    When heat treating steel to harden it, use these compounds to protect the surfaces you don’t want to harden. Also known as stop-off paint, all are compatible with gas mixtures that are used in gas carburizing and carbonitriding processes. Brush or dip the compounds on your surfaces and then air dry before heat treating. After heating, any residue that’s left behind can be easily washed away with hot water.
    Solvent Based—Solvent-based compounds stand up to temperature and humidity better than water-based compounds, so they dry quicker. To maintain their original consistency, use the optional xylene to thin these compounds.
    Water Based—Water-based compounds emit less VOCs (volatile organic compounds) than solvent-based compounds for less impact on the environment. To maintain their original consistency, simply use water to thin these compounds.
    Cannot Be Sold To—Compounds cannot be sold to the listed areas due to VOC regulations.

    Harden steel parts without cracks or distortion. This oil cools slower and more evenly than water for consistent hardening and less scrap.
    Match the oil’s cooling rate to your steel’s alloy. Carbon steel and low-alloy steel (less than 5% alloy content) typically require faster cooling. High-alloy steel (more than 5% alloy content) benefits from slower cooling. You'll also need to account for the shape of your part. The more intricate the part, the slower the quench time you should choose.
    Slow Quench—Also known as marquenching oil, use this oil in high-temperature quenching baths. It may not fully harden low-alloy steels.
