S690QL siab zog steel phaj

Vim cov ntaub ntawv muaj zog muaj zog, siv S690QL yuav txhawb nqa leaner tsim qauv nrog rau kev muaj peev xwm ntxiv thiab lub zog ua haujlwm.
Cov ntsiab lus ntawm S690QL tau piav qhia hauv qab no.
S690QL - Qib Qib
Qib kev xaiv ntawm S690QL yog cov hauv qab no:
S = Structural Steel
690 = Yam tsawg kawg nkaus tawm lub zog (MPa)
Q = Quenching & Tempering
L = Qhov ntsuas qhov ntsuas kub tsis tshua muaj siab toughness
