1.2343 / 1.2343 ESU Hot-work steel

Designation

DIN:X 37 CrMoV 5-1
AFNOR:Z 38 CDV 5
UNI:X 37 CrMoV 5-1 KU
AISI:H11 / H11 ESR

Indicatory analysis:

C0.38
Si1.00
Mn0.40
Cr5.30
Mo1.20
V0.40

Strength:

max. 230 HB
(≈ max. 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

High temperature strength chart:


TechnicalTip:
  • susceptible to corrosion; during maching, continuous corrosion protection has to be ensured (especially during wire EDM)
  • 1.2343 ESR is highly suitable for mirror polishing
