Due to the presence of chromium in their composition, stainless steel bars are able to resist nitric acid. This is because chromium forms a protective oxide layer, known as the passive layer, on the surface of the stainless steel. Acting as a barrier, this passive layer prevents direct contact between the nitric acid and the underlying metal.
The chromium oxide layer is highly stable and has the ability to self-heal. This means that even if it sustains damage, it quickly reforms, ensuring continuous protection against corrosion caused by nitric acid. In addition to chromium, stainless steel bars often contain other alloying elements like molybdenum, which further enhance their resistance to nitric acid.
Overall, the combination of chromium and other alloying elements creates a material that is both strong and resistant to corrosion, making it capable of withstanding the damaging effects of nitric acid.
