Virat Special Steels H13

H13 tool steel is the most popular steel grade for various Industries. The main features of high alloyed Cr-Mo-V Hot Work tool steel is high wear resistance to thermal shock and to heat cracking, good mechanical characteristics & toughness in hot condition.H13 appears excellent machinability with constant hardness during production activities.
The equivalent steel grade H-13 / SKD61 / AISI H13 normally available in the annealed condition but in some specific applications, we provide Pre-Hard H13 with its standard hardness 460-500 BHN.
Utilized for ejector pins, apparatus holders and shrink fit chucks.


ESR is the most refined material with the traditional VD route. The quality of material increase the toughness, highly increase the micro- cleanness level.
Highly recommend the use of AISI-H13 ESR grade for Aluminum Pressure Die Casting & other component subjected to high working temperatures and high pressure strength. H13 is fully ultrasonic inspected with 100% positive results as per NDT standards.

H13 Steel Properties

High hot-wear resistance and hot tensile strength as well as good toughness, thermal conductivity and insusceptibility to hotcracking. Can be water-cooled to a limited extent.
