스테인리스 강 스트립의 어닐링 동안 형성된 산화물이, 산 또는 용융된 염 기반 산 세척 대신에 연마성 브러시로 제거된다. 일부 양태들에서, 본 발명의 스테인리스 강 스트립은, 어닐링 전에 희토류 원소 또는 관련 전이 금속으로 처리된 다음, 어닐링 후에 브러싱되어 모든 산화물들이 제거된다. 브러시의 선택은 통상적으로 폴리싱된 스테인리스 강에 대해 피니싱된 외관을 부여할 수 있다. Oxides formed during annealing of stainless steel strip are removed with abrasive brushes, in lieu of acid or molten salt based pickling. In some embodiments, the stainless steel strip is treated with a rare earth element or a related transition metal before annealing, and then brushed after annealing to remove any oxides. The selection of brushes can impart a finished appearance to conventionally polished stainless steel.
