Abstract

A method of cladding a medium or high steel core rod with another metal includes a hot water quench at a temperature of about 160.degree. F. to boiling temperature and preferably about 195.degree. F. to 205.degree. F. with a subsequent quench in water at a temperature below a level of the first temperature and preferably at about ambient temperature. The clad material is found to be substantially devoid of objectionable oxide particles or surface sponge particles and the steel core substantially devoid of acicular transformation products permitting continued processing by deformation processes, such as wire drawing.
