The invention relates to a method of making cladding tubes of zirconium alloys. According to the invention an improved resistance towards nodular corrosion under operating conditions in boiling water nuclear reactors can be achieved by carrying out a beta-quenching step, prior to the final cold rolling step, by heating 5-50% of the outer portion of the tube wall to a temperature in the beta-phase region and therafter rapidly cooling the tube. |
