Importance of Surface Finishing Stainless Steel

The use of stainless steel is increasing across several industries due to its strength, formability, durability, and corrosion resistance properties. It is the widely chosen raw material in the manufacturing of appliances, food processing equipment, material handling machinery, aerospace, military devices, and defense systems, just to name a few. However, finding reliable stainless steel distributors can sometime be a challenge.

At Alliant Metals, we have the in-house stock, expertise, and years of experience to meet all of your industries needs. Here’s a more in-depth look at the world of stainless steel finishing that some of the novice may not fully understand.

How Can the Performance and Shelf Life of Stainless Steel be improved?

Before using in applications, stainless steel is coated with suitable surface finishes. This is done to achieve the following:

  • To withstand the hostile environmental conditions, including dust, hydrocarbon solutions, harsh chemicals, and solvents.
  • To enhance corrosion, impact, abrasion, and scratch resistance.
  • To attain a smooth polished appearance. This is imperative when using stainless steel as the raw material for manufacturing, medical, and lab apparatuses.
  • To enhance the cleanliness of the metal surface. This is essential when using the metal in the assembly of equipment/systems in food processing organizations. Stainless steel that is polished with suitable finishes is easier to clean than unpolished surfaces
  • To improve the cosmetic and aesthetic appeal of metal. Stainless steel with an excellent aesthetic look is essential in the manufacturing of beer kegs, furniture, and stairways.
  • To improve mechanical properties, making them perfect for applications in aggressive environments.
