Stainless steel tubes according to EN 10216-5 “Seamless steel tubes for pressure purposes. Technical delivery conditions. Part 5: Stainless steel tubes”. Carbon steel welded tubes according to EN 10305-2 and EN 10305-3 and stainless steel welded tubes according to EN 10217-7 and EN 10296-2 available on request.
Carbon Steel: E235, E355. Other non-alloy quality steels (E255, 410) and alloy special steels (25CrMo4, 24CrMo4) available on request.
Stainless Steel:  AISI 304/L, AISI 316/L. Other grades (300 and 400 series) available on request.
Tolerances: according to EN 10305 and EN ISO 1127. Precision tubes with reduced tolerances or special dimensional accuracy available on request.
Delivery condition: +N / +C / +A / +LC. Pickled and annealed or BA (bright annealed).
Surface: these tubes are characterized by a smooth, bright, reflective finish produced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling during annealing.

Range of applications: the applications for precision steel tubes for automotive industry are determined by special technical features such as:

  • High dimensional accuracy for inside and outside diameters;
  • Smooth surfaces achieved by drawing;
  • Improved strength characteristics due to cold forming.

Typical applications include:

  • Fuel Injectors;
  • Fuel-rail systems (distribution pipe);
  • Tubular parts for seats;
  • Transmission parts;
  • Cable protectors;
  • Components and vehicle parts.
