For estimation of the changes in the properties of metal the heat treatment which repeats the thermal heating during applying a lacquer-and-paint coating such as powder polymer paint + protective lacquer is modeled. Two basic mechanical characteristic such as yield strength and module of elasticity are analyzed. Such properties have positive results. The yield strength is increased, the module of elasticity is not changed. The first change may be used in the structural analyses of strength and also may be include in the process of heat treatment of metal construction.
