<p>Metal, such as steel, is quenched in a quenching bath comprising an aqueous solution of a substituted oxazoline polymer, one example of which is polyethyloxazoline having a molecular weight of 5000 to 500,000. The bath is capable of providing quenching effects similar to those produced by oil quenchants, as well as quenching times between those provided by oil and water. </p> |
