Dab tsi yog cov khoom siv weldability ntawm S235JR cov qauv steel kav?
Vim lawv cov ntsiab lus qis carbon,S235JR cov qauv hlau kavmuaj zoo weldability. Yog li ntawd, txawm tias nyias nyias tuaj yeem welded siv tag nrho cov txheej txheem vuam yam tsis muaj preheating.
Dab tsi yog qhov tseem ceeb ntawm cov qauv zoo ntawm cov kav hlau square piv rau cov kav hlau puag ncig?
Lub ntsiab yam ntxwv zoo ntawmrectangular steel kavdag nyob rau hauv lawv superior dabtsi yog khoov zog thiab torsional nruj. Lawv lub tiaj tiaj thiab cov npoo ua rau lawv muaj kev ruaj ntseg dua thiab muaj zog nyob rau hauv cov lus qhia tshwj xeeb, ua rau lawv zoo tagnrho rau cov qauv thav duab, cov kab hauv tsev, thiab cov txuas hniav uas thauj khoom -cov kabmob muaj peev xwm thiab qhov nruj yog qhov tseem ceeb.
Txoj kev kho saum npoo dab tsi yog siv los tiv thaiv xeb ntawm S235JR steel?
Feem ntau xeb-kev tiv thaiv nto kev kho mob rauS235JR hlausuav nrog galvanizing, pleev xim, hmoov txheej, thiab xeb-cov roj tiv thaiv. Kub-dip galvanizing tsim ib txheej txheej zinc tiv thaiv, pleev xim thiab hmoov txheej ua kom muaj kev tiv thaiv kev tiv thaiv, thaum xeb-cov roj tiv thaiv yog ib qho kev daws teeb meem ib ntus tsim nyog rau kev khaws cia thiab kev thauj mus los.
Yuav ua li cas corrosion resistant yog S235JR cov qauv hlau kav?
