Surface Finish Types of Stainless Steel Coil 302

a. 2B Finish:

  • A standard finish providing a smooth, reflective surface suitable for diverse applications.
  • The 2B finish balances functionality with an aesthetic appeal, making it versatile across industries.

b. No. 1 Finish:

  • Achieved through hot rolling, this finish results in a rough surface, prioritizing mechanical properties over appearance.
  • Often chosen for applications where strength is a critical requirement.

c. BA (Bright Annealed) Finish:

  • Controlled annealing produces a bright, reflective surface, ideal for decorative purposes.
  • The BA finish enhances the visual appeal of 302 stainless steel, making it suitable for architectural and design applications.

d. No. 4 Finish:

  • Created through polishing, it yields a uniform matte appearance with a linear grain pattern.
  • The No. 4 finish is ideal for applications requiring a visually pleasing yet non-reflective surface.

e. 8K/Mirror Finish:

  • An advanced polishing process results in a highly reflective, mirror-like surface.
  • This finish is often chosen for high-end applications where a flawless appearance is paramount.

302 Hot Rolled Stainless Steel Coil

  • Involves heating the steel above its recrystallization temperature, resulting in a scaled surface.
  • The hot-rolled 302 stainless steel coil exhibits enhanced strength, making it suitable for structural and heavy-duty applications.

302 Cold Rolled Stainless Steel Coil

  • Achieved through compression at room temperature, this process produces a smooth surface with improved dimensional accuracy.
  • Ideal for applications requiring tight tolerances and a polished appearance.
