  • Method of quenching
    Patent number: 4404044
    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.

  • Metal quenching process
    Patent number: 4381205
    Abstract: A process of quenching metal using as the quenching medium an aqueous solution containing from about 0.5% to 50% by weight of a liquid, water-soluble, capped polyether polyol obtained by reacting ethylene oxide and at least one lower alkylene oxide having 3 to 4 carbon atoms, e.g. propylene oxide, with an active hydrogen compound, such as a lower glycol, to prepare a heteric or block copolymer, and further reacting the copolymer with an alpha olefin oxide, the polyol having a molecular weight of from about 7000 to 15,000.
