Low Carbon Steel Ball

The most important feature of this material type is the heat-treatment through the hardening of the superficial layer (case hardening), while the internal part of the ball remains soft. These ball offer remarkable savings for all those applications which don’t need the usage of fully hardened chrome steel or high carbon steel balls.
