FERRITE-AUSTENITE STAINLESS STEEL SHEET EXCELLENT IN RIDGING RESISTANCE AND WORKABILITY AND PROCESS FOR MANUFACTURING THE SAME |
摘要 |
This ferrite-austenite stainless steel sheet includes: in terms of mass%, C: 0.1 % or less; Cr: 17 to 25%; Si: 1% or less; Mn: 3.7% or less; Ni: 0.6 to 3%; Cu: 0.1 to 3%; and N: 0.06% or more and less than 0.15%, with the remainder being Fe and inevitable impurities, wherein the steel sheet has a two-phase structure consisting of a ferrite phase and an austenite phase, a volume fraction of the austenite phase is in a range of 15 to 70%, and in a sheet plane (ND) of a center of a sheet thickness, grains of the ferrite phase having a crystal orientation satisfying ND//{111}±10° and grains of the ferrite phase having a crystal orientation satisfying ND//{101}±10° are present in a total content of 10% by area or more. |
