1.2842 Steel for through hardening

Designation

DIN:90 MnCrV 8
AFNOR:90 MV 8
UNI:90 MnVCr 8 KU
AISI:≈ O2

Chemical composition:

C0.90
Si0.20
Mn2.00
Cr0.40
V0.10

Strength:

max. 230 HB
(≈ max. 780 N/mm²)

Thermal conductivity at 100 °C:

33 W/m K


Character:

steel for through-hardening with good machinability and high wear resistance; low warping and high dimensional stability; with high toughness and through hardenability (uniform hardness for cross sections 40 mm)

Application:

cavity plates and inserts exposed to abrasive stress; cutting punches; wear plates, cutting dies and guiding plates; guiding rails


Treatment by

unusual:
Polishing, etching, nitriding » 1.2379

is possible:
EDM, hard chroming


Heat treatment:

Soft annealing:
680 to 720 °C for about 2 to 5 hours; slow controlled cooling of 10 to 20 °C per hour to about 600 °C; further cooling in air, max. 220 HB

Hardening:
790 to 820 °C
Quenching in oil/hot bath
Obtainable hardness: 63-65 HRC

Tempering:
slow heating (to avoid forming of cracks) to tempering temperature immediately after hardening; tempering twice with intermediate cooling down to 20 °C increases the steel's toughness

max. obtainable hardness after tempering: 58−60 HRC

Annealing graph:


Technical tip:
  • Steel grade 1.2510 is an adequate alternative with regards to its properties, machinability and dimensional stability after heat treatment
