The treatment may be needed however on intricately shaped machine parts. WebMay 13, 2024 · The chromium in stainless steels is primarily responsible for the self-passivation mechanism. In contrast to carbon or low alloy steels, stainless steels must have a minimum chromium content of 10.5% (by weight) of chromium (and a maximum of 1.2% carbon). This is the definition of stainless steels given in EN 10088-1.
