BOROSTAR belongs to a family of Boron-treated medium-carbon steels developed to improve hardenability during heat treatment.

With hardenability equivalent to that of much higher carbon steels and more expensive low alloy steels, these Boron grades are perfect for applications that require high wear/abrasion resistance. The prime advantage of hot forming steels is their suitability for water quenching, making the process more environment-friendly than that used for conventional carbon steel, with excellent hardening performance during both liquid and gas quenching.
