ABSTRACT:
A process and apparatus for heat treatment of a steel article made of soft steel or the like comprising heating the steel article to a brazing temperature of 1100.degree.-1200.degree. C., then cooling the steel article in a furnace to a temperature of about 570.degree.-720.degree. C., and thereafter rapidly cooling the article. The article is heated to brazing temperature in an oxidation-free atmosphere and is also cooled in an oxidation-free atmosphere. The article can be rapidly cooled by contact with a surface pretreatment solution.
