Product details

1.2311 is a pre hardened high tensile tool steel which offers ready machineability in the hardened and tempered condition, therefore does not always require further heat treatment . This eliminates the risks, cost, and waiting time of heat treatment and avoids the associated possibility of distortion or even cracking. Subsequent 1.2311 component modifications can easily be carried out.


Forging:
Heat slowly and uniformly to 1050°C. Do not forge below 930°C. After forging cool slowly.
 

Annealing:
1.2311 should always be annealed after forging and before rehardening. Heat uniformly to 770/790°C.
Soak well and cool slowly in the furnace.
 

Hardening:
Heat uniformly to 840/870°C until heated through. Quench in oil.
 

Tempering:
Heat uniformly the 1.2311 tool thoroughly at the selected tempering temperatures and hold at heat for one hour per 25 millimetre of total thickness.
