Boron-alloyed case hardening steels
Boron-alloyed case hardening steels are low-carbon alloy steels designed to develop a hard surface with a tougher core after case hardening. Their boron addition improves hardenability, while the alloying composition supports the production of durable gears, shafts and other wear-prone components.
