    1.Hardness Test
    Thaum yuav tsum muaj kev txwv hardness, cov chaw tsim khoom yuav tsum tau sab laj.Tej hardnesses yog teev nyob rau hauv Table .Thaum tau teev tseg, qhov hardness test yuav tsum tau ua nyob rau hauv 1% ntawm cov hlab.

    2. Kev Ntsuas Kev Nyuaj Siab
    Thaum cov khoom tensile xav tau, cov chaw tsim khoom yuav tsum tau sab laj.Cov khoom tensile zoo rau qee cov qib ntau dua thiab cov thermal tej yam kev mob tau teev nyob rau hauv cov lus.

    3.Nondestructive Tests
    Muaj ntau hom kev kuaj ultrasonic lossis electromagnetic nondestructive.Qhov kev xeem yuav tsum tau siv thiab kev soj ntsuam txwv yuav tsum tau tsim los ntawm cov chaw tsim khoom thiab cov neeg yuav khoom pom zoo.

    4.Flaring Test
    Thaum muaj cov kev cai tshwj xeeb rau kev huv huv steel, cov txheej txheem ntawm kev sim thiab kev txwv ntawm kev lees txais yuav tsum raug tsim los ntawm cov chaw tsim khoom thiab cov neeg yuav khoom pom zoo.
