BS EN 10210 S355J0H, icyuma nimero 1.0547, ni igice cy'icyuma gifite ubushyuhe kandi gishobora kuba umuyoboro w'icyuma udasobekeranye cyangwa uhujwe, gikoreshwa cyane mu nyubako zisaba imbaraga nyinshi n'ubukomere bwiza, nk'inkingi nini z'inyubako n'ibiraro.
Ibikoresho bya S355J0H bifite imiterere ya mekanike ku buryo imbaraga nkeya zo gutanga umusaruro ari 355MPa iyo ubugari bw'urukuta butarenze mm 16 kandi buhuye n'imbaraga nkeya za 27J kuri 0℃.
BS EN 10210 irimo imiterere itandukanye y’ibice, nk’uruziga, kare, uruziga rw’impande, cyangwa uruziga rw’inyuma, Botop Steel yihariye mu gukora imiyoboro y’icyuma imeze nk’uruziga mu bunini butandukanye, iguha ibikoresho by’icyuma byiza kandi byujuje ibisabwa hamwe n’igurishwa ry’uruganda mu buryo butaziguye n’igiciro gishimishije.
Icyitonderwa: Ibisabwa byose muri iyi nyandiko bireba kandi EN 10210.
Ubugari bw'urukuta ≤120mm.
Izengurutse (HFCHS): Ingufu zo hanze kugeza kuri mm 2500;
Kare (HFRHS): Ingano zo hanze kugeza kuri mm 800 x mm 800;
Ingano y'urukiramende (HFRHS): Ingano zo hanze kugeza kuri mm 750 x mm 500;
Ingano z'inyuma (Eriptical) (HFEHS): Ingano z'inyuma zigera kuri mm 500 x mm 250.

Imiterere y'ibikoresho muri BS EN 10210 ishingiye ku mbaraga nkeya z'umusaruro wazo ku bugari bw'urukuta rwa 16mm n'imiterere y'ingaruka ku bushyuhe bwihariye. Imbaraga z'umusaruro, imbaraga zo gukurura, no kurekura kwa BS EN 10210 S355J0H bigabanuka uko ubugari bw'urukuta bwiyongera.
BS EN 10210 yemerera gukora hakoreshejwe uburyo butandukanye bwo gukora, busanzwe burimo uburyo bwo gusudira butarimo imigozi, LSAW, SSAW, na ERW.
Hasi hari ubwoko butandukanye bw'ibicuruzwa bikoreshwa mu gutunganya ibintu bisanzwe.
Dukurikije igereranya ryavuzwe haruguru, bigaragara ko imiyoboro y'icyuma idakora ifite akarusho gakomeye mu gukora imiyoboro y'icyuma ifite inkuta nini, cyane cyane imiyoboro y'icyuma ifite umurambararo muto, ariko ingano yayo izaba nke. Niba ukeneye gukora imiyoboro y'icyuma ifite umurambararo urenga mm 660, bizagorana cyane.
Umuyoboro w'umukara
Ibi bivuga umuyoboro w'icyuma udafite uburyo bwo gutunganya ubuso.
Irangi ry'agateganyo ririnda
Kugira ngo hirindwe ingese y'imiyoboro y'icyuma mu gihe cyo kubika, gutwara, cyangwa gushyiraho, uburyo busanzwe ni ugusiga irangi cyangwa ruvani ku buso bw'umuyoboro.
Ipantaro irwanya ingese
Hari ubwoko bwinshi bw'imyambaro irinda kwangirika, harimo irangi, FBE,3LPE, na galvanized. Buri bwoko bw'ipamba bufite imiterere yihariye n'ibidukikije bifatika. Ingasi n'ingese bishobora kwirindwa neza hakoreshejwe ipamba rikwiye rirwanya ingese ku buso bw'icyuma.
EN 10210 Irangi rishyushye rikozwe mu cyuma rigomba kubahiriza ibisabwa na EN ISO 1461.
Ubushobozi bwo kwihanganira imiterere, imiterere n'ubunini

Uburebure bw'umugozi wo gusudira urwanya ubusanzwe ntiburenza cyane ubuso bw'umuyoboro, kandi mu gihe cyo kuwukora, umugozi wo gusudira uratunganywa ku buryo uba uhujwe n'ubuso bw'umuyoboro kandi ntugaragare neza.
BS EN 10210 S355J0H ikoreshwa cyane mu nyubako, mu gukora imashini, imiyoboro y'ubwikorezi, mu bwubatsi bw'ibikorwaremezo, amato, no mu buhanga bwo mu mazi. Ingufu zayo nyinshi n'ubukomere bwayo bwiza bituma iba nziza cyane mu mishinga nk'ibiraro, inyubako ndende, inganda, inganda, imiyoboro y'amazi, imiyoboro y'amazi ya peteroli na gaze, n'iminara y'amashanyarazi aturuka mu muyaga.

Kuva yashingwa mu 2014, Botop Steel yabaye ikigo gikomeye mu kugurisha imiyoboro y'icyuma cya karuboni mu majyaruguru y'Ubushinwa, kizwiho gutanga serivisi nziza, ibicuruzwa byiza, n'ibisubizo byuzuye.
Iyi kompanyi itanga imiyoboro itandukanye y’icyuma cya karuboni n’ibindi bifitanye isano, birimo imiyoboro y’icyuma idakora neza, ERW, LSAW, na SSAW, ndetse n’urutonde rwuzuye rw’imiyoboro n’ibice bifunganye. Ibicuruzwa byayo byihariye birimo kandi alloys nziza n’ibyuma bitarangirika bya austenitic, byakozwe kugira ngo bihuze n’ibikenewe mu mishinga itandukanye y’imiyoboro.
Ibindi bicuruzwa bifitanye isano:
Umuyoboro w'icyuma wa BS EN10210 S275J0H LSAW(JCOE)
Umuyoboro w'icyuma wa ERW wubatswe mu nyubako ya EN10210 S355J2H
Twandikire kugira ngo ubone ibiciro n'inama ku mushinga wawe ku buntu.
