Abstract (en)

[origin: EP3239341A1] Austenitic stainless steels excellent in flexibility are disclosed. The austenitic stainless steel excellent in flexibility according to the present invention is characterized by comprising, by weight percent, 0.1 to 0.65% of Si, 1.0 to 3.0% of Mn, 6.5 to 10.0% of Ni, 16.5 to 18.5% of Cr, 6.0% or less of Cu (excluding 0), 0.13% or less of (C + N) (excluding 0), and the remainder comprising Fe and unavoidable impurities, wherein the work hardening formula H1 defined by the following formula is 300 or less. H 1 = ˆ’ 459 + 79.8 Si ˆ’ 10.2 Mn ˆ’ 8.16 Ni + 48.0 Cr ˆ’ 13.2 Cu + 623 C + N
