SK105(SK3) T11 high carbon steel coil

SK105(SK3) steel is a high carbon steel with a carbon content of more than 1.0%. The advantages of SK3 steel are excellent wear resistance, good machinability, easy source, but low hardenability and large quenching deformation. Because SK3 steel contains few alloying elements, has low tempering resistance and shallow hardened layer, its load-bearing capacity is low.
