Can stainless steel tubing burn in pure oxygen or fluorine?

Stainless steel tubing can indeed burn in pure oxygen or fluorine, especially at high temperatures. When exposed to pure oxygen or fluorine, materials such as stainless steel can undergo combustion or oxidation reactions that are significantly more vigorous than in the presence of air.

This is primarily due to the increased availability of oxygen in these environments, which facilitates the burning process. While stainless steel is known for its corrosion resistance and strength, it is not immune to combustion under the right conditions. High temperatures can provide the energy necessary to initiate and sustain these reactions.

In contrast to the other possible answers, which suggest varying degrees of fire resistance or conditional combustion, the reality is that stainless steel can ignite when the right factors—such as sufficient heat and reactive environments—are present.
