904L rustfrit stål_Tianjin Fang stål Co., Ltd.

904L Stængen af rustfrit stål

904LGrade er et ustabilt lavt kulstofholdigt austenitisk rustfrit stål。Tilføj kobber til dette niveau for at øge dets modstandsdygtighed over for stærke reducerende syrer，Især modstanden over for svovlsyre er stærkt forbedret。Det har også stærk modstandsdygtighed over for kloriderosion，Inklusive korrosion/Gap korrosion og spændingskorrosion revner。
