Kev tsim kho steel kav yog cov qauv carbon steel raj siv nyob rau hauv lub tsev thiab infrastructure tej yaam num, muab siab zog, toughness, thiab load- bearing muaj peev xwm nrog tensile zog feem ntau ntawm 400-550 MPa. Lawv tau siv dav hauv scaffolding, steel moj khaum, thiab kev txhawb nqa cov qauv rau kev txhim kho kev txhim kho thiab ruaj khov.
