Determine the role of chromium in stainless steel

 Stainless steel elements of the decision is only one genus, which is chrome, stainless steel each contain a certain amount of chromium. To date, no chromium-free stainless steel. Chromium stainless steel performance have become key elements determine the fundamental reason is that after adding chrome Stainless Steel Cold Heading Wire as an alloying element, prompting its internal contradictions in favor of the motion to resist corrosion damage aspects of development. This change can be explained in the following areas:

     ① chromium electrode potential iron-based solid solution to improve Binding Binding Wire .

     ② electronic chromium iron absorption iron passivation
     Passivation is blocked due to the anode reaction caused by the corrosion resistance of metals and alloys can be improved on. Theory of metals and alloys constitute passive lot, mainly film theory, adsorption deals on electronic arrangement.
