Like low alloy or carbon steels, martensitic stainless steels are similar in structure to ferritic, but can be hardened or strengthened by heat treatment—which can also make them more brittle. This is due to the addition of carbon. The main alloying element of this family is chromium. The oil industry is a h…Consider the corrosion resistance of this family of stainless steels to be ‘moderate-to-good’ with those levels increasing with chromium content. Ferritic stainless steel contains iron-chromium alloys with body-centered cubic crystal structures—they are plain chromium stainless steels with varying chromium content between 12 and 18%. But that means they are a bit more difficult to produce than standard austenitic stainless steel.
