5. PROCESSING:
Types 304 and 304L cannot be hardened by thermal treatment. Annealing: Heat to 1850o F to 2050 o F and cool at sufficiently high rates through 1500oF to 800oF to avoid precipitation of chromium carbides. Stress Relief Annealing: Cold worked parts should be stress relieved at 750oF for ½ to 2 hours.
