Product Description
Q390B qis- alloy siab- lub zog steel phaj tsuas yog xav tau kom ua tau raws li tus qauv rau kev cuam tshuam ntawm chav tsev kub. Nws cov txheej txheem thiab vuam yog qhov yooj yim, uas tuaj yeem txo cov nqi tsim khoom thiab kev yuav khoom ntawm cov khoom thauj -cov kabmob steel qauv ntawm chav tsev kub. Nws yog cov khoom siv tseem ceeb rau sab hauv tsev thiab cov khoom siv ua haujlwm me me xws li lub Hoobkas thav duab, engineering machinery bases, thiab cov thawv txhawb nqa.
