kwangirika kwikirere gutura icyuma cyubatswe gikoreshwa cyane mukubaka ibikoresho byoherezwa hamwe n’ibikoresho byo hanze, nka gahunda yo kubika imyanda, Ibihe by’ikirere, ibikoresho by’ibikoresho, ibikoresho by’amahugurwa n'ibindi.
Ibisobanuro:
Umubyimba: 3mm - 150mm
Ubugari: 30mm - 4000mm
Uburebure: 1000mm - 12000mm

Imbaraga zingana cyane ikirere cyicyuma Q415NH hamwe nimbaraga zingana muri 520-680 Mpa, ubunini bungana, imbaraga zumusaruro zigomba kuba hejuru ya 415Mpa mugihe inzogera ari 16mm. Ukurikije ubushyuhe butandukanye, ubushyuhe bwa Q415NH burashobora kuba Q415NHA, Q415NHB, Q415NHC,
Q415NHD , Q415NHE。 Q415NHA isaba ikigereranyo cyubushyuhe buke bwa dogere selisiyusi 40, kandi Q415NHA ntisaba ikizamini cyingaruka.
