S690QL yog lub siab -} lub zog, quenched thiab tempered qauv qauv hlau sib xyaw ua ke rauEN 10025-6Cov Qauv. Kev tsim qauvS690QLqhia aYam tsawg kawg nkaus los lub zog ntawm 690 MPAthiab lub tensile lub zog ntawm kwv yees li740-940 MPA, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau cov khoom lag luam siab {{bearing} cov kabmob muaj peev xwm.
Cov qib no muaj kev ua haujlwm zoo tshaj plawsmuaj, tus nqi - ua tau zoo, thiab kev ua tau zoo, suav nrog:
Siab dua cov khoom siv: Cov qoob loo siab thiab lub zog tensile ua kom muaj cov qauv sib zog tsis muaj kev nyab xeeb.
Zoo Weldability: Haum rau cov kev tsim muaj welded ua kom zoo thaum siv preheating kom zoo thiab vuam.
Siab heev: Tswj hwm kev cuam tshuam zoo heev txawm tias kub tsawg.
