Z 35 CD 17.S
UNI: -
AISI:
≈ 422 + S
CHEMICAL COMPOSITION:
化學成份：
C 0.33
Si 0.30
Mn 0.80
Cr 16.00
S 0.06
Ni 0.30
STRENGTH:
≈ 1080 N/mm?
THERMAL CONDUCTIVITY AT 100 °C:
18 W/m K
CHARACTER:
corrosion resistant, pre-toughened tool steel with good machinability due to Sulphur additive
APPLICATION:
plates for corrosion resistant mold bases and die sets;
molds for corrosive plastics; the expense for protection and care of mold tools is reduced thanks to increased corrosion resistance; not suitable for mold inserts
TREATMENT BY
unusual:
Polishing, etching, EDM, nitriding, hard chroming
HEAT TREATMENT:
Usually no heat treatment is required
Soft annealing:
850 to 880 °C for about 2 to 5 hours
slow controlled cooling, further cooling in air, annealing hardness max. 240 HB
Hardening:
1000 to 1030 °C
keeping curing temperature for 30 minutes
quenching in oil is preferable
obtainable hardness: 48 HRC
Tempering:
slow heating to tempering temperature immediately after hardening;
minimum time in furnace: 2 hour per 20 mm part thickness;
tempering twice is recommended
