LOW-Cr FERRITIC STAINLESS STEEL EXCELLENT IN FORMABILITY AND HIGH-TEMPERATURE PROPERTIES AND METHOD FOR MANUFACTURING SAME

摘要

Disclosed are low-Cr ferritic stainless steel excellent in formability and high-temperature properties and a method for manufacturing the same. According to embodiments of the present invention, there can be provided low-Cr ferritic stainless steel and a method for manufacturing the same to have excellent high-temperature strength and high-temperature oxidation resistance corresponding to high-Cr ferritic stainless steel while securing formability without increasing the Cr content or adding Nb by optimizing the contents of Ci, Si, and Sn and utilizing solid solution strengthening and precipitation strengthening.;COPYRIGHT KIPO 2020
