What are ISO 15730 - Metallic and other inorganic coatings about?
ISO 15730 specifies the information to be supplied by the purchaser to the finisher.
ISO 15730 specifies requirements and test methods for electropolishing as a means of smoothing and passivating stainless steel alloys in the S2XXXX, S3XXXX, and S4XXXX series, and the precipitation-hardened alloys.
Who is ISO 15730 - Metallic and other inorganic coatings for?
ISO 15730 on Metallic and other inorganic coatingsis useful for:
- Stainless steel manufacturing plant
- D polishing industries
- Inorganic coating companies
Why should you use ISO 15730 - Metallic and other inorganic coatings?
According to ISO 15730, the electropolishing removes a small but finite amount of metal from the surface that, in addition to smoothing and brightening, produces a hygienically clean surface desirable for use by manufacturers of food processing and medical equipment.
ISO 15730 provides improved passivation, electropolishing provides many other benefits. Some examples are surface stress relief, removal of surface carbon and oxides and reduction of friction.
The quality of passivation depends on the type of stainless steel, the formulation of the electropolishing solution and the conditions of operation. Free iron on the surface of the stainless steel is removed resulting in improved corrosion resistance. No further chemical treatment is necessary in order to passivate the stainless steel surface. Surface smoothing obtained by electropolishing also improves passivation.
