Virat Special Steels AISI H13

AISI-H13 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. AISI-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 2344 with its standard hardness 460-500 BHN. AISI-H13 is the superior steel grade than AISI-H13 / H11 to get better performance of dies.
Utilized for ejector pins, apparatus holders and shrink fit chucks.

AISI-H13 ESR

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. DIN 2344 is fully ultrasonic inspected with 100% positive results as per NDT standards.

AISI 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.
