Abstract (en)
[origin: EP1431408A1] An austenitic stainless steel includes (a) 0.03wt% to 0.12wt% of C, (b) 0.2wt% to 1.0wt% of Si, (c) 7.5wt% to 10.5wt% of Mn, (d) 14.0wt% to 16.0wt% of Cr, (e) 1.0wt% to 5.0wt% of Ni, (f) 0.04wt% to 0.25wt% of N, (g) 1.0wt% to 3.5wt% of Cu, (h) trace amount of Mo, and the balance being Fe and incidental impurities. The austenitic stainless steel has a delta - ferrite content less than 8.5 and equal to 6.77Ä(d)+(h)+1.5(b)Ü-4.85Ä(e)+30(a)+30(f)+0.5(c)+0.3(g)Ü-52.75. <IMAGE>
