Fe, <0.3% C, 10.5-12.5% ​​Cr, 0.3-1.0% Ni, <1.5% Mn, <1.0% Si, <0.4% P, <0.15% S, <0.03% N
Icyuma kidasanza cya Grade 3CR12 ni icyuma kidasanza cya chromium gihendutse gikozwe mu guhindura imiterere y'icyuma cya Grade 409. Kirwanya ingese nkeya no kwangirika. Cyakozwe bwa mbere na Columbus Stainless Company munsi y'ikirango cyanditswe "3CR12". Andi mazina y'iki cyuma arimo UNS S40977/S41003 na 1.4003.
Izindi ngero zingana n'ingero za 3CR12 zirimo ingero za ASME SA240, ingero za ASTM A240/A240M, na EN 10088.2. Ariko, EN 10028.7 ikubiyemo kandi icyiciro cya 1.4003, kigizwe n'icyuma kitagira umuvuduko mu rwego rwo gushyushya.
Ibice bikurikira bizatanga imiterere y'ingenzi ya coil, urupapuro na plaque bya 3CR12 by'icyuma kitagira umugese bikurikije Euronorm S41003, S40977, ASTM A240/A240M na EN 10088.2 1.4003.
Ibi byavuzwe haruguru ni igereranya gusa. Iyi mbonerahamwe igamije gutanga igereranya ry'ibikoresho bisa mu mikorere, kandi ibipimo ntabwo byemewe n'amategeko. Ibipimo by'umwimerere bishobora kwemezwa niba hakenewe ibipimo bingana neza.
Icyuma kidasanza cya Grade 3CR12 gishobora gukoreshwa mu bikorwa aho aluminium, galvanized cyangwa carbon steel bitanga umusaruro mubi kubera ko birwanya aside ikomeye n'ibice by'ishingiro, ndetse no kwangirika guterwa na chloride stress corrode. Ariko, bitandukanye na Grade 304, Grade 3CR12 ifite ubudahangarwa bwo hasi ku myenge no kwangirika kw'ibice iyo hari chloride.
Mu bihe by’ikirere, urwego rwa 3CR12 rwongereye ubushobozi bwo kwihanganira amazi na chloride, kuko ubushyuhe bw’ingano ya chloride bugabanuka hakoreshejwe ioni za nitrati na sulfate. Imwe mu mbogamizi zikomeye za urwego rwa 3CR12 ni uko ubuso bw’ibikoresho buhindukamo ingese iyo bihuye n’ibidukikije ibyo ari byo byose. Niyo mpamvu ibikoresho bigarukira gusa ku mitako.
Icyuma kidafunze cya 3CR12 gifite ubushobozi bwo kurwanya ihumana hagati ya dogere selisiyusi 600 na 750 mu kirere kirimo umwuka no hagati ya dogere selisiyusi 450 na 600 mu kirere gifite umuvuduko mwinshi. Ibikoresho birakomera iyo bimara igihe kirekire bihura n'ubushyuhe buri hagati ya dogere selisiyusi 450 na 550. Ariko, ibyo bikoresho ntibitakaza ubushobozi bwabyo bwo kurwanya ikwirakwira muri ubu bushyuhe.
Icyuma cya Grade 3CR12 gishyirwa ku bushyuhe bwa 700 kugeza kuri 750°C, kigabanyijemo ibice bya 25mm, buri gice kikarobeshwa mu gihe cy'amasaha 1.5. Hanyuma reka ibikoresho bikonje. Hagomba kwitonderwa kugira ngo hirindwe gukomera mu gihe cyo gutunganya ubushyuhe. Imiterere ya mashini n'ubudahangarwa bw'ubu bwoko bw'ibi bigirwaho ingaruka no kuzimya.
Uburyo bwo gusudira bukoreshwa mu byuma bitagira umushongi bya austenitic bushobora gukoreshwa ku byuma bitagira umushongi bya 3CR12. Tekereza ku ikoranabuhanga rikoresha ubushyuhe buke nka GMAW (MIG) na GTAW (TIG). Mu gusudira, insinga zuzuza urwego rwa 309 zemewe mbere ko zikurikiza AS 1554.6 nizo zikundwa. Ariko, insinga za 308L, 316L, 309Mo na 309L nazo zikoreshwa mu bihe byinshi. Ihinduka ry'ibara ry'ibicuruzwa byasutswe rishobora gukurwaho hakoreshejwe gaze cyangwa tekiniki nko gusukura no gusya.
Ububasha bwo gukora icyuma kitagira umugese cya 3CR12 ni hafi 60% by'icyuma cyoroshye. Igipimo cyo gukora icyuma cyacyo kiri hasi ugereranyije n'icy'icyuma cya austenitic, bityo nta buryo bwihariye bwo gukora icyuma bukenewe.
Impapuro z'icyuma cya 3CR12 ziboneka mu irangi risanzwe rya Hot Rolled Annealed and Pickled (HRAP), naho imigozi iboneka mu irangi rya 2B cyangwa 2D. Irangi ry'umukara rishobora kandi gukorwa mu bikoresho bishyushye, bigasiga ubuso bw'umukara bwa oxidized ku cyuma. Irangi ry'umukara rya 3CR12 rirwanya ingese neza kandi ridafite uburyaryate bwinshi, bityo rikaba rikwiriye gukoreshwa mu buryo butandukanye.
Mwaramutse Richard, nishimiye kuguha ingano iyo ari yo yose ya 3Cr12. Dutanga ibikoresho biri mu kirango cya Cromgard C12. Nyamuneka mpamagare kuri 719-597-2423. Jane Robinson.
Ibitekerezo byatanzwe hano ni iby'umwanditsi kandi ntabwo ari ngombwa ko bigaragaza ibitekerezo n'ibitekerezo bya AZoM.com.
Muri Advanced Materials muri Kamena 2022, AZoM yaganiriye na Ben Melrose wo muri International Syalons ku bijyanye n'isoko ry'ibikoresho bigezweho, Inganda 4.0, n'intambwe yo kugera kuri zeru.
