What is 304 mirror stainless steel plate?
304 mirror stainless steel plate (national standard 06Cr19Ni10, American standard ASTM A240 304) is based on 304 austenitic stainless steel, and is a mirror-grade high-precision plate made by mechanical polishing or electrolytic polishing. The surface glossiness is ≥85GU, and the roughness is Ra≤0.2μm. It is widely used in high-end architectural decoration, kitchen and bathroom equipment, medical equipment, etc.

What are the core advantages of 304 mirror stainless steel plate?
The reflectivity of 304 mirror stainless steel plate is over 90%, supporting No.8 mechanical mirror (preferred for decoration) and EP electrolytic mirror (high cleanliness requirement), and the cost is only 60%-70% of 316L mirror plate, which is the first choice for non-strong corrosion scenarios.
304 stainless steel corrosion resistance: resistant to atmospheric, fresh water, and salt spray corrosion, 24-hour salt spray test without rust spots, corrosion resistance is 3 times that of 430 stainless steel.
Compared with ordinary 304 stainless steel plate, what is the difference between the mirror plate?
The 304 stainless steel mirror plate has a lower surface roughness and higher gloss after polishing (ordinary plate is 2B surface, Ra≤0.8μm). After polishing and passivation treatment, the surface oxide film is more uniform, and the anti-fouling and anti-rust ability is improved by 20%-30%.
