What Is SS 304 Square Pipe?
304 stainless steel square tubing is a hollow structural profile made of AISI 304 austenitic stainless steel, with a chromium content of approximately 18% and a nickel content of approximately 8%. It combines excellent corrosion resistance, durability, and aesthetics. It is non-magnetic in the annealed state, durable, and easy to weld, making it widely applicable in various structural, industrial, and construction applications, such as railings, food processing equipment, and marine components.
SS 304 Square Pipe Weight per Meter (Reference Chart)
Below is a standard weight chart per meter for SS 304 square pipes (based on density 7.93 g/cm³).
Actual weight may vary slightly depending on manufacturing tolerance.
| Size (mm) | Wall Thickness (mm) | Weight per Meter (kg/m) |
|---|---|---|
| 20 × 20 | 1.5 | 0.89 |
| 25 × 25 | 1.5 | 1.15 |
| 30 × 30 | 1.5 | 1.40 |
| 40 × 40 | 2.0 | 2.38 |
| 50 × 50 | 2.0 | 3.02 |
| 60 × 60 | 2.5 | 4.45 |
| 75 × 75 | 3.0 | 6.96 |
| 100 × 100 | 3.0 | 9.45 |
| 100 × 100 | 4.0 | 12.4 |
What is the density of SS 304 stainless steel?
The density of SS 304 is 7.93 g/cm³, which is used to calculate weight per meter.
Formula for weight per meter:
Where:
A = outer width (mm)
T = wall thickness (mm)
ρ = material density (7.93 for SS304)

What is the difference between SS 304 and 316 square pipes?
The main difference is that SS 316 has superior corrosion resistance due to the addition of molybdenum (approximately 2%), while SS 304 is less expensive and suitable for general use where extreme corrosion isn't a factor. This makes SS 316 better for marine environments, chemicals, and high temperatures, while SS 304 is common for food and beverage, general indoor and outdoor use, and is often the more affordable option.
