Does stainless steel require a surface finish?

Surface finish is an essential part of any stainless steel constitution and is therefore highly desirable and required for the application to work smoothly.

For those materials where appearances are important, the surface finish is designed in such a way to make the product look elegant.

What is Stainless Steel

  • I G or 2G:-It is also relatively coarse and unidirectional. The surface roughness in this type can be specified.
  • One p or 2 p:-This has the maximum specified coarse surface. It is the best surface for corrosion resistance.

If the application is non-decorative, a coarse surface with the correct specifications also leads to proper usage.

  1. Brewery items
  2. Scientific apparatus
  3. Kitchenware
  4. Food processing products

Today’s modern times, customers have become more inclined towards stainless steel products that speak of form, fit, and finish. Finishing has been evolved as an art where manufacturers constantly try to use cost-effective methods to give that service to the customers.
