Pure fluorine gas may be stored in steel cylinders where the inside surface is passivated, as long as the temperature is kept below 200 °C. Above that temperature, nickel is required.

(Note: Passivation, in physical chemistry, refers to a material becoming "passive," that is, being less affected by environmental factors such as air and water.)
