AFCEN Z6 CNNb 18-11 Heat Treatments

Final heat treatment for mechanical properties shall consist of solution heat treatment at a temperature between 1050°C and 1150°C.
Final heat treatment for mechanical properties shall consist of solution heat treatment at a temperature between 1050°C and 1150°C.
There are three distinct cases:
a) Plates ≤ 3 mm thick finished by cold rolling
These plates are delivered after cold-rolling, either solution heat-treated, pickled and passivated, or solution heat-treated, pickled, passivated and work-hardened. Sheets and strip may be delivered on spools.
b) Plates > 3 mm thick finished by cold-rolling
These plates shall be delivered after cold-rolling. They shall be solution heat treated pickled and passivated. If work-hardening treatment is necessary, it shall be subject to approval.
c) Plates > 3 mm thick hot-rolled
These plates shall be delivered after hot-rolling. They shall be solution heat treated, pickled and passivated.
