Strengthening Manual for Screws (Vol. 22) What is a passive state?
Introducing the reasons why stainless steel is resistant to rust in a blog format!
The reason stainless steel is resistant to rust is that "its surface is passivated." Now, what does this passivation mean? When chromium is added to iron, it combines with oxygen, meaning it oxidizes, and a thin protective film is formed on the surface of the steel. This phenomenon is called "passivation," and adding chromium in amounts of 10.5% or more is the condition for passivation to occur. The oxidized film that results from passivation is called the "passivation film," and this film prevents the progression of rust. *For more detailed information, please refer to the related links.
