Hot Work Steel 1.***3 Flat Bar Features:
1.***3 is air hardening hot work die steel, the same as U. S. H*1
steel, its performance and service life are higher than 3Cr2W8V
steel. Has a high hardenability, good overall performance under the
middle temperature, small deformation when heat treatment, good
resistance to thermal fatigue performance. Is also Alloy Tool
Steel, better adapted to water forced cooling, used for extrusion
dies, the life is closely related with extruded materials and
extrusion ratio. Supply Condition: Hardness
