1.2344 H13 Alloy Hot Work DIE Steel Flat Bar With Length
3000-6000mm BLACK SURFACE
1.2344/H13/SKD61 steel is a pressure resistant hot work die steel.
The steel is remelted by electroslag, uniform in material, good in
hardenability, excellent in machinability and polishing
performance, high toughness and plasticity, good high and low
temperature wear resistance, and high temperature fatigue and heat
resistance.
