Vuba aha, umukiriya yaje gusura uruganda S355J2umuyoboro ushongeshejwe, urugendo rwose, abakozi bashinzwe kugurisha basobanuye bihanganye.S355J2HUmuyoboro w'icyuma wa ERW ni umuyoboro w'icyuma wa karuboni-manganese mwiza kandi urwanya ingaruka mbi cyane. Iki gikoresho gikoreshwa cyane mu nyubako nko mu nyubako, ibiraro, imihanda minini, n'indi mishinga y'ubwubatsi.
Imiyoboro y'icyuma ya S355J2H ikorwa hakoreshejwe uburyo bwo gusudira bukoresha amashanyarazi (ERW), bukubiyemo gukora ibyuma birambuye mu miyoboro hanyuma bigasudira imiyoboro. Ibigize imiti y'umuyoboro w'icyuma wa S355J2H ERW birimo karuboni, manganese, silikoni, fosifore, na sulfure, kandi imbaraga nkeya ni 355 N/mm². Umuyoboro kandi ufite imiterere myiza ya mekanike, ufite imbaraga ntarengwa zo gukurura 510-680 N/mm². Ufite ubushobozi bwo gusudira neza kandi ingano yawo ya karuboni nke ifasha kugabanya ibyago byo kwangirika mu gihe cyo gusudira. Imwe mu nyungu z'ingenzi z'umuyoboro w'icyuma wa S355J2H ERW ni ubudahangarwa bwawo bukomeye. Ibi bituma uba ukwiriye gukoreshwa aho imiyoboro ishobora gutwarwa n'imizigo iremereye cyangwa ihindagurika. Byongeye kandi, ingano y'ubugari bw'urukuta rw'umuyoboro n'ubuso bworoshye bw'imbere n'inyuma bigira uruhare mu gutuma imiterere yawo ikomera kandi byoroshye kuyishyiraho. S355J2HUmuyoboro w'icyuma wa ERWiboneka mu bunini n'uburebure butandukanye, bigatuma iba amahitamo menshi mu bikorwa bitandukanye. Ishobora gukoreshwa mu gutwara amazi, imyuka cyangwa ibintu bikomeye, kandi kubera imbaraga zayo nyinshi, ishobora no gukoreshwa mu bikorwa by'ubwubatsi. Muri make, umuyoboro w'icyuma wa S355J2H ERW ni amahitamo yizewe kandi arambye mu bikorwa bitandukanye by'ubwubatsi. Irwanya ingaruka zikomeye, imiterere myiza ya mekanike n'ubushobozi bwayo bwo gukora ibintu bitandukanye bituma ikoreshwa mu bikorwa bitandukanye.
