AUSTENIC STEEL

摘要

Austenitic steel contains from 0.01 to 0.04% by weight of carbon, from 21.00 to 24.00% by weight of chromium, from 0.25 to 0.65% by weight of silicon, from 0.25 to 0.70% by weight of manganese, from 1.00 to 1.40% by weight of nitrogen, the balance being iron, the total content of ferrite-forming components in the steel, namely, of silicon and chromium, and the total content of austenite-forming components therein, namely, of carbon, nitrogen and manganese, obeying the following condition: 0.48ÄSiÜ+ÄCrÜ DIVIDED 30ÄCÜ+18ÄNÜ+0.01ÄMnÜ = from 0.8 to 1.3, where ÄSiÜ, ÄCrÜ, ÄCÜ, ÄNÜ, ÄMnÜ is the content in the steel of silicon, chromium, carbon, nitrogen, and manganese, respectively, expressed in % by weight.
