X2CrNi19-11 (EN 1.4306) and X2CrNi18-9 (EN 1.4307) are both low-carbon austenitic stainless steels commonly known as 304L variants. While 1.4307 is the standard low-carbon 304L grade, 1.4306 contains higher nickel content (10–13%) for improved corrosion resistance, especially in welded or aggressive environments. Both offer excellent weldability, but 1.4306 is preferred in pharmaceutical, food, and chemical industries where enhanced corrosion performance is critical.
X2CrNi19-11 (1.4306) vs. X2CrNi18-9 (1.4307)
| Property | X2CrNi19-11 (1.4306) | X2CrNi18-9 (1.4307) |
|---|---|---|
| Common Name | High-nickel 304L | Standard 304L |
| Carbon Content (C) | ≤ 0.030% | ≤ 0.030% |
| Nickel Content (Ni) | 10.0–13.0% | 8.0–10.5% |
| Chromium Content (Cr) | 17.5–19.5% | 17.5–19.5% |
| Weldability | Excellent | Excellent |
| Corrosion Resistance | Slightly better | Good |
| Magnetism | Non-magnetic (annealed) | Non-magnetic (annealed) |
| Typical Standard | EN 10088-1, ISO, AISI 304L | EN 10088-1, AISI 304L |
1.4307 vs. 1.4306 : Which One Should You Choose?
Choose 1.4306 if your application involves welding, chemical exposure, or demanding hygienic conditions.
Choose 1.4307 for general stainless steel applications where budget and standard corrosion resistance are sufficient.
