyuhe, cyane cyane mubihe bisanzwe bikunze kugaragara muri zone yibasiwe nubushyuhe bwo gusudira mubice byibyuma.
Ingaruka yurwego rwa karubone kuri weldability
Hariho kureba ko ubwoko bwa karubone buke byoroshye gusudira kuruta ubwoko bwa karubone.
Ntabwo bisa nkimpamvu isobanutse yibi kandi itandukaniro rishobora kuba rifitanye isano nimbaraga zo hasi yubwoko buke bwa karubone.Ubwoko buke bwa karubone burashobora koroha kubushiraho no kubikora, ibyo nabyo bikaba bishobora no guhindura urwego rwimyitwarire isigaye yasize ibyuma nyuma yo gukora no guhuza gusudira.Ibi birashobora kuvamo ubwoko bwa 'karubone' bwa karubone ikenera imbaraga nyinshi kugirango ibifate mumwanya umaze gushyirwaho gusudira, hamwe nuburyo bwo guhindukira-inyuma niba bidafashwe neza.
Ibikoresho byo gusudira kuri ubwo bwoko bwombi bishingiye ku gipimo gito cya karubone, kugirango wirinde kwandura intercrystalline muri nugget ikomeye cyangwa kuva ikwirakwizwa rya karubone mubyuma byababyeyi (bikikije).
Kwemeza-ibyemezo bibiri bya karubone nkeya
Ibyuma bikorerwa mubucuruzi, ukoresheje uburyo bwo gukora ibyuma bigezweho, akenshi bikozwe nkubwoko bwa karubone nkeya nkikintu cyoroshye kubera kugenzura neza ibyuma bigezweho.Kubwibyo, ibyuma byarangije gutangwa akenshi bitangwa kumasoko 'byemewe bibiri' mubyiciro byombi nkuko bishobora gukoreshwa mubihimbano byerekana icyiciro, murwego runaka.
