Jun 04, 2025
Leave a message
X2CrNi19-11, commonly identified as EN 1.4306, is a low-carbon austenitic stainless steel with enhanced corrosion resistance. It is often compared to similar grades such as X5CrNi18-10 (1.4301), X2CrNi18-9 (1.4307), and AISI 304L, but subtle differences in chemical composition and usage make it unique.

1.4306 stainless steel chemical composition
1.4306 has a lower carbon content and higher nickel content than standard 304 or 304L grades, which improves corrosion resistance and reduces the risk of intergranular corrosion, especially in welded structures.
| Element | Content (%) |
|---|---|
| C (Carbon) | ≤ 0.030 |
| Si (Silicon) | ≤ 1.00 |
| Mn (Manganese) | ≤ 2.00 |
| P (Phosphorus) | ≤ 0.045 |
| S (Sulfur) | ≤ 0.015 |
| Cr (Chromium) | 17.5 – 19.5 |
| Ni (Nickel) | 10.0 – 13.0 |
| N (Nitrogen) | ≤ 0.10 |
1.4306 stainless steel mechanical properties
1.4306 stainless steel has excellent weldability and does not require post-weld heat treatment. It is commonly used in food processing equipment, pharmaceutical containers, chemical storage tanks and pressure vessels.
| Property | Typical Value |
|---|---|
| Density | 7.9 g/cm³ |
| Tensile Strength (Rm) | 500 – 700 MPa |
| Yield Strength (Rp0.2) | ≥ 190 MPa |
