Product Details
H13 1.2344 SKD61 Tool Steel Plate for Hot Work Die With Thickness
130-280mm
Die-casting mould for aluminum, extrusion mould, and thin-wall
plastics mould.
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.
