Ferritic stainless steel

Chromium is the main alloy element in this group. It may reach amounts higher than 25%, in combination withcarbon content lower than 0.2%. They cannot be hardened through quenching( martensitic transformations). 

Theyare more stainless than martensitic steels under oxidizing conditions or in an atmosphenic milieu. Since the grains are not refined through heat treatment, additional care must be taken when reheating them at high temperatures Due to their high content of chromium, these steels tend to weaken when exposed to 500C for a long time, what

requires attention when selecting the pieces to be applied. 

They have good cold conforming under any conditions because of their ferritic structure(soft They have magnetic sensitivity (ferromagnetism).
