What Are Stainless Steel 304 Micro Tubes?

Stainless Steel 304 micro tubes are small stainless steel tubes that are fabricated with extremely small diameter and thin wall thickness, having tight tolerance dimensions. The stainless steel 304 micro tube is developed with the aim that the performance of the tubes used under pressure would be adequate whereas standard tubes have failed to give required results.

Chromium and nickel treatments in SS 304 grade result in the formation of a stable oxide layer which aids the micro tube against contamination caused due to corrosion from moisture, oxidation, chemical reactions, etc. They can be employed for several industrial applications that require maximum endurance without contamination with minimum maintenance.
