STAINLESS STEEL DEFINITION AND PRINCIPLE

Definition:

Steel containing more than 12% chromium, which can resist chemical attacks.

Principle:

Stainless steel does not mean it won't rust, but rather it is resistant to rusting. The principle involves the addition of chromium, forming a dense chromium oxide layer on the steel surface, effectively preventing further contact between the steel and air. This prevents oxygen in the air from entering the steel, thus preventing rusting.
