Compliance: EN 10217-7 Technical Condition 2 (TC2) for 1.4306 Pipes
The European standard EN 10217-7 specifies the technical delivery conditions for welded tubes made of stainless steel for pressure purposes. For critical systems, the low-carbon 1.4306 pipes Manufacturer and X2CrNi18-9 Pipes Manufacturer production ensures materials are tested to the most stringent level.
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, and Industrial systems requiring high reliability.
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 1.4306 (X2CrNi18-9 / TP304L) Chemical Composition & Key Properties
The EN 1.4306 grade is the European low-carbon austenitic stainless steel, engineered for superior post-welding corrosion resistance. Its chemical composition ensures the material's fitness for aggressive, welded environments. We are a reliable 1.4306 pipes Supplier and TP304L pipes Supplier globally.
| Chemical Composition of EN 1.4306 (X2CrNi18-9) - % by mass | |||||||
|---|---|---|---|---|---|---|---|
| Grade | C (Max) | Si (Max) | Mn (Max) | P (Max) | S (Max) | Ni | Cr |
| 1.4306 (X2CrNi18-9) | 0.03 | 1.00 | 2.00 | 0.045 | 0.015 | 9.0 - 11.0 | 17.0 - 19.0 |
| *Related Grade* 1.4301 (304) | 0.07 | 1.00 | 2.00 | 0.045 | 0.015 | 8.0 - 10.5 | 17.5 - 19.5 |
Key Properties of 1.4306 (304L) Pipes
- Low-Carbon Benefit: Maximum 0.03% Carbon prevents the formation of Chromium Carbides in the heat-affected zone during welding, thereby eliminating "weld decay."
- Welding: Excellent fusion welding characteristics; generally does not require post-weld solution annealing.
- Corrosion: Very good resistance in atmospheric, freshwater, and many aggressive chemical environments.
- Alternative Grades: This is an excellent alternative to 1.4301 when high weld integrity in corrosive service is required.

EN 10217-7 Grade 1.4306 Pipes — Frequently Asked Questions
Find answers to common questions about the EN 10217-7 standard, the 304L pipe price, and welding with 1.4306.
The 1.4306 (304L) grade has a lower carbon content (max 0.03%) than 1.4301 (max 0.07%). This makes 304L highly resistant to intergranular corrosion (weld decay) after welding, allowing it to be used in corrosive environments without a costly post-weld solution annealing heat treatment.
While 1.4306 (304L) has better post-weld corrosion resistance, the slightly higher strength 1.4301 (304) is generally preferred for very high-temperature applications where creep resistance is the main concern. However, 1.4306 is suitable for most general-to-moderate high-temperature service where it is frequently welded.
To maintain the low-carbon benefits of 1.4306 (304L) and prevent weld decay, the recommended filler metal is the corresponding low-carbon grade, typically ER308L (or 1.4316) for TIG/MIG welding.
Due to its lower carbon content, 1.4306 (304L) typically has slightly lower mechanical properties (yield and tensile strength) compared to 1.4301 (304). Both grades, however, easily meet the minimum pressure ratings specified in the EN 10217-7 standard.
