All values/properties mentioned in the brochure/website are dependent on the type of stainless steel and its condition.
Besides the chemical composition of the material, the results also depend on pre- heat treatment and/or machining.
The passive layer has the best properties if the microstructure of the base material is uniform. Non-uniformities such as sulfides, deformation martensite and delta ferrite also contribute to reduced corrosion resistance.
The look of a product after treatment depends on the delivery conditions of the part.
The treatment and specification of end products must be determined in advance in agreement with Aalberts Surface Technologies Eindhoven B.V.
