All our products have comprehensive EN 10204 3.1/3.2 mill test certifications and evidence of conformity with PED 2014/68/EU. Our innovative cold drawing techniques reach dimensional tolerances of ±0.05 mm. Stringent eddy current and intergranular corrosion testing (EN ISO 3651-2) guarantee total matrix safety for chemical processing, pharmaceutical production and food-grade pipe systems.
What Makes EN 10216-5 1.4307 Tube the Preferred Choice for Pressure Applications
It is a particular European standard stainless-steel seamless product manufactured for high integrity pressure containment applications. This grade is concerned with crucial industrial difficulties, when welded joints are exposed to hostile chemical conditions.
The specification 1.4307 restricts the carbon content to below 0.030% unlike the normal austenitic grades. This very low carbon chemistry eliminates chromium carbide precipitation at grain boundaries during welding processes. You avoid expensive post-weld heat treatment and retain the entire corrosion resistance of the weld zones.
EN 10216-5 Technical delivery conditions for seamless tubes for pressure purposes. Dimensional tolerances are tight, and mechanical testing and intergranular corrosion testing are required. The tubes are solution annealed and quenched rapidly. This leads to a totally austenitic microstructure with improved passive layer stability.
Manufactured through precision multi-pass cold drawing, these tubes deliver exceptional concentricity and surface smoothness. You receive tubes with uniform wall thickness distribution, critical for stress calculation accuracy in pressure vessel design. Our manufacturing protocol includes 100% non-destructive testing through automated eddy current scanning and high-pressure hydrostatic leak verification.
