PROPRIETARY CRUCIBLE 420 Heat Treatments
- Forged: Should be forged at 1950 to 2050°F and finished not lower than 1750°F. Annealed: Annealed for maximum softness by a thorough soaking at 1600°F for six hours, followed by a furnace cool. This grade can be cycle annealed by heating to 1600°F, holding two hours, cooling to 1300°F, and holding four hours. The steel may then be cooled in air if desired. Hardened and tempered: Hardened can be for maximum hardness by oil quenching from 1800 to 1900°F. Large sections should be preheated at about 1250°F. It is desirable to avoid tempering between 800 and 1100°F, as there is a drop in impact strength within this range and a drop in resistance to corrosion. This condition disappears when the tempering temperature is 1100°F or higher.
