S.s Tubes For Automotive Applications

AISI or SUS 409L 9 rade materialWe are a prime manufacturer of S.S. Tubes of Grade 409L which is titanium stabilized ferritic stainless steel. These stainless steel tubes are used in all automotives for following applications due to lightness and strength, improved mechanical properties, improved corrosion resistance at high temperature and appearance. All tubes are manufactured from fully annealed strips on modern continuous forming mills with TIG welding process under inert gas atmosphere. Tubes are cut and end finished.
