Abstract
This slab is a slab of high-Al steel containing C: 0.02 mass % to 0.50 mass % and Al: 0.20 mass % to 2.00 mass %, in which, in a case where [Zr], [Ti], [Al], and [N] each represent a content (mass %) in the slab, a Zr content and a Ti content satisfy a relationship of [Zr]+0.2×[Ti]≥4/3×[Al]×[N], and the Zr content satisfies a relationship of 0.0010 mass %≤[Zr].
