SUS310S SS316L 304L Stainless Steel Pipe And Tubes 0.25mm To 6mm
Product Overview
SUS310S 304L SS316L Stainless Steel Pipes and Tubes ranging from 0.25mm to 6mm, manufactured with precision cold rolling processes for superior dimensional accuracy and surface quality.
Material Grades
Austenitic Steel (Mainstream):
- 304 (0Cr18Ni9): General purpose stainless steel for general corrosive environments and food contact applications
- 304L (00Cr19Ni10): Ultra-low carbon version with excellent resistance to intergranular corrosion, ideal for heavily corrosive environments where post-weld annealing is not possible
- 316 (0Cr17Ni12Mo2): Molybdenum-added grade with improved resistance to pitting corrosion and seawater
- 316L (00Cr17Ni14Mo2): Ultra-low carbon version of 316 with the best overall corrosion resistance
- 321 (1Cr18Ni9Ti): Titanium-added grade with improved resistance to intergranular corrosion and high temperature resistance
Duplex Steel:
- 2205 (S32205): Combines advantages of austenitic and ferritic steels, offering high strength and excellent resistance to chloride stress corrosion, suitable for harsh environments (seawater, chemical industries)
Special High-Performance Steels:
- 904L, 254SMO: High molybdenum content grades used in highly corrosive media (sulfuric acid, phosphoric acid)
Dimensions and Specifications
Cold rolling processes enable production of tubes with precise control over outer diameter and wall thickness:
- Outer Diameter Range: Typically Φ6mm ~ Φ273mm (small and medium diameters are strengths)
- Wall Thickness Range: 0.5mm ~ 20mm and above
Typical Specifications Examples:
| Application |
Specification |
| Precision Instrument Tubes |
Φ10mm x 1.0mm |
| Heat Exchanger Tubes |
Φ19mm x 2.0mm |
| Hydraulic Cylinder Barrels |
Φ50mm x 5.0mm |
| Food Industry Tubes |
Φ33.7mm x 1.5mm |
Key Precision Indicators
Core value of cold-rolled tubes with stringent dimensional tolerances:
| Parameter |
Tolerance Range |
| Outer Diameter Tolerance |
±0.10mm to ±0.30mm (depending on specifications) |
| Wall Thickness Tolerance |
±10% of wall thickness (higher-level requirements reaching ±5%) |
| Ovality |
Excellent control ensuring near-perfect circular cross-section |
Surface Treatment and Condition
Industrial Pipe Surfaces:
- Acid-washed (AP): Silvery-white or light gray matte surface with uniform passivation film - common delivery condition with good corrosion resistance
- Bright (BA): Mirror-like surface after heat treatment under protective atmosphere with high internal cleanliness - suitable for demanding applications (food, electronics)
- Cold-rolled (cold-drawn): Surface with cold-worked metallic luster and high hardness - requires further processing or can be used directly
Decorative Pipe Surfaces: Additional processing including polishing (mirror finish), wire drawing, sandblasting, and electroplating (titanium plating)
