PROPRIETARY CRUCIBLE 20Cb PLUS Heat Treatments

Forged: The recommended forged range is 2100-2250°F (1149-1233°C). Annealed: For optimum resistance to sensitization should be annealed 1700-1750°F (929-955°C) for 1/2 hour per inch of thickness and water quench. For maximum cold formability and at some sacrifice of corrosion resistance after sensitization. May be annealed at 2000-2100°F (1094-1149°C) followed by a water quench.
