Tiv thaiv cov ntsia hlau los ntawm xeb tuaj yeem yog cov hauv qab no:
1, muaj pes tsawg leeg ntawm cov hlau los hloov cov qauv hauv cov hlau.Piv txwv li, chromium, npib tsib xee thiab lwm yam hlau ntxiv rau cov hlau zoo tib yam uas ua los ntawm cov hlau tsis muaj steel, nws ua rau cov xeb kuj ntawm cov khoom hlau zoo heev.
2,Npog lub npoo ntawm cov khoom hlau nrog cov txheej txheem tiv thaiv yog ib txoj hauv kev zoo tshaj plaws los tiv thaiv cov khoom hlau los ntawm xeb.Nyob ntawm seb muaj pes tsawg leeg ntawm cov txheej txheem tiv thaiv, nws tuaj yeem muab faib ua pawg hauv qab no:
