Compliance: EN 10217-7 Technical Condition 2 (TC2) for 1.4541 Pipes
The European standard EN 10217-7 specifies the technical delivery conditions for welded tubes made of stainless steel for pressure purposes. For high-temperature, critical systems, the 1.4541 pipes Manufacturer and X6CrNiTi18-10 pipes Manufacturer production strictly adheres to the stringent TC2 requirements.
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: High-temperature process lines, power generation, and chemical applications.
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 1.4541 (X6CrNiTi18-10 / TP321) Chemical Composition & Key Properties
The EN 1.4541 grade is a Titanium-stabilized austenitic stainless steel, making it ideal for service at high temperatures. Its composition, particularly the required Titanium content, ensures it resists intergranular corrosion after welding. We are a reliable 1.4541 pipes Supplier and TP321 pipes Supplier globally.

Key Properties of 1.4541 (321) Pipes
- Stabilization: Titanium (Ti) binds with carbon, preventing chromium depletion and ensuring corrosion resistance at high temperatures.
- High-Temp Service: Excellent performance in continuous service up to 900°C (1650°F) where thermal stress and creep resistance are critical.
- Welding: Superior weldability. Typically welded with matching grade ER321 filler metal (or ER347). No post-weld annealing required.
- Alternative Grades: Often used interchangeably with 1.4550 (347), which uses Niobium for stabilization.

EN 10217-7 Grade 1.4541 Pipes — Frequently Asked Questions
Find answers to common questions about the EN 10217-7 standard, the TP321 pipe price, and high-temperature service with 1.4541.
The addition of Titanium (Ti) to 1.4541 stabilizes the carbon content. This prevents Chromium Carbides from precipitating at grain boundaries during exposure to high temperatures (425°C to 815°C / 800°F to 1500°F), thereby maintaining the material's full corrosion resistance after welding and in service.
TP321 is specifically chosen for applications involving sustained exposure to high heat and corrosive conditions, such as aircraft exhaust manifolds, high-temperature chemical process lines, boiler superheaters, and heat exchanger tubes where operating temperatures exceed 550°C.
Both grades resist weld decay. 1.4306 (304L) does it via low carbon content, which is effective for most applications. 1.4541 (321) uses Titanium stabilization, making it the preferred and more reliable choice for highly corrosive, sustained high-temperature service where 304L's creep strength might be inadequate.
Yes, we also supply the Niobium (Niobium and Tantalum) stabilized equivalent, **1.4550 (X6CrNiNb18-10)**, which corresponds to AISI/ASTM TP347. Both 1.4541 and 1.4550 are used for similar high-temperature, stabilized applications.
