Abstract:
An austenitic stainless steel sheet consists, (mass %), of: C: 0.03 to 0.15%; Si: 0.20 to 2.5%; Mn: 0.2 to 4.5%; P: 0.010 to 0.030%; S: 0.0001 to 0.0010%; Cr: 20.0 to 26.0%; Ni: 10.0 to 15.0%; Cu: 0.01 to 2.0%; Mo: 0.01 to 2.0%; Co: 0.05 to 2.50%; Al: 0.01 to 0.20%; N: 0.1 to 0.6%; V: 0.02 to 0.15%; B: 0.0002 to 0.0050%; Nb: 0 to 0.10%; Ti: 0 to 0.10%; Y: 0 to 0.10%; Ca: 0 to 0.010%; Mg: 0 to 0.010%; and REM: 0 to 0.10%, balance Fe and impurities. Contents of [Mn] and [S] satisfy [Mn]×[S]≤0.0020. Sheet thickness is 0.5 mm or smaller, an aspect ratio value L1/L2 satisfies L1/L2≥1.5 where L1 and L2 denote major and minor axis lengths of a crystal grain. A surface hardness (HV) is 300 or higher after retention at 600° C. for 400 hours.

Claim (Index 5):
