Compliance: EN 10217-7 Technical Condition 2 (TC2) for 1.4401 Pipes
The European standard EN 10217-7 specifies the technical delivery conditions for welded tubes made of stainless steel for pressure purposes. Given the critical applications of 316, the **1.4401 pipes Manufacturer** production is typically finalized with the highest level of testing and certification.
Technical Condition 2 (TC2) - High Integrity
This is the most common and stringent requirement for critical pressure applications. All weld seams must undergo Non-Destructive Testing (NDT).
- Non-Destructive Testing (NDT): Mandatory weld seam testing (e.g., Eddy Current, Ultrasonic, or Radiographic) is required along the entire length of the weld.
- Testing: Requires Hydrostatic or Eddy Current testing.
- Documentation: Full 3.1 or 3.2 Inspection Certificate is required (TÜV, Lloyd's, DNV, etc.).
- Applications: Offshore, Petrochemical, and highly corrosive fluid handling systems.
Technical Condition 1 (TC1) - General Use
Suitable for less critical applications where the full cost and time of NDT are not justified.
- Non-Destructive Testing (NDT): Not mandatory unless specified by the purchaser.
- Testing: Requires flattening or flanging test and a leak tightness test.
- Documentation: 2.2 or 3.1 Inspection Certificate.
- Applications: Structural tubing, low-pressure conveyance, and non-critical components.
Grade 1.4401 (X5CrNiMo17-12-2 / TP316) Chemical Composition & Key Properties
The EN 1.4401 grade contains Molybdenum, giving it enhanced corrosion resistance over 304. This composition is key for its use in severe environments. We are a reliable 1.4401 pipes Supplier and X5CrNiMo17-12-2 pipes Supplier globally.
| Chemical Composition of EN 1.4401 (X5CrNiMo17-12-2) - % by mass | ||||||||
|---|---|---|---|---|---|---|---|---|
| Grade | C (Max) | Si (Max) | Mn (Max) | P (Max) | S (Max) | Ni | Cr | Mo |
| 1.4401 (X5CrNiMo17-12-2) | 0.07 | 1.00 | 2.00 | 0.045 | 0.015 | 10.0 - 13.0 | 16.5 - 18.5 | 2.0 - 2.5 |
| *Related Grade* 1.4404 (316L) | 0.03 | 1.00 | 2.00 | 0.045 | 0.015 | 10.0 - 14.0 | 16.5 - 18.5 | 2.0 - 3.0 |
Key Properties of 1.4401 (316) Pipes
- Pitting Resistance: The 2.0-2.5% Molybdenum dramatically increases resistance to localized corrosion (pitting and crevice) in chloride environments.
- Creep Resistance: Has superior creep and stress-rupture properties, especially at higher temperatures compared to 304.
- Welding: Good weldability. For heavy sections or highly corrosive service after welding, the low-carbon version **1.4404 (316L)** is recommended.
- Alternative Grades: The low-carbon 1.4404 is generally stocked and supplied as it satisfies the requirements of both 1.4401 and 1.4404.

EN 10217-7 Grade 1.4401 Pipes — Frequently Asked Questions
Find answers to common questions about the EN 10217-7 standard, the TP316 pipe price, and Molybdenum-enhanced stainless steel.
Molybdenum (Mo), added to 1.4401, significantly improves the material's resistance to pitting and crevice corrosion, particularly in chloride-containing environments like seawater or certain chemical solutions, a vulnerability of standard 1.4301 (304).
The low-carbon equivalent of 1.4401 (316) is 1.4404 (316L) or X2CrNiMo17-12-2. We typically supply 1.4404 as it is highly weldable and resistant to weld decay without loss of the critical Molybdenum content.
1.4401 (316) is often used in less severe stages of desalination. For full seawater resistance or highly concentrated brine, a higher alloy is typically specified, such as a Super Austenitic (e.g., 6Mo) or Duplex/Super Duplex steel, which we also supply.
Due to its Mo content, 1.4401 exhibits better creep strength and resistance to sensitization (when compared to 304) at temperatures up to 870°C, making it a reliable choice for elevated temperature pressure systems.
