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.
