1.4512 409 stainless steel is a Ferritic steel that offers good mechanical properties and high-temperature corrosion resistance. It contains 11 percent chromium which is the minimum amount for the formation of the passive surface film which gives stainless steels their corrosion resistance. It combines good elevated temperature corrosion resistance with medium strength, good formability, and overall cost.

Surface
Acid pickling – pre-passivation process of treating stainless steel parts with an acid solution, typically hydrochloric or sulfuric acid, which can remove oxide scale and heat tint while dissolving steel flecks embedded in the part.
Polishing – P grade sandpaper: P150, P200, P250, P300, P400, P500, P600, P700, P800
