Choosing the Right Finishing Technique
Stainless steel finishing can be a complex to solve. There are many different types of surface finishes and profiles that may be required. If you’re feeling stuck and unsure where to turn, the experts at Kramer Industries have broken down the basics of the most popular stainless steel finishes.
Matte Finish
One of the three most common stainless steel finishes is matte. A matte or mill finish, as it is known, means that the metal is left with a dull appearance. This is typically used for non-aesthetic results, or when the parts are not immediately visible. For non-machined metals, this finish is produced by “cold rolling” stainless steel. This method provides a smoother and less pitted surface. It is then softened and de-scaled in acid solution. Finally, the steel is polished on rolls to enhance its smoothness. Typical uses for matte finish include chemical plant equipment, pharmaceutical equipment, paper mill equipment, and sewage equipment.
Brushed Finish
Brushed finishes can vary from supplier to supplier, even batch to batch, and in different manufacturing conditions. Brushed finishes produce a distinctive muted look with a pattern of parallel, directional lines. While offering an aesthetic appeal, it isn’t too reflective but usually has some brightness. Some drawbacks of brushed stainless steel finishes are that corrosion resistance is reduced and the grooves are susceptible to rust. Created by sanding the steel in one direction, this process is used for jewelry, home appliances, architecture, and automotive design.
Mirror Finish
Highly reflective mirror finishes are created by polishing stainless steel. This process enhances both the appearance and the consistency of the finish, making cleaning the surface easier, while masking the after-effects of welding.
Stainless steel mirror finishes are created by treating the surface with a series of progressively finer and finer abrasives. A rolling procedure is used to simulate the appearance of mechanical abrasion. During this stage, it is crucial to remove deep scratches. Any defects will be noticeable. The final task involves buffing the surface to create a reflective finish. Mirror finishes are popular because they improve corrosion resistance of wall panels, clean rooms, and reflectors of all kinds.

Frequently Asked Questions (FAQs)
1. What is the most common stainless steel finish?
Matte, brushed, and mirror finishes are the three most common stainless steel finishes, each offering different levels of appearance, reflectivity, and functionality.
2. What is the difference between brushed and mirror stainless steel finishes?
Brushed finishes have directional lines and a muted appearance, while mirror finishes are highly reflective and created through multiple polishing and buffing stages.
3. Which stainless steel finish is best for corrosion resistance?
Mirror finishes generally offer better corrosion resistance because the smooth surface reduces areas where moisture and contaminants can collect.
4. Where are matte stainless steel finishes typically used?
Matte finishes are commonly used in industrial environments such as chemical plants, pharmaceutical equipment, paper mills, and sewage systems where appearance is not critical.
5. How can Kramer Industries help with stainless steel finishing?
Kramer Industries provides expert guidance, finishing equipment, abrasive media, and outsourced finishing services to help achieve the ideal stainless steel surface finish for any application.
