JIS G 3461 umuyoboro w'icyumani umuyoboro udasanzwe (SMLS) cyangwa umuyagankuba wogosha amashanyarazi (ERW) umuyoboro wibyuma bya karubone, ukoreshwa cyane mubyuma no guhanahana ubushyuhe mubisabwa nko kumenya guhanahana ubushyuhe hagati yimbere no hanze yacyo.
STB340ni icyuma cya karubone icyiciro cya JIS G 3461.Ifite imbaraga zingana zingana na 340 MPa nimbaraga ntoya ya 175 MPa.
Nibikoresho byo guhitamo mubikorwa byinshi byinganda kubera imbaraga zabyo nyinshi, guhagarara neza kwubushyuhe, guhuza n'imihindagurikire, kurwanya ruswa ugereranije, gukoresha neza, no gutunganya neza.
JIS G 3461ifite amanota atatu.STB340, STB410, STB510.
STB340: Imbaraga ntarengwa: 340 MPa;Imbaraga nke zitanga umusaruro: 175 MPa.
STB410: Imbaraga ntarengwa: 410 MPa;Imbaraga Ntoya Zitanga: 255 MPa.
STB510:Imbaraga ntarengwa: 510 MPa;Imbaraga Ntoya Zitanga: 295 MPa.
Mubyukuri, ntabwo bigoye kumenya ko icyiciro cya JIS G 3461 cyashyizwe mubikorwa ukurikije imbaraga nkeya zingana zumuyoboro wibyuma.
Mugihe urwego rwibikoresho rwiyongera, imbaraga zabyo hamwe nimbaraga zitanga umusaruro byiyongera bikwiranye, bigatuma ibikoresho bihanganira imitwaro iremereye hamwe nigitutu cyibikorwa byinshi bisaba akazi.
Hanze ya diameter ya 15.9-139.8mm.
Gukoresha mubyuma no guhinduranya ubushyuhe mubisanzwe ntibisaba diameter nini cyane.Imiyoboro ntoya ya diametre yongerera ingufu ubushyuhe kuko ubuso bwuburinganire bwikigereranyo cyo kohereza ubushyuhe buri hejuru.Ibi bifasha guhererekanya ingufu zubushyuhe vuba kandi neza.
Imiyoboro igomba gukorwa kuva iyishe ibyuma.
Guhuza uburyo bwo gukora imiyoboro nuburyo bwo kurangiza.
Muburyo burambuye, barashobora gutondekwa muburyo bukurikira:
Umuyoboro ushyushye utarangwamo ibyuma: SH
Ubukonje burangiye butagira ibyuma: SC
Nkumuriro wamashanyarazi weld wicyuma: EG
Amashanyarazi ashyushye arangije gusudira ibyuma: EH

Hano haribikorwa byumusaruro ushushe-urangije nta nkomyi.
Kubikorwa byo gukora bidafite aho bihuriye, birashobora kugabanywa hafi yimiyoboro yicyuma idafite umurambararo wa diameter irenga 30mm ukoresheje umusaruro ushushe, na 30mm ukoresheje umusaruro ukonje.
Uburyo bwo gusesengura ubushyuhe bugomba gukurikiza ibipimo biri muri JIS G 0320.
Kuvanga ibintu bitari ibyo birashobora kongerwaho kugirango ubone ibintu byihariye.
Iyo ibicuruzwa bisesenguwe, indangagaciro zitandukanya imiterere yimiti yuyoboro igomba kuba yujuje ibyangombwa bisabwa mu mbonerahamwe ya 3 ya JIS G 0321 ku miyoboro y’icyuma idafite imbonerahamwe na Imbonerahamwe ya 2 ya JIS G 0321 ku miyoboro y’icyuma isudira.

Nubwo ibyo bikoresho bishobora kuba bisa mubijyanye nimiterere yimiti nibintu byibanze, uburyo bwihariye bwo gutunganya ubushyuhe no gutunganya bishobora kugira ingaruka kumiterere yibicuruzwa byanyuma.
Kubwibyo, kugereranya birambuye no kugerageza bikwiye gukorwa mugihe uhitamo ibikoresho bihwanye nibikorwa bifatika.
Kuva yashingwa mu 2014, Botop Steel yabaye iyambere mu gutanga imiyoboro ya karubone mu majyaruguru y’Ubushinwa, izwiho serivisi nziza, ibicuruzwa byiza, ndetse n’ibisubizo byuzuye.Isosiyete itanga imiyoboro inyuranye y’ibyuma bya karubone n’ibicuruzwa bifitanye isano na byo, birimo icyuma, ERW, LSAW, hamwe n’icyuma cya SSAW, ndetse n’umurongo wuzuye w’ibikoresho bya flanges na flanges.
Ibicuruzwa byayo bidasanzwe birimo kandi amavuta yo mu rwego rwo hejuru hamwe na austenitis ibyuma bitagira umuyonga, bigenewe guhuza ibyifuzo byimishinga itandukanye.
