Dab tsi yog cov khoom ntawm Q235 steel?
Q235 steelyog ib hom carbon structural steel nrog zoo weldability, plasticity, thiab formability. Nws lub zog tensile yog 370-500 MPa, thiab nws lub zog tawm los yog kwv yees li 235 MPa. Nws muaj kev ua tau zoo tshaj plaws thiab kev lag luam, yog li nws tau siv dav hauv kev tsim kho, engineering qauv, thiab ua cov khoom siv rau ntau cov khoom ua tiav.
ERW galvanized yeeb nkab yog dab tsi?
ERW galvanized yeeb nkabyog ib hom steel yeeb nkab uas tsim los ntawm welding ca hlau strips rau hauv ib tug tubular zoo (ERW), thiab ces galvanizing cov yeeb nkab phab ntsa los tiv thaiv corrosion.
Puas yog galvanized yeeb nkab carbon steel?
Yog lawm,galvanized yeeb nkabyog ib hom carbon steel yeeb nkab nrog zinc txheej los txhim kho corrosion kuj. Cov khoom siv hauv paus yog carbon steel, thiab cov txheej txheem galvanizing yuav immersing cov yeeb nkab steel hauv molten zinc los yog siv cov txheej txheem electrolytic los tsim cov zinc txheej.
Hom hlau twg yog Q235 steel sib npaug?
