ABSTRACT Aqueous quenching baths containing as an essential constituent a water-soluble salt of a copolymer of maleic, citraconic, or itaconic anhydride and a long chain alpha olefin are useful in quenching metal at cooling rates which are slower than that of water, and may be as slow as or slower than those obtained using a hydrocarbon oil as the quenching medium.
