A LOW COST FERRITIC STAINLESS STEEL MICROALLOYED BY HIGHER Nb FOR AUTOMOTIVE EXHAUST SYSTEM
Automotive engine exhaust gas after combustion of fuel,and the gas will be liquefied in the rear of automotive exhaust system.A lot of corrosive anions existing in the condensate make corrosion of the exhaust system materials.Therefore,once pitting perforation,automotive exhaust system will fail directly.In 1980s,automotive exhaust manifold was made of Si-Mo ductile iron,mufflers and the tail pipe were made of carbon steel or aluminized steel.But with higher emission standards carried out,the improvement of engine performance and the higher exhaust temperature as well as the needs of the automotive light-weighting,we need the higher corrosion resistance of the material for automotive exhaust systems to meet the requirements.
