Claims
- 1. A process for preparing a brazed steel article from steel parts to be joined by solder which consists essentially of the steps of heating said parts with said solder to a brazing temperature of 1100.degree.-1200.degree. C., to effect joining thereof, followed by cooling the brazed steel article in a furnace to a temperature of about 570.degree.-720.degree. C. in 5-10 minutes and then rapidly cooling the brazed steel article, wherein said steel contains from 0.02 to 0.25% carbon.
- 2. A process as claimed in claim 1 wherein the heating to the brazing temperature is effected in an oxidation-free atmosphere.
- 3. A process as claimed in claim 1 wherein the rapid cooling is effected by contacting the steel with a liquid.
- 4. A process as claimed in claim 3 wherein the liquid has a temperature of 5.degree.-45.degree. C.
