HEAT TREATMENT

Hardening -

Heat uniformly to 780/820 C depending on bulk. Equalise at temperature, then oil quench to hand warmth. Temper immediately.

The 'interrupted quench' method of hardening is recommended as a means of minimising the possibility of stress cracking or excessive distortion developing during oil quenching.

This involves quenching from the standard hardening temperature into a salt bath held at 180/200 C, equalising at this temperature, & then air cooling to room temperature.

After boiling off the adherent salt, tempering is carried out in the normal way.

Tempering -

Temper as soon as possible after hardening, allowing at least 11/2 hours at temperature.

In practice, tempering is normally carried out in the range 150-220 C.

Applications

• Gauges
• Blanking & forming dies
• Guide plates
• Cams
• Templates
• Shear blades
• Punches
• Slitting cutters
• Press tools
• Machine wear parts etc.

Further processing of this material could lead to exposure to substances, which may present a health hazard.

Therefore effective, local dust / fume extraction must be used.

All Ground Flat Stock is 18" in length.
