An austenitic stainless steel plate containing up to 0.08 wt. % of carbon, up to 1.0 wt. % of silicon, up to 2.0 wt. % of manganese, 8.0-16.0 wt. % of nickel, 16.0-20.0 wt. % of chromium, 0-30 wt. % of molybdenum, up to 0.25 wt. % of nitrogen and the balance of iron and inherent impurities, is manufactured by rolling a stainless steel blank at a temperature higher than TR( DEG C.)=940+30(%Mo), and then cooling the rolled blank from a temperature above 800 DEG C. to a temperature below 500 DEG C. at a cooling speed higher than Rc ( DEG C./sec.) shown by the following equations: log (Rc)=-0.32+14(%C+%N)-0.067(%Mo) when (%C+%N)</=1.0 wt. %; and log (Rc)=1.08-0.067(%Mo) when (%C+%N)>1.0 wt. %. |
