Abstract
A heat-shrink band for a cathode ray tube (CRT) has a light weight, corrects the deformation of an object, such as a panel of a CRT due to the air pressure, effectively prevents implosion of the CRT, can suppress the color deviation, and in addition is excellent in formability. The method of fabricating the heat-shrink band includes a composition of cold rolled steel sheet such that the heat-shrink band offers both a high elongation characteristic at an ambient temperature and a high stress of yielding point characteristic after the heat-shrink process. The reduction of the weight of the heat-shrink band contributes to an overall reduction of the weight of the CRT.
