MICROFINE STEEL HOT WORK TOOL STEEL KDA1S KDA1S Heat treatment and Heat Softening Resistance Characteristic of KDA1S KDA1S is a new type of steel for die-casting that has the same basic functions of the KDA1 and features superior durability and cost-reduction performance. 1) Heat-check Resistance  Hard to crack in comparison with the SKD61, and has a finer structure.  Has superior heat-check resistance equivalent to the KDA1 and offers a longer service life. 2) A Superior Tenacity  80% or more higher tenacity than the SKD61 (in the T direction). 3) Heat-softening Resistance  Heat-softening resistance is twice better than SKD61, canmaintain high hardness for long time.
