Features of KDA1
1. Superior heat-check resistance
Hard to crack in comparison with the SKD61, and has a finer structure.
Has superior heat-check resistance equivalent to the KDA1S and offers longer service life.
2. Superior tenacity
80% or more higher tenacity than the SKD61 (in the T direction).
Good tenacity equivalent to the KDA1S.
3. Superior heat-softening resistance
Twice as high heat-softening resistance as the SKD61 maintains high hardness for a long time.
