摘要

Patent Summary: "Austenitic Stainless Steel". The present invention relates to an austenitic stainless steel which is described herein. in the described embodiments, austenitic stainless steel comprises 16.00 wt% chromium to 30.00 wt% chromium; 8.00 wt% nickel to 27.00 wt% nickel; not more than 7,00% by weight molybdenum; 0.40 wt% nitrogen to 0.70 wt% nitrogen, 1.0 wt% manganese to 4.00 wt% manganese, and less than 0.10 wt% carbon in that the ratio of manganese to nitrogen is controlled to less than or equal to 10.0. Austenitic stainless steel based on specified minimum pren (equivalent corrosion resistance) values is also described. (1) pre = wt% cr + 3.3x- wt% (mo) + 16 wt% 0.40 to 0.70 with w present. 19846807v1
