Abstract (en)

[origin: EP2042616A1] Austenitic stainless rolled steel plate of a thickness of 100 mm or more, characterised by : containing, by mass%, C: 0.08% or less, N: 0.10% to 0.22%, C+N: 0.12% or more, Si: 0.01% to 2.0%, Mn: 0.1% to 2.0%, Cr: 15% to 27%, Ni: 8% to 20%, Mo: 4% or less, Co: 0.1% or less, Cu: 0.1% to 3%, Al: 0.001% to 0.10%, and Ca: 0.0005% to 0.01%, having a calculated value of the amount of ´-ferrite defined by the following (I) formula (´cal; vol%) of -7% to 4%, and having an elongation in the width direction and length direction at any location in the thickness direction of 30% or more: ´cal vol % = 2.9 × Cr + 0.3 Si + Mo - 2.6 × Ni + 0.3 × Mn + 0.25 × Cu + 35 × C + 20 × N - 18 where [element abbreviations] means the content of the element (mass%), and the elongation is the value measured at 4K.
