* Annealed cov khoom yog ib yam rau cov mob A ntawm ASTM A582.
** Hardened thiab tempered Condition T ntawm ASTM A 582 - Brinell hardness yog teev ntau yam, lwm yam khoom yog ib yam nkaus xwb.
^#Tempering ntawm cov hlau no ntawm qhov kub ntawm 400 txog 580 ° C yuav tsum tau zam vim muaj kev cuam tshuam tsis zoo.
