The chemical composition of stainless steel boiler tubes ensures resistance to corrosion and scaling, especially under high-temperature conditions. Below is the typical chemical composition for SS 304 and SS 316 boiler tubes:
| Element | SS 304 (%) | SS 316 (%) | SS 316L (%) |
|---|---|---|---|
| Carbon (C) | ≤ 0.08 | ≤ 0.08 | ≤ 0.03 |
| Manganese (Mn) | ≤ 2.00 | ≤ 2.00 | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 | ≤ 0.045 | ≤ 0.045 |
| Sulfur (S) | ≤ 0.03 | ≤ 0.03 | ≤ 0.03 |
| Silicon (Si) | ≤ 1.00 | ≤ 1.00 | ≤ 1.00 |
| Chromium (Cr) | 18.0–20.0 | 16.0–18.0 | 16.0–18.0 |
| Nickel (Ni) | 8.0–10.5 | 10.0–14.0 | 10.0–14.0 |
| Molybdenum (Mo) | — | 2.0–3.0 | 2.0–3.0 |
Our Stainless Steel Instrumentation Tubing is tested for strength, ductility, and pressure-bearing capability.
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| SS 304 | ≥ 515 | ≥ 205 | ≥ 40 |
| SS 316 | ≥ 515 | ≥ 205 | ≥ 40 |
| SS 316L | ≥ 485 | ≥ 170 | ≥ 40 |
These mechanical features ensure advanced common performance under pressure and temperature variations.
These fittings are crucial in ensuring smooth, dependable, and ordinary fluid and gas waft at some stage in various high-stakes programs.

| 1/4″ | 6.35 | 0.035″ – 0.083″ | 0.9 – 2.1 |
| 3/8″ | 9.52 | 0.035″ – 0.083″ | 0.9 – 2.1 |
| 1/2″ | 12.7 | 0.035″ – 0.095″ | 0.9 – 2.41 |
| 3/4″ | 19.05 | 0.049″ – 0.120″ | 1.24 – 3.05 |
| 1″ | 25.4 | 0.065″ – 0.120″ | 1.65 – 3.05 |
Custom dimensions are available based on project requirements.
The following table gives an approximate weight per meter for common tube sizes (based on SS 304):
| OD (inch) | Wall Thickness (inch) | Weight (kg/m) |
|---|---|---|
| 1/4″ | 0.035″ | 0.19 |
| 3/8″ | 0.049″ | 0.35 |
| 1/2″ | 0.065″ | 0.52 |
| 3/4″ | 0.083″ | 0.88 |
| 1″ | 0.095″ | 1.32 |
