Development of Automotive Fuel System Parts made of Ferritic Stainless Steel

摘要

We developed an automotive fuel inlet pipe to meet these regulations for vehicle emission: Low Emission Vehicle n (LEV- n ) and Partial-Credit Zero Emission Vehicle (P-ZEV), by using ferritic stainless steel SUS436L with cationic electrodeposition coaling. It has high corrosion resistance, no stress corrosion cracking susceptibility and high durability, which correspond to 15 years and 150,000 miles guaranteed in a fuel system environment. This fuel inlet pipe made of ferritic stainless steel has been applied to mass production cars.
