Quard get its high hardness and strength through a precise water quenching process.
The hardness is mainly controlled by the carbon content and by using accurate alloy compositions the scatter in hardness and other properties can be kept to a minimun.
The production process of Quard produces a lath type of martensitic structure of high hardness, strength and toughness, granting 100% through thickness hardening.
