Polishing Performance of 304 Series Stainless Steel

Introduction to the Polishing Performance of 304 Series Stainless Steel

The 304 series stainless steel is known for its excellent surface processing performance. It is compatible with various surface processing techniques commonly used in the market.

1. Dry Grinding and Brushing

Dry grinding and brushing, producing long and short filament patterns, are the most common techniques. After processing, 304 series stainless steel displays good decorative effects, suitable for general decorative materials. Typically, one frosting pass is sufficient.

This method is cost-effective, easy to operate, and widely used, making it essential for processing centers. As a result, most centers offer frosted plates with long and short filaments, with 304 steel comprising over 80% of their output.

2. Oil Grinding and Brushing

Oil grinding enhances the decorative appeal of 304 series stainless steel, making it popular for panels in elevators and home appliances. Cold-rolled 304 stainless steel usually achieves excellent results with one grinding pass. Some centers also offer oily grinding for hot-rolled stainless steel, which yields results comparable to cold-rolled oil grinding.

Oil grinding can create long or short filament patterns. Elevators typically use long filaments, while small appliances and kitchen utensils feature both types.

3. 8K Processing

In 8K processing, 304 stainless steel outperforms the 200 series. After grinding the 2B cold-rolled surface, a mirror effect is usually achieved with one pass. The 8K grinding process, using nitric acid and red iron oxide, is inexpensive due to the low cost of equipment, making it widely adopted.

4. Titanium Coating

Titanium coating provides a luxurious finish, making it a popular choice for high-end decorative materials. The 304 series stainless steel has been extensively used in titanium decoration for elevators and building materials.

Conclusion

The 304 series stainless steel is widely used in various decorative applications due to its excellent surface processing properties and strong corrosion resistance. Despite the growth of the 200 and 400 series, the 304 series remains a preferred choice for surface decoration materials, maintaining a significant market share.
