CPM M4 Steel Review - Knife User

The answer is No, its not stainless steel, to be considered stainless steel the CPM M4 must have a minimum of 12% of chromium in it. Therefore its a tool steel . It can be considered carbon steel since it has high carbon (more than 1% of carbon in the chemical composition).

Cpm m4 vs bohler s690 BladeForums

Aug 27, 2011 · Apr 18, 2010. Under the "standards" section, Bohler's data sheet lists S690 as being approximately equivalent to AISI (American Iron and Steel Institute) M4, although like knarfeng said the composition isn't a perfect match either to that or to CPM-M4. But given that the compositions are very similar and that both CPM-M4 and S690 are powder steels (albeit produced using different
