发明名称 STAINLESS STEEL SHEET AND METHOD FOR MANUFACTURING SAME
摘要 Provided is a stainless steel plate having excellent washability and anti-glare property. The stainless steel plate is manufactured by performing temper rolling using a dull roller after the finish cold rolling and bright annealing. The stainless steel plate has an arithmetic mean roughness Ra of 0.2 to 1.2 µm in a direction perpendicular to the rolling direction of the steel plate surface. Furthermore, the stainless steel plate has a transfer ratio of 15 to 70% which is an area ratio of a portion onto which a dull pattern is transferred relative to the steel plate surface. In addition, the micro-pits being formed in the steel plate surface, having a depth of 0.5 µm or more, and having an opening area of 10 µm 2 or more, have an existing density in the steel plate surface of 10.0 or less per 0.01 mm 2 , and an opening area ratio in the steel plate surface of 1.0% or less.
