The suitability of flame-straightening methods now used on conventional ship steels for the higher strength ship steels is questionable. The report discusses some of the potential problem areas that need evaluation to examine this subject. Based on a survey of pertinent literature it is shown that only limited data applicable to this subject are available. The data analysis covered the nature of distortion, flame-straightening techniques, and the effects of both single and combined thermal cycles and plastic strain cycles on material properties. An experimental program is presented that is designed to generate background data on conventional steels and several higher strength steels directly pertinent to flame straightening. These data will subsequently be evaluated to ascertain suitability of the flame-straightening procedure for various ship steels.
