Q420 Intangiriro
Icyuma cya Q420 nicyiciro cyicyuma cyo mubushinwa cya Low Alloy High Strength Structural Steel, Imbaraga Zitanga ni 420 MPa, ibipimo bipimishwa hamwe nibyuma bya diametre 16mm cyangwa ibyuma, naho imbaraga zingana ni 520-680 Mpa, ubucucike bwibintu ni 7,85 g / / cm3. Ukurikije GB / T 1591-2008, Q420 ifite urwego 5 rwiza: Q420A, Q420B, Q420C, Q420D na Q420E. Kuri Q420 ibyuma bihwanye, ibigize imiti nibikoresho bya mashini, nyamuneka reba imbonerahamwe iri munsi yibirimo.
Ibiranga n'imikoreshereze
Q420 ibyuma bifite imbaraga nyinshi, cyane cyane mubisanzwe cyangwa bisanzwe bisanzwe hiyongereyeho imiterere yubushyuhe, hamwe nibikoresho byuzuye byubukanishi, birashobora gukoreshwa mumato manini, ibiraro, ibikoresho bya sitasiyo yamashanyarazi, amashyanyarazi aciriritse kandi yumuvuduko mwinshi, ubwato bwumuvuduko mwinshi, imashini zizamura, imashini zicukura na ibindi binini binini byo gusudira.
