What grade of metal is 1.4408?
DIN EN 1.4408, also designated as GX5CrNiMo19-11-2, is a cast austenitic stainless steel grade under EN 10213 and EN 10283 standards. It is widely used for corrosion-resistant stainless steel castings, especially in valves, pumps, flanges, and marine components.
It is the cast equivalent of the wrought grade EN 1.4404 (AISI 316L), and includes molybdenum to improve pitting and crevice corrosion resistance.

What is 1.4408 material equivalent to?
| Standard | Equivalent Grade |
|---|---|
| EN / DIN | 1.4408 / GX5CrNiMo19-11-2 |
| AISI / ASTM | 316L (cast equivalent: ASTM A351 CF8M) |
| UNS | J92900 (CF8M), or S31603 (wrought equivalent) |
| JIS | SUS316LC (Cast) |
| ISO | G-X5CrNiMo19-11-2 (ISO 11971) |
Note: 1.4408 is a cast steel, so although chemically similar to 316L, its mechanical properties and microstructure may differ due to the casting process.
Chemical Composition of 1.4408
| Element | Typical Range (% by weight) |
|---|---|
| Carbon (C) | ≤ 0.07 |
| Silicon (Si) | 0.4 – 1.0 |
| Manganese (Mn) | ≤ 1.5 |
| Chromium (Cr) | 18.0 – 20.0 |
| Nickel (Ni) | 9.0 – 11.0 |
| Molybdenum (Mo) | 2.0 – 3.0 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.03 |
1.4408 stainless steel Mechanical Properties (As Cast, Heat Treated)
| Property | Value |
|---|---|

Is 1.4408 the same as 316L?
Not exactly. 1.4408 is the cast version of 316L with similar corrosion resistance but different mechanical behavior due to its microstructure and cooling rates.
What's the difference between 1.4408 and 1.4409?
is their carbon content, which affects welding and corrosion resistance. 1.4408 (GX5CrNiMo19-11-2) is a cast, corrosion-resistant steel with a higher carbon content (≤ 0.07%), while 1.4409 (GX2CrNiMo19-11-2) is its low-carbon counterpart (≤ 0.03%), offering better weldability and higher resistance to intergranular corrosion.
