|---|---|---|---|---|---|
| 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
