Abstract
This invention provides a relatively thick roll-bonded laminate that exhibits a high Erichsen value and excellent molding workability. Such roll-bonded laminate is composed of a stainless steel layer and a non-stainless steel metal layer, and it is characterized in that thickness T is 0.2 mm to 3 mm and a correlation between a proportion PSUS of thickness TSUS of the stainless steel layer relative to thickness T and a half width FWHM200 of a peak exhibiting a crystal plane orientation (200) determined by X-ray diffraction analysis of the stainless steel layer side satisfies the correlation represented by the formula: FWHM200≤0.0057PSUS+0.4.
