ST52 ST52-3 S355JR S355J0 Chitsulo chokhazikika chachitsulo chozungulira
St52 ndi ya chitsulo chochepa cha alloy champhamvu kwambiri, Mogwirizana ndi China ndi zinthu ziti zomwe st52 ndizofanana ndi Q345B, kapena 16mn ndi Q345D.Gawo lofanana lachitsulo ndi ST52-3 S355JR S355J0.
The zitsulo bala akhala ntchito mitundu yonse ya madera monga ndege, zamlengalenga, kuyenda, mphamvu nyukiliya, makampani mankhwala, zidziwitso zamagetsi, kupanga makina, petrochemical, magalimoto, chida ndi mita, Kulankhulana, zoyendera, ndi zida zachipatala, etc.
