Avadur® grades meet high standards of hardness and yield strength while maintaining good machinability. Building on the chrome-molybdenum grade 4140, these products can be heat treated to attain a broad range of special hardness, yield strength and tensile strength levels which can even be varied further by subsequent tempering.
There are three variants in Avadur® series that feature additionally impact toughness.
Most popular within Australia is the Avadur® 758(110) HardFIT which has hardness levels HRC 28-36.
