摘要： A stainless steel having excellent corrosion resistance to ozone added water, such as ozone added ultrapure water used in semiconductor manufacturing processes and the like, as well as a manufacturing method. The stainless steel comprises a base metal and an oxide film formed on the surface of the base metal, the base metal being a stainless steel which contains 12 to 30% of Cr, 0 to 35% of Ni, and 1 to 6% of Al and Si while the contents of the other alloying elements are limited to as low a level as possible, the oxide film mainly comprising Al oxide or a Si oxide or both. The oxide film may be formed on the base metal surface through the dry oxidation process or the wet oxidation process. In the stainless steel, metallic ions are rarely dissolved from the base metal into the ozone added water. Also, since the contents of alloying elements, other than Cr, Ni, Al, Si, and like necessary elements, are limited to a low level, the stainless steel exhibits excellent corrosion resistance and reduced particle emission.
摘要翻译： 具有优异的耐臭氧性的不锈钢，例如在半导体制造工艺中使用的加入臭氧的超纯水等，以及制造方法。 该不锈钢包括在母材表面形成的贱金属和氧化膜，贱金属为不锈钢，含有12〜30％的Cr，0〜35％的Ni和1〜6％的Al 和Si，而其它合金元素的含量被限制在尽可能低的水平，氧化物膜主要包含Al氧化物或Si氧化物或两者。 氧化膜可以通过干式氧化法或湿式氧化法在母材表面上形成。 在不锈钢中，金属离子很少从母体金属中溶解到加入臭氧的水中。 此外，由于除了Cr，Ni，Al，Si等必需元素以外的合金元素的含量被限制在低水平，所以不锈钢表现出优异的耐腐蚀性和减少的颗粒发射。
