H-13 Flat ESR Quality (1.2344) for Aluminium Pressure Die Casting
H-13 ESR is the most refined material with the traditional VD route. The quality of
material increase the toughness, highly increase the micro-cleanness level.
High recommend the use of AISI-H-13 ESR grade for Aluminium Pressure Die Casting & other component subjected to high working temperatures and high pressure strength. H-13 is fully ultrasonic inspected with 100% positive results as per NDT Standards.
H-13 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 the heat cracking, good mechanical characteristics & toughness in hot condition. H13 apears excellent machinability with constant hardness during production activities.
