CHERRY RED HARDENING COMPOUND
AREA OF APPLICATION
Cherry Red is a fast-acting hardening powder, which when applied to steels will develop a case hardening surface. Cherry Red is used on parts such as knives, punches, drills, chisels, cutting edges, and small tools.
HOW TO USE CHERRY RED:
• Thoroughly heat part until its cherry red in color. Be sure the part (or section of the part to be hardened) is completely heated for best results.
• Coat part in Cherry Red compound. Cover all surfaces to be hardened. Compound will blister and harden. Reheat part to cherry red color.
• Quench in water, oil, or let cool and brush off excess compound. Cherry Red is water soluble, and excess can be removed with water and a little brushing.
• Repeat steps one through three as needed to raise the Rockwell value.
TEST RESULTS USING CHERRY RED ON MILD STEEL:
