Cherry Red Surface Hardening Compound is an easy way to harden soft, low carbon metals. Cherry Red in combination with high heat creates a tough, durable, hardened finish on the surface of metals. Produces a wear surface (surface hardening) on low carbon steel, low alloy steel, iron.
- Thoroughly heat the part to cherry red in color. Be sure part 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 part air cool, then brush off excess compound. Cherry Red is water soluble and excess can be removed with water and a little brushing.
