| 摘要 |
The invention relates to an austenitic stainless steel with improved pitting corrosion resistance and improved strength. The stainless steel contains in weight % less than 0,03 % carbon (C), 0,2 - 0,6 % silicon (Si), 1,0 - 2,0 % manganese (Mn), 19,0 - 21,0 % chromium (Cr), 7,5 - 9,5 % nickel (Ni), 0,4 - 1,4 % molybdenum (Mo), less than 1,0% copper (Cu), 0,10 - 0,25 % nitrogen (N), optionally less than 1,0 % cobalt (Co), optionally less than 0,006 % boron (B), and the rest being iron (Fe) and inevitable impurities. |
