Martensites and ferrites



As a company specialized in pickling and passivation of stainless steel, we pickle steel with an austenitic structure, as well as pickling and passivation of martensitic and ferritic types of stainless steel.
These types of corrosion-resistant steel require specific procedures to maintain optimal properties. Thanks to our expertise and experience, we ensure that your stainless steel materials are not only perfectly treated, but also protected for long-term use.

Martensitic stainless steel

Martensitic steel is known for its high strength and hardness, but requires specific handling during surface treatment. Our pickling and passivation processes are designed to preserve the mechanical properties of martensitic steel while ensuring its corrosion resistance.

Ferritic stainless steel

Ferritic steel is characterized by high corrosion resistance in chloride environments. It is suitable for high temperature applications. Our specialist pickling and passivation procedures ensure that this type of steel retains its unique properties and is also better protected against external influences.



What are the advantages of pickling and passivation of special stainless steel materials?
  • Optimum corrosion protection: With the right chemical treatment, we restore the protective layers on the surface of the processed parts, thereby both extending the service life and increasing their durability.
  • Maintenance of mechanical properties: Despite the chemical treatment, the materials remain mechanically intact and are ready for further use.
How do we pickle special materials?

We approach each material knowing that it has its own specific needs. For martensitic and ferritic stainless steel, we perform a material condition analysis. We then select the appropriate chemical solutions and procedures. If the customer requires its own processing procedure be used, the material is processed according to the procedure delivered. Our many years of experience ensure that every step, from pickling to passivation, is carried out with the utmost precision and expertise.
