304 Ultra-clean precision steel pipe Performance
304 stainless steel sanitary pipe is a high-quality stainless steel pipe material widely used in food, medical and other fields with extremely high hygiene requirements. Its national standard is 0Cr18Ni9, the American standard is TP304, and the Japanese standard is SUS304.
What is the role of surface treatment of 304 stainless steel sanitary pipes?
Polishing: Ra≤0.4μm (mechanical polishing + electrolytic polishing) reduces medium retention and inhibits bacterial growth.
Passivation: Enhances Cr₂O₃ oxide film, salt spray test exceeds 1000 hours, and corrosion resistance is increased by 30%.
What is the difference between 304 sanitary pipe and 316L sanitary pipe?
Applicable scenarios: 316L is suitable for high-salt or acidic environments (such as seawater desalination, strong acid media in medicine).
Cost: 316L is 20-30% more expensive than 304.
