| Synopsis: The demands for advanced properties of stainless steels in automotive exhaust systems are increasing to meet the requirements for lighter weight and stricter regulations for exhaust gas. However, the properties of steel materials used for automotive exhaust systems differ depending on parts, where the materials are to be used. Under the circumstance, advanced stainless steels suitable for each of the parts were developed by Kawasaki Steel by making full use of the latest production facilities in Chiba Works. That is, a stainless steel (R429EX: 15Cr-0.9Si-0.45Nb), having properties excellent in thermal fatigue resistance, resistance to high-temperature fatigue, oxidation resistance and formability, suitable for parts used in high temperature environment, like exhaust manifolds, for example, and stainless steels (R436LT: 18Cr-1.2Mo-Ti and R432LTM: 18Cr-0.5Mo-Ti), having condensate corrosion resistance, appropriate for use in humid environment, like parts, such as, mufflers, have been developed. |
