A gas generating composition for use in a pretensioner, which generates less CO gases and chlorine-containing gases after combustion and is superior in thermal stability and in producing and processing, is obtained. The gas generating composition for use in a pretensioner comprises a highly thermal
A gas generating composition for use in a pretensioner, which generates less CO gases and chlorine-containing gases after combustion and is superior in thermal stability and in producing and processing, is obtained. The gas generating composition for use in a pretensioner comprises a highly thermal stabilized binder, an oxidizing agent, and, if required, a chlorine-neutralizing agent as major ingredients. The gas generating composition can improve thermal stability of a gas generating agent, can reduce the amount of CO gases, is excellent in producing and processing, and can reduce chlorine-containing gases if required.

The process of claim 8, wherein introducing bending strains into the steel comprises introducing bending strains of at least about 1 yield strain and no more than about 7 yield strains. 10. The process of claim 8, wherein introducing bending strains into the steel comprises introducing bending strains of at least about 4 yield strains and no more than about 5 yield strains. 11. The process of claim 8, wherein the precipitation strengthening substance is selected from the group consisting of niobium, vanadium, titanium, niobium plus titanium, and niobium plus vanadium. 12. The process of claim 11, wherein the target temperature is at least about 350 C. and no more than about 450 C. 13. The process of claim 8, wherein the precipitation strengthening substance has an equilibrium solution temperature in the steel and the selected dissolving temperature is at least about 50 C. greater than the equilibrium solution temperature of the precipitation strengthening substance. 14. The process of claim 8, wherein the selected dissolving temperature is at least about 1050 C. and no more than about 1350 C. 15. A process for producing steel plate having a desired microstructure, and precipitation strengthening particles of a desired particle size and volume fraction for enhanced precipitation strengthening, comprising: a) heating steel containing a precipitation strengthening substance to a selected dissolving temperature selected to dissolve substantially all of the precipitation strengthening substance in the steel; b) processing the steel to produce a steel plate having the desired microstructure; c) cooling the steel plate to a selected target temperature at which the desired microstructure is essentially stable and at which those precipitation strengthening particles that form tend to be of the desired particle size; and d) with the steel plate at the selected target temperature, introducing bending strains into the steel by levelling the steel plate so as to introduce dislocations in the crystal structure of the steel to increase the kinetics of precipitation, and thus the volume fraction, of precipitation strengthening particles of the desired particle size. 16. The process of claim 15, wherein levelling the plate comprises passing the plate through a hot leveller comprising upper rollers and lower rollers offset from the upper rollers, such that passing the steel through the hot leveller straightens the plate without unduly detrimentally reducing the thickness of the plate. 17. The process of claim 15, wherein introducing bending strains into the steel comprises introducing bending strains of at least about 1 yield strain and no more than about 7 yield strains. 18. The process of claim 15, wherein introducing bending strains into the steel comprises introducing bending strains of at least about 4 yield strains and no more than about 5 yield strains. 19. The process of claim 15, wherein the precipitation strengthening substance is selected from the group consisting of niobium, vanadium, titanium, niobium plus titanium, and niobium plus vanadium. 20. The process of claim 19, wherein the target temperature is at least about 350 C. and no more than about 450 C. 21. The process of claim 15, wherein the precipitation strengthening substance has an equilibrium solution temperature in the steel and the selected dissolving temperature is at least about 50 C. greater than the equilibrium solution temper
