Understanding EN 10217-7: TC1 vs. TC2 Certification
The European standard EN 10217-7 specifies the technical delivery conditions for welded tubes made of stainless steel for pressure purposes. As a professional EN 10217-7 Welded Pipe Exporter, we ensure full compliance with the two primary technical conditions (TC) required by our global clients.
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: Chemical, Petrochemical, Power Generation, and other high-pressure 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: General fluid lines, exhaust systems, and structural applications not under high internal pressure.
Grade 1.4301 (X5CrNi18-10 / AISI 304) Chemical Composition & Key Properties
The EN 1.4301 grade is a standard austenitic chromium-nickel stainless steel, globally recognized for its excellent weldability, fabrication properties, and resistance to a wide range of corrosive media. This grade's composition is strictly controlled to meet the requirements of EN 10217-7.

|---|---|---|---|---|---|---|---|
| Grade | C (Max) | Si (Max) | Mn (Max) | P (Max) | S (Max) | Ni | Cr |
| 1.4301 (X5CrNi18-10) | 0.07 | 1.00 | 2.00 | 0.045 | 0.015 | 8.0 - 10.5 | 17.5 - 19.5 |
| *Related Grade* 1.4307 (304L) | 0.03 | 1.00 | 2.00 | 0.045 | 0.015 | 8.0 - 10.5 | 17.5 - 19.5 |
Key Properties of 1.4301 Pipes
- Corrosion: Excellent resistance to atmospheric corrosion and many inorganic/organic chemicals.
- Welding: Excellent weldability via all standard fusion methods; typically welded with 1.4316 / ER308L filler metal.
- Working Temperature: Suitable for use up to 870°C in intermittent service and 925°C in continuous service.
- Alternative Grades: We also supply the low-carbon version, 1.4307 (304L), for applications requiring post-weld annealing freedom.

EN 10217-7 Grade 1.4301 Pipes — Frequently Asked Questions
Find answers to common questions about the EN 10217-7 standard, the 1.4301 pipe price, and the difference between 304 and 304L in European standards.
TC2 (Technical Condition 2) is the more stringent condition, requiring mandatory non-destructive testing (NDT) of the weld seam, either radiographically or ultrasonically, along with other full material testing. TC1 (Technical Condition 1) has less stringent testing requirements, often used for less critical pressure applications.
The European grade EN 1.4301 (or X5CrNi18-10) is the direct equivalent of the American grade AISI/ASTM TP304 stainless steel. It is an austenitic alloy used for general corrosion resistance.
Yes. EN 1.4307 is the European equivalent of AISI 304L (low carbon). This grade is preferred when pipes will be welded and the application is sensitive to intergranular corrosion, as the lower carbon content prevents carbide precipitation during welding.
EN 10217-7 pipes are typically supplied with plain ends, suitable for butt-welding into a piping system. We can also supply pipes with bevelled ends (BW) upon request for direct welding, ensuring precise fit-up to EN 10253 standards.
