FERRITIC STAINLESS STEEL WITH EXCELLENT HIGH-TEMPERATURE SALT INJURY RESISTANCE AND HIGH-TEMPERATURE STRENGTH |
摘要 |
A heat-resistant ferritic stainless steel for use as a high-temperature member such as the material of an automotive exhaust system, which is reduced in the total content of C and N and contains Ti or Zr added to thereby reduce the total content of free C and free N and which secures the amount of solid solution of W, Nb and Mo to thereby secure solid solution hardening and high-temperature salt injury resistance effectively for long, whereby the high-temperature strength can be held both at the initial stage and in mid-course of its use and the high-temperature salt injury resistance and the oxidation resistance can be achieved at the same time. |
