Abstract
A hot rolled steel sheet having a specific composition and having a specific small grain size of ferrite constituting the steel sheet has high resistances against secondary-work embrittlement and brazing embrittlement and is adapted for ultra-deep drawing. The specific small grain size of the ferrite can be obtained by limiting the hot rolling condition of a slab having the specific composition.
