GR. LC1 Heat treatment process:

Ferrite castings shall be furnished in the normalized and tempered or liquid-quenched and tempered condition. Castings shall be tempered at a minimum of 1100°F [590°C], followed by cooling in air or liquid

Castings shall be allowed to cool below the transformation, range directly after pouring and solidification before they are reheated for normalizing or liquid quenching.
