DESIGNATION

GB DIN AFNOR UNI AISI Japan
4Cr5MoSiV1 X38CrMoV5-1 Z38CDV5 X37CrMoV5-1 KU H11 SKD6

STRENGTH:

≈ 780 N/mm² 

THERMAL CONDUCTIVITY AT 200 °C:

27 W/m K 

 
CHARACTER:

high-alloy hot-work steel with high toughness and heat resistance, hot cracks resistance and good thermal conductivity; for very high requirements available in grade *ESR (Electro-Slag Remelted)

APPLICATION:

molding plates and inserts for plastic injection mold tools; *ESR for applications for die casting (Al, Mg, Zn)

 
TREATMENT BY

highly suitable:
Polishing

very easily feasible (graining):
Etching
EDM:
in the hardened and tempered condition, treat again for stress relief about 20 °C below the last tempering temperature
Nitriding:
increases the wear resistance and prevents the bonding of casting material
Hard chroming: 
in special cases

 
HEAT TREATMENT:

Annealing:
750 to 800 °C, about 4 to 5 hours slow controlled cooling of 10 to 20 °C per hour to about 600 °C; further cooling in air, max. 205 HB

Hardening: 
1000 to 1040 °C
15 to 30 minutes keeping curing temperature
quenching in water/oil/air
obtainable hardness: 50−56 HRC

Nitriding:
Before nitriding stress-relief annealing is recommended at 550 °C. (Meusburger standard) 
A treatment at 525 °C in ammonia gas results in a surface hardness of approx. 55 HRC

Tempering: 
slow heating to tempering temperature immediately after hardening; minimum time in furnace: 1 hour per 20 mm part thickness; repeated tempering is recommended
