Stainless Steel Metal Material Surface Treatments For Food And Beverage

Stainless steel surface treatments enhance its properties, improve aesthetics, and increase resistance to corrosion and wear.

1. Passivation
Description: A chemical process that removes free iron and enhances the chromium oxide layer.
Benefits: Increases corrosion resistance and protects against rust.
2. Polishing
Description: Mechanical process that smooths the surface using abrasives.
Benefits: Achieves a shiny, reflective finish; improves appearance and corrosion resistance.
3. Electroplating
Description: Involves depositing a layer of metal (like nickel or chrome) onto the stainless steel.
Benefits: Enhances aesthetics and provides additional corrosion resistance.
4. Anodizing
Description: An electrochemical process that increases the thickness of the oxide layer on the metal surface (more common with aluminum but can be applied to stainless steel).
Benefits: Improves corrosion resistance and allows for color finishes.
5. Shot Peening
Description: A mechanical process that bombards the surface with small balls (shot) to induce compressive stresses.
Benefits: Increases fatigue strength and resistance to cracking.

About us:

Wuxi Xinfengcheng Metal Products Co., Ltd. was established in 2003 and is headquartered in Wuxi City, Jiangsu Province, an important gathering place for China's stainless steel industry. The company focuses on the research and development, production and sales of stainless steel materials. With "seamless steel pipes" as its core products, it is committed to providing high-performance and high-standard metal material solutions for the global industrial field.

R&D and Innovation
- Jointly build a "Stainless Steel Pipe Joint Laboratory" with the School of Materials Science and Engineering of Shanghai Jiaotong University to overcome the problem of material stability under high temperature and high pressure environment;
- Independently develop "multi-roll cold rolling forming technology" to reduce the surface roughness (Ra) of the pipe to below 0.8μm, reaching the mirror-grade standard.
