Oxygen Gas Cylinders by Material: Aluminium vs Stainless Steel
Oxygen gas cylinders are manufactured using different materials depending on the intended application, operating pressure, transport requirements, and regulatory standards.
The most common materials include aluminium alloy and stainless steel, each offering distinct mechanical and corrosion performance characteristics.
1. Based on Material of Construction
- Aluminium Alloy Seamless Cylinders (typically 6061-T6)
- Stainless Steel Cylinders (typically 304 / 316L grades)
| Aluminium Alloy Cylinder | Stainless Steel Cylinder |
| Excellent corrosion resistance in atmospheric and medical environments | Excellent corrosion resistance, especially 316L for aggressive or marine conditions |
| Lightweight (Density ≈ 2.7 g/cm³) | Heavy-duty construction (Density ≈ 7.9 g/cm³) |
| High strength-to-weight ratio | Higher absolute mechanical strength but lower weight efficiency |
| Commonly used for portable medical oxygen cylinders | Used for specialty gases, laboratory gases, and corrosive applications |
| Non-magnetic | May exhibit slight magnetism depending on grade and cold working |
| Typically manufactured under DOT-3AL and ISO 7866 standards | Typically manufactured under ISO 9809, EN 1964, or ASME pressure vessel standards |
