SS400 yog ib qho ntawm feem ntau siv kub dov cov qauv hlau qauv steel, peb tuaj yeem siv cov thawv hlau uas muaj peev xwm siv los ua cov thawv dej uas muaj peev xwm ua tau cov dej hiav txwv.
SS400steel Phaj Ntawv yog ib hom hlau rau cov qauv dav, thiab nws lub ntsej muag zoo li cov khoom siv hluav taws xob, txawm tias yog cov qauv kub, txawm tias cov teeb meem ua ke nrog nws cov khoom siv zoo.
Qhov kev qhia tshwj xeeb ntawm SS400 steel phaj npog cov roj txheem hlau qauv, cov hlau, thiab kev tsim kho ob tog, lossis cov vaj tse, thiab rau cov qauv kev ua haujlwm dav dav. Kev tshuaj ntsuam cua sov yuav tsum tau siv los txiav txim siab cov tshuaj lom neeg yuav tsum muaj rau cov pa roj carbon, manganese, phosphorus, sulfur, silicon, thiab tooj. Lub zog tensile, tawm tsam lub zog siv kev ntsuas nro thiab yuav tsum ua raws li lub zog tensile.
