What is No.4 Finish in Sheets?

No.4 Finish is a highly sought-after surface finish for stainless steel sheets, renowned for its exceptional properties that render it suitable for a diverse array of applications. This finish is characterized by a semi-reflective, finely brushed, and uniformly textured surface, which enhances both its aesthetic appeal and functional qualities. 

To achieve the No.4 Finish, stainless steel sheets undergo a meticulous mechanical polishing process involving the use of abrasives. This technique not only imparts a consistent and visually pleasing appearance but also grants the sheets enhanced durability and corrosion resistance. 

The semi-reflective nature of the No.4 Finish lends a touch of elegance to stainless steel sheets, making them an ideal choice for architectural and interior design applications. Whether it’s for cladding, wall panels, elevator interiors, or decorative trim, this finish adds a touch of sophistication to any space. 

Moreover, the finely brushed texture of the No.4 Finish provides an excellent balance between aesthetics and functionality. The uniform surface texture not only masks fingerprints and scratches but also facilitates easy cleaning and maintenance. This makes No.4 Finish stainless steel sheets a popular choice for high-traffic areas such as restaurants, hospitals, and public spaces where cleanliness and hygiene are of utmost importance. 

In addition to its visual appeal and easy maintenance, the No.4 Finish also boasts excellent resistance to corrosion and staining. The mechanical polishing process not only smooths out any surface imperfections but also creates a protective layer on the stainless steel, making it highly resistant to environmental factors such as moisture, chemicals, and oxidation. This makes No.4 Finish stainless steel sheets suitable for outdoor applications, as they can withstand harsh weather conditions and maintain their pristine appearance over time. 

Furthermore, the versatility of the No.4 Finish extends beyond its visual and functional attributes. It serves as an excellent base for further surface treatments such as electroplating, powder coating, or screen printing, allowing for endless customization possibilities. This makes No.4 Finish stainless steel sheets a preferred choice for industries ranging from automotive to electronics, where unique finishes and branding are crucial.

Stainless Steel Used in No.4 Finish Sheets: 

No.4 finish is a popular surface finish for stainless steel sheets. It is characterized by a brushed or satin-like appearance, with a dull, non-reflective finish. This finish is achieved by mechanically polishing the surface with abrasive materials.

Several stainless steel grades can be used to produce No.4 finish sheets. The choice of grade depends on various factors such as the intended application, desired properties, and budget. Here are some commonly used stainless steel grades for No.4 finish sheets:

  1. AISI 304: This is the most widely used stainless steel grade and is suitable for a wide range of applications. It offers good corrosion resistance, excellent formability, and high strength. AISI 304 is often used in kitchen appliances, food processing equipment, and architectural applications.
  2. AISI 316: This grade is known for its superior corrosion resistance, especially in environments with chlorides or acids. It contains molybdenum, which enhances its resistance to pitting and crevice corrosion. AISI 316 is commonly used in marine applications, chemical processing equipment, and pharmaceutical industries.
  3. AISI 430: This ferritic stainless steel grade offers good corrosion resistance and high-temperature oxidation resistance. It is less expensive than austenitic grades like 304 and 316, making it suitable for cost-sensitive applications such as automotive trim, kitchen utensils, and decorative purposes.
  4. AISI 441: This grade is a dual-stabilized ferritic stainless steel, containing both titanium and niobium. It offers good corrosion resistance, high-temperature strength, and excellent formability. AISI 441 is commonly used in exhaust systems, heat exchangers, and other high-temperature applications.
  5. AISI 201: This grade is a low-cost alternative to AISI 304, offering similar mechanical properties and corrosion resistance. It is often used in decorative applications, such as furniture, handrails, and architectural trim.
