铁素体系不锈钢板、盖部件以及铁素体系不锈钢板的制造方法
摘要：
本发明提供清洗性、防眩性和亲水性优异的铁素体系不锈钢板。在冷精轧和光亮退火后使用毛面辊进行平整轧制而成的铁素体系不锈钢板中，钢板表面上的与轧制方向垂直的方向上的算术平均粗糙度Ra为0.2μm以上且1.2μm以下。并且，钢板表面上的毛面图案的转印率为15％以上且70％以下。此外，在钢板表面上形成的深度为0.5μm以上、开口面积为10μm2以上的微坑的存在密度为每0.01mm2存在10.0个以下，且该微坑的开口部面积率为1.0％以下。并且，在钢板表面上形成的覆膜由以SiO2为主体的氧化物构成，该以SiO2为主体的氧化物至少含有Si、N、Al、Mn、Cr、Fe、Nb、Ti以及O作为C以外的覆膜形成元素，并且Si含量为10原子％以上，N含量为10原子％以下。
摘要（英）：

Provided is a ferritic stainless steel sheet which exhibits excellent cleanability, anti-glare properties, and hydrophilicity. In this ferritic stainless steel sheet, which is temper rolled using a dull roll after being subjected to finishing cold rolling and bright annealing, the steel sheet surface has an arithmetic average roughness Ra in a direction orthogonal to the rolling direction of at least 0.2 [mu]m, but not more than 1.2 [mu]m. Furthermore, the dull-pattern transfer rate to the steel sheet surface is at least 15%, but not more than 70%. Moreover, micropits which are formed in the steel sheet surface, have a depth of at least 0.5 [mu]m, and have an opening area of at least 10 [mu]m2, have a presence density of not more than 10.0 per 0.01 mm2, and an opening area ratio of not more than 1.0%. Furthermore, a film formed on the steel sheet surface is formed from an oxide which mainly consists of SiO2, includes, as film-forming elements other than C, at least Si, N, Al, Mn, Cr, Fe, Nb, Ti, and O, has a Si content of at least 10 atomic%, and has a N content of not more than 10 atomic%.
