Product Description

Hot Work Die Steel Plate 1.2344 H13 SKD61
 

1. Definition
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.
