Finish types of stainless steel coil 304

2B Finish

The 2B finish is a widely used standard finish for stainless steel coils, including 304. It is characterized by a smooth, reflective surface with a slight cold-rolled dullness.
This finish is suitable for a variety of applications, including kitchen appliances, architectural elements, and industrial equipment.

No. 1 Finish

The No. 1 finish is a hot-rolled, annealed, and descaled finish. It results in a non-uniform, rough surface with scale remnants from the hot rolling process.
While not as smooth as 2B, the No. 1 finish is often used for applications where appearance is less critical, and the emphasis is on the mechanical properties of the material.

BA (Bright Annealed) Finish

The BA finish involves annealing the stainless steel in a controlled atmosphere to produce a bright, reflective surface. It is characterized by a mirror-like appearance.
This finish is popular in applications requiring a high level of reflectivity, such as decorative and architectural elements.

No. 4 Finish

The No. 4 finish is achieved by polishing the stainless steel with abrasive belts or brushes. It results in a moderately reflective surface with a uniform linear grain pattern.
This finish is commonly used for architectural trims, kitchen equipment, and other applications where a polished appearance is desired.

8K/Mirror Finish

The 8K or mirror finish is a highly reflective finish achieved through additional polishing steps beyond the BA finish. It provides a mirror-like, distortion-free surface.
This finish is utilized in high-end applications, such as decorative and ornamental pieces, where a flawless appearance is essential.

Brushed Finish

The brushed finish involves creating a consistent, textured pattern on the surface through brushing or abrasive processes. It results in a matte appearance with visible parallel lines.
This finish is often chosen for architectural and design applications, offering a unique and aesthetic surface texture.

Hot Rolled Stainless Steel Coil

  • Hot rolling involves heating the steel above its recrystallization temperature, resulting in a scaled surface.
  • The 304 hot rolled stainless steel coil exhibits improved mechanical properties, making it suitable for heavy-duty applications in construction and manufacturing.

Cold Rolled Stainless Steel Coil

  • Cold rolling involves reducing the thickness of the steel through compression at room temperature.
  • The 304 cold rolled stainless steel coil offers precise dimensions and a smooth surface, making it suitable for applications requiring tight tolerances, such as automotive components.
