FE-CR ALLOY WITHOUT RIDGING

摘要

PURPOSE: A Fe-Cr alloy is provided which exhibits a good ridging resistance and has an excellent formability and a percentage of elongation without annealing the high-temperature processed sheet before being cold reduced. CONSTITUTION: The Fe-Cr alloy comprises of 0.08 wt.% or less of C; about 8 wt% or more of Cr; 1.5 wt.% or less of Mn; less than 0.020 wt.% of Al; 0.05 wt.% or less of N; 1.5 wt.% or less of Si; less than 2.0 wt.% of Ni, 0.1 wt.% or more of Ti; and the balance being Fe and remaining elements; wherein the {multiply Ti(wt.%) by N(wt.%)}/Al(wt.%) is at least 0.14 and the Ti content satisfies the following equation: (Ti/48)/{(C/12)+(N/14)}>1.5.
