Dab tsi yog cov qauv tseem ceeb rau Q355 steel coils siv hauv kev lag luam tsheb?
Lawv ua raws li GB / T 1591-2018 thiab tseem ua tau raws li cov qauv kev lag luam tsheb (xws li QC / T 518), tsom mus rau kev ntsuas cov khoom muaj zog, lub zog tensile, cuam tshuam lub zog, thiab weldability.
Yuav ua li cas xaiv qhov tsim nyog Q355 steel kauj qib raws li hom tsheb?
Rau cov neeg caij tsheb / lub teeb tsheb thauj khoom hauv thaj chaw kub ib txwm, xaiv Q355B; rau kev lag luam tsheb hauv cheeb tsam txias heev (hauv qab -20 degree), xaiv Q355D; rau cov tsheb nyob rau hauv cheeb tsam txias heev (-40 degree), xaiv Q355E.
Yuav ua li cas lub thickness / specifications ntawm Q355 steel coils phim automotive Cheebtsam?
6-16mm tuab coils yog siv rau chassis beams; 3-8mm rau chassis reinforcements; thiab 1.5-5mm rau lub cev reinforcements, txuam specifications raws li lub load-bearing yuav tsum tau ntawm lub Cheebtsam.
Dab tsi yog qhov kev sib tham ntawm Q355 steel coils thiab thoob ntiaj teb automotive steel qib? Ua raws li European tus qauv S355JR / J0 / J2 thiab Asmeskas tus qauv A572 Gr50, nws cov kev ua tau zoo sib xws thiab nws tuaj yeem siv rau kev tsim khoom xa tawm tsheb.
Dab tsi yog qhov kev thov yav tom ntej ntawm Q355 steel coils hauv kev lag luam tsheb?
Nrog rau kev nce ntxiv ntawm cov qauv hnyav thiab kev nyab xeeb hauv tsheb, Q355 steel coils (tshwj xeeb tshaj yog huab cua- tiv taus thiab siab - hom zog) yuav nthuav dav lawv daim ntawv thov hauv cov qauv ntawm cov tsheb lag luam thiab cov tsheb tshiab, hloov ntau dua - lub zog steel thiab qee cov hlau alloy.
