Stainless 304 vs 316
Chemistry per ASTM A240. The L grades (304L and 316L) have the same chemistry with carbon at 0.03% max for welding heavy sections.
| Property | 304 | 316 |
|---|---|---|
| Chromium | 17.5–19.5% | 16.0–18.0% |
| Nickel | 8.0–10.5% | 10.0–14.0% |
| Molybdenum | — | 2.0–3.0% |
| Pitting resistance (PREN) | ~19 | ~25 |
| Chlorides and salt | Moderate | High |
| Best for | Food, kitchens, equipment, architecture | Marine, chemicals, pharma, desalination |
| Price | Base | Higher, with nickel and molybdenum |

Frequently asked questions
What are stainless 304 pipe prices today?+
Stainless is priced per kilo: weight × the price per kg for the grade and finish. The price moves with nickel and the exchange rate, so we send today's price in writing on request instead of a fixed number that may be out of date.
What is the difference between schedule pipe and sanitary tube?+
Schedule pipe (ASTM A312) is sized by NPS and schedule 10/40/80 for pressure, steam and structures. Sanitary tube (ASTM A270) is thin-walled with a polished bore for dairy, juice and pharma lines.
Should I choose seamless or welded pipe?+
Seamless for high pressure and temperature. Welded is cheaper, more precise and enough for most water, food and structural lines.
Do the pipes come with a mill certificate?+
Yes. Every lot ships with a mill test certificate showing chemistry, mechanical properties and heat number.
How do I work out the weight of a stainless pipe?+
Weight in kg/m = (OD − wall) × wall × 0.0251 (in mm), at a density of 8.0 g/cm³. A 2 inch schedule 40 pipe (60.3 × 3.91 mm) weighs about 5.54 kg/m, about 33 kg per 6 m length.
304 or 316 pipe for water and food lines?+
304 or 304L is enough for most water, dairy and juice lines. Choose 316L for high-chloride water, aggressive cleaning chemicals or sites near the sea.
