JIS G 3454ni igipimo ngenderwaho cy’inganda zo mu Buyapani ku miyoboro y’icyuma cya karuboni ku buryo bw’umuvuduko w’amashanyarazi bufite ubushyuhe ntarengwa bwo gukora bwa 350°C. Igipimo ngenderwaho kirimo urwego rubiri:STPG 370naSTPG 410Ikoreshwa ku miyoboro idafite umugozi ikoreshwa n'amashanyarazi (ERW) cyangwa imiyoboro idafite umugozi ifite umurambararo wa mm 10.5 kugeza 660.4 (ni ukuvuga 6A kugeza 650A, cyangwa 1/8B kugeza 26B).
JIS G 3454 Imiyoboro y'icyuma igomba gukorwa hakoreshejwe uburyo bukwiye bwo gukora imiyoboro y'icyuma n'uburyo bwo kurangiza mu mbonerahamwe iri hepfo.

Gukomera
Uburyo bwo gupfunyika bukoreshwa ku miyoboro ifite umurambararo wa 40 A (48.6) cyangwa muto.
Umuyoboro ugomba kunamikwa kuri dogere 90 ku murambararo w'umurambararo w'inyuma inshuro 6. Urukuta rw'umuyoboro rugomba kuba rudafite inenge cyangwa imiturire.
Buri muyoboro w'icyuma ugomba gupimwa umuvuduko wa hydrostatic cyangwa ikizamini kitangiza.

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, harimo imiyoboro y’icyuma idakora neza, ERW, LSAW, na SSAW, ndetse n’urutonde rwuzuye rw’imiyoboro n’ibice by’imiyoboro.
Ibikoresho byayo byihariye birimo kandi aloi nziza n'ibyuma bitagira umugese bya austenitic, byakozwe kugira ngo bihuze n'ibyo imishinga itandukanye y'imiyoboro isaba.
Twandikire, tuzaguha imiyoboro y'icyuma igezweho kandi isanzwe hamwe na serivisi nziza kandi ijyanye n'ubuhanga. Botop yiteguye kugukorera.
