What is BA Stainless Steel Strip?
BA (Bright Annealed) stainless steel strip is produced by annealing in a controlled oxygen-free atmosphere, resulting in a smooth, bright, and highly reflective surface.
Compared with 2B finish, BA has:
Higher surface brightness
Better aesthetic appearance
Lower surface roughness
Improved cleanliness for precision applications
301 vs 304 vs 316 BA Stainless Steel Strip
| Grade | Strength | Corrosion Resistance | Formability | Cost | Main Application |
|---|---|---|---|---|---|
| 301 | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | Medium | Low | Springs, elastic parts |
| 304 | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ | High | Medium | General industrial use |
| 316 | ⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ | High | High | Marine, chemical industry |
👉 301 = high elasticity
👉 304 = universal industrial grade
👉 316 = highest corrosion resistance
