Automotive Exhaust Systems
S.S. Tubes for Automotive Exhaust Systems
Introduction and Scope - Bhandari stainless steel tubes are used in all automotive exhaust systems for lightness and strength, improved mechanical properties, improved corrosion resistance at high temperature and appearance, ASTM A - 268 generally covers Seamless or Welded, Ferritic or Martensitic SS tubing for general services.
Materials - Majority of the users are specifying AISI or SUS 409L/436LT grade material, which is Titanium, stabilized ferritic grade. These tubes are also supplied in AISI 304 grade for better service life and appearance.
Size Range
- OD: 12.70 mm to 76.20 mm
- Thickness: 1.0 mm to 2.0 mm
- Length: As per customer specifications
Process Of Manufacture - All tubes are manufactured from fully annealed strips on modern continuous forming mills with TIG welding process under inert gas atmosphere. Tubes are cut , end finished.
Test
