A substantially non-porous, austenitic stainless steel that is resistant to chloride pitting and sulfuric acid and a method for making it are disclosed. The steel includes from 21-45% manganese, from 10-30% chromium, from 0.85-3% nitrogen, from 0-1% carbon, from 0-2% silicon, and at least two elemen
A substantially non-porous, austenitic stainless steel that is resistant to chloride pitting and sulfuric acid and a method for making it are disclosed. The steel includes from 21-45% manganese, from 10-30% chromium, from 0.85-3% nitrogen, from 0-1% carbon, from 0-2% silicon, and at least two elements selected from 1-3% copper, 1-4% nickel and 1-4% molybdenum with the combined weight of copper, nickel and molybdenum not exceeding 5% of the composition, and the balance iron and residuals, wherein the composition is such that: [Figure] (1) [Figure] (2) The steel is cast and worked to avoid a dwell period in the temperature range of 1000°-1600°F.
