S420M qis alloy steel phaj
S420M tsis tshua muaj alloy steel ntawv yog European txheem alloy qauv steel ntawv. S420M alloy steel yog ua los ntawm carbon steel. Txhawm rau txhim kho qhov kev ua tau zoo ntawm cov hlau, ib lossis ob peb lub ntsiab lus alloy ntxiv.
S420M low alloy structural steel yog haum rau hnyav-duty Cheebtsam ntawm welded lug siv nyob rau hauv ib puag ncig thiab tsis kub tej yam kev mob, xws li txuas hniav, sluices, cia tso tsheb hlau luam, dej tank, thiab lwm yam.
