PURPOSE:To improve the hot workability and to increase the material yield by regulating the N and Si conents in a stainless steel contg. Ni and Cr as principal components so that a prescribed equation is satisfied. CONSTITUTION:An austenitic stainless steel is obtd. by regulating the Si and N contents in a stainless steel contg. Ni and Cr as principal components so that an equation Si wt.%<=-1.45XN wt.%+0.44 is satisfied. The austenitic stainless steel has superior hot workablility and can be rolled without causing external flaws, so the material yield is increased.
