PROPRIETARY CarTech 20Cb-3 Stainless Heat Treatments

Annealing: Heat to 941-1010°C (1725-1850°F) for thirty minutes per 25.4 mm of thickness and water quench. Do not overheat.

In this condition is stabilized against possible intergranular corrosion.

At a sacrifice of stabilization, lower hardness for improved formability may be obtained by annealing up to 1149°C (2100°F). The higher temperatures are permissible if steel will not be subject to welding or heating over 538°C (1000°F).

Cannot be hardened by heat treatment - it can be hardened only through cold working.

Stress relieving is safe at 538°C (1000°F).
