EN 10137 S620Q siab yield zog cov qauv hlau
S620QL cov khoom siv hlau tsis tshua muaj hlau yog lub zog siab zoo cov qauv hlau uas ua tau raws li European tus qauv EN 10025-6.
S620QL siab zog steel muaj cov khoom siv vuam zoo thiab tuaj yeem welded los ntawm ntau txoj kev vuam, xws li phau ntawv arc vuam, roj tiv thaiv vuam (GMAW, GTAW), thiab lwm yam.
S620QL siab zog qis alloy steel phaj tuaj yeem siv rau cov tsev siab siab, cov qauv steel loj, cov kab teeb tseem ceeb thiab kev txhawb nqa ntawm cov choj loj loj, thiab lwm yam.
