Abstract

PURPOSE: To perfectly prevent the generation of the stringer flaw, by restricting the concentration product of Ti and N in the SUS321 steel.
CONSTITUTION: By wt%, C≤0.08%, Si≤1.00%, Mn≤2.00%, P≤0.040%, S≤ 0.030%, 9.00%≤Ni≤13.00%, 17.00%≤Cr≤19.00%, and Ti≥C×5%, and the balance Fe; besides, Ti×N≤0.002. The generation of the tringer flaw is almost perfectly prevented, and the excellent surface condition of the product can be obtained. The line B in the diagram shows the line of Ti×N=0.003, and the stringer flaw does not generate under the line A showing Ti×N≤0.002. The manufacturing cost according to this method, does not show any special increase. The management of operation is easy.
