Product Description

DIN 1.2842_AISI O2 Cold Work Tool Steel

 

It's medium alloyed cold work steel, with high hardening capacity, good compressive strength.

 

Equivalent Grade:

Standard	Grade
AISI/SAE	O2
W.Nr/DIN	1.2842

 

Typical Chemical Composition (%)

C	Si	Mn	Cr	V
0.85-0.95	0.10-0.40	1.90-2.10	0.20-0.50	0.05-0.15

 

Heat Treatment:

Annealing: 700 to 730ºC, slow cooling in furnace (10-20ºC/hr), down to approx. 600ºC, cooling in air. Hardness after annealing: max. 230HB.

Stress relieving: approx. 650ºC, slow cooling in furnace. Hold in neutral atmosphere for 1 to 2hours.

Hardening: 790 to 820ºC, oil. Quenching: oil. Hardness obtainable, 60 to 64 HRC.

Tempering: Slowly heating to tempering temperature right after hardening. Recommended to temper 2 or 3 times to increase toughness.

Tempering ºC	100	200	300	400	500
HRC	64	62	57	52	46

* Hardening temperature: 800ºC, specimen size: dia25mm

 

Properties:

Oil hardening type cold work steel. Good dimensional stability, edge retaining and toughness. Deep hardening properties can be considered as good for smaller and medium-sized sections.

 

Applications:

Blanking and punching dies for sheet thickness up to 6 mm; small straight and circular shear blades, also for paper and plastics; thread cutting tools; gauges and other measuring tools; cold trimming tools; small inserts for plastic moulds and similar tools.
