Key Mechanical Properties
Tensile Strength
- 304: 485–620 MPa | 316L: 485–620 MPa
The high tensile strength ensures resistance to deformation under load, making these pipes suitable for high-pressure systems like hydraulic lines and chemical reactors.
Bending Strength
- 304/316L: Excellent cold-forming capabilities. Compatible with stainless steel pipe bender tools for precise angles (up to 180°) without cracking. Ideal for complex installations in HVAC and shipbuilding.
Material Properties & Advantages
-
Corrosion Resistance
- 316L contains 2–3% molybdenum, enhancing resistance to chlorides, acids, and seawater.
- 304 offers general-purpose resistance to oxidation and organic chemicals.
-
High-Temperature Stability
- Retains structural integrity at temperatures up to 870°C (304) and 800°C (316L).
-
Hygienic & Easy to Clean
- Smooth surfaces prevent bacterial growth, compliant with FDA and EHEDG standards.
Weight Calculation Formula
Weight (kg/m) = (OD – WT) × WT × 0.02491
Example: For a schedule 10 stainless steel pipe (OD: 114.3 mm, WT: 6.0 mm):
(114.3 – 6.0) × 6.0 × 0.02491 = 16.1 kg/m
Why Stainless Steel Pipes Corrode?
Despite their name, stainless steel can rust under specific conditions:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts induces pitting.
- Low Oxygen Environments: Prevents chromium oxide layer formation, accelerating corrosion.
- Improper Welding: Unpassivated welds create vulnerable zones for rust.
Identification & Marking
- Laser Etching: ASTM-compliant labels include grade (304/316L), size, and heat number.
- Color Coding: Blue (316L) or yellow (304) bands for quick visual identification.
Applications
- Oil & Gas: Pipelines, valves, and stainless steel pipe flange connections.
- Medical: Implants, surgical tools, and sterile fluid transfer systems.
- Architecture: Handrails, facades, and structural supports.
