Abstract

Novel metal quenchants, which are particularly suitable for quenching steels, are provided. The quenchants comprises an aqueous solution to a polyoxyalkylene glycol and an oxazoline polymer. Such quenchants are more oil-like in their behaviour than the aqueous polyoxyalkylene glycol quenchants of the prior art and hence are less likely to introduce stresses into metals such as steel when they are quenched.
