Igisubizo nuko ireme rya316 ibyumani byiza kuruta304 ibyuma, kubera ko ibyuma 316 bidafite ingese byahujwe nicyuma cya molybdenum hashingiwe kuri 304, iki kintu gishobora kurushaho gushimangira imiterere ya molekile yicyuma kitagira umwanda, bigatuma irushaho kwangirika no kurwanya okiside, kandi mugihe kimwe, kurwanya ruswa nayo. yiyongereye cyane.Reka turebe ibyuma 304 bidafite ibyuma na 316 ibyuma bidafite ingese nibyiza.Ubwoko bukoreshwa cyane mubyuma bidafite ingese ni 304 na 316. Sisitemu yo gucunga amanota yakoreshejwe mugutondekanya ubu bwoko bubiri bwibyuma biva cyane cyane muburyo bwo gutanga amakuru yatangijwe n’ishyirahamwe ry’abanyamerika ry’ibyuma n’ibyuma by’Ubushinwa (AISI), rimwe mu rya kera imbaraga zubumwe kugeza ubu kuva muri 1855. Ibi byiciro byerekana ibiyigize, kandi ibyinshi 200 - na 300-by-ibyuma bitagira umuyonga bifatwa nka austenitis.Inzira yo kwikuramo ikubiyemo gushyushya ibyuma, ferroalloy, cyangwa ibyuma kugeza aho imiterere ya kirisiti ihinduka kuva ferrite ikagera kuri austenite.Nubwo bigoye gutandukanya byombi nijisho ryonyine, imitungo idasanzwe yibicuruzwa hagati ya 304 na 316 yinganda zicyuma zishobora gutuma zisumba izindi mubikorwa bya tekiniki.
Kuva iterambere ry’inganda z’Abashinwa mu kinyejana cya 20, amasosiyete y’ibyuma adafite ingese yabaye ibikoresho by’ingenzi mu mishinga myinshi yo mu Bushinwa kubera igihe kirekire, gukora imashini zikoreshwa cyane, gusudira no guhinduka.Irimo ibice byinshi bitandukanye kwijana ryibintu bishinzwe urwego rutandukanye ruzwi.Buri cyiciro gifite umwihariko wacyo, kandi kugereranya hagati yibi byiciro byombi, nkigihe nkibikorwa byabo, ni 304 na 316 ibyuma bitagira umwanda.
Nibyiza, 304 cyangwa 316 ibyuma bidafite ingese
Iyo urebye ubwoko bubiri bwibyuma, birasa mubigaragara hamwe nibigize imiti.Byombi bitanga uburinzi buhebuje bwo kwirinda ingese no kwangirika, mugihe bitanga kandi igihe kirekire.Iyo ugereranije 304 na 316 ibyuma bitagira umwanda, igiciro cyinshi ugereranije nicyanyuma gishobora guterwa no kurwanya ruswa.Bitewe niri tandukaniro ryibiciro hamwe nibidukikije bigarukira ku byuma 316, ibyuma 304 nicyuma gikoreshwa cyane nicyuma cya austenitis.
Icyiciro cya 316 ibyuma bitagira umuyonga bigura byinshi kuberako birwanya ruswa.Kubisabwa aho ibinyomoro bihura nibisubizo bya chlorine na chloride (harimo n’amazi yo mu nyanja y’Ubushinwa), birasabwa cyane cyane ko sisitemu yakoreshwa binyuze muri iyi mavuta hamwe n’amanota meza.Irashobora gukoreshwa mu kongera ubuzima bwa serivise yubuzima bwibigize cyangwa ibikoresho bigenda bihura n’ibidukikije bikabije kandi byangirika, cyane cyane mu bihe bifitanye isano n’umunyu uteye ikibazo.Nyamara, urwego 304 ni ingirakamaro cyane kubisabwa byinshi.Muri make, iyo urebye ibyuma 304 na 316 bitagira umuyonga, kubisabwa bisaba kwangirika kwiza cyangwa kurwanya amazi, koresha ibyuma 316 bitagira umwanda.Kubindi bikorwa, ibyuma 304 bidafite ingese nabyo birakorwa.Muri rusange, 304 na 316 ni code yicyuma kitagira umwanda, mubyukuri, nta tandukaniro riri hagati yabyo ni ibyuma bitagira umwanda, bigabanijwe ni ubwoko butandukanye.Muri make, ubwiza bwibyuma 316 bitagira umuyonga birenze 304 ibyuma bitagira umwanda, 316 ibyuma bitagira umwanda hashingiwe kuri 304 mubyuma bya molybdenum, iki kintu gishobora kurushaho gushimangira imiterere ya molekile yicyuma, bigatuma irushaho kwambara no kurwanya okiside, kuri icyarimwe, kurwanya ruswa nabyo byiyongera cyane.
Ibicuruzwa bifitanye isano
