How to Increase the Service Life of Stainless Steel Tubes?

Stainless steel is typically classified according to its matrix structure into:

Ferritic Stainless Steel Tube. Contains 12% to 30% chromium. Its corrosion resistance, toughness, and weldability improve with increasing chromium content, and it exhibits good resistance to chloride stress corrosion.

Austenitic Stainless Steel Tube. Contains more than 18% chromium, along with about 8% nickel and small amounts of molybdenum, titanium, nitrogen, and other elements. It offers comprehensive performance and can resist corrosion from various media.

Austenitic-Ferritic Duplex Stainless Steel Tube. Combines the advantages of austenitic and ferritic stainless steels and exhibits superplasticity.

Martensitic Stainless Steel Tube. Has high strength but relatively poor plasticity and weldability.

Precipitation-Hardening Stainless Steel Tube. Offers excellent formability and good weldability.

Based on composition, it can be classified into Cr series (SUS400), Cr-Ni series (SUS300), Cr-Mn-Ni series (SUS200), and precipitation hardening series (SUS600).

Methods to increase the service life of 316L Stainless Steel Tube:

Cleaning Method

When cleaning the surface of the Stainless Steel Tube, care must be taken to avoid scratching the surface. Do not use cleaning agents containing bleach or abrasive components, steel balls, or grinding tools. To remove the cleaning agent, rinse the surface with clean water at the end of the cleaning process.

How to Deal with Dust

For dust and easily removable dirt on the surface of the Stainless Steel Tube, clean with water or a mild soap solution. For adhesive residues, wipe with alcohol or organic solvents (such as ether, benzene).

Grease

For oil or lubricant stains on the surface of the Stainless Steel Tube, wipe with a soft cloth first, then clean with a neutral detergent, ammonia solution, or specialized cleaning agent.

Adherent Rust

For rust stains on the surface of the Stainless Steel Tube caused by contaminants, use commercially available rust prevention paste to remove the surface contaminants or rust, then clean thoroughly with water or a mild alkaline soap solution.
