Ferritic stainless steel addition of phosphorus having excellent properties for the shaping and secondary workability.

摘要

Ferritic stainless steel consisting essentially of, in % by weight, 0.0050 to 0.0500 of C, 10.00 to 18.00 of CT, up to 0.50 of Si, up to 0.50 of Mn, more than 0.040 but not more than 0.200 of P up to 0.030 of S, up to 0.60 of Ni 0.005 to 0.200 of Sol. Al, and trace to 0.0050 of B, the balance being Fe and impurities, the C, Cr, F, Sol. Al and B content being further balanced so that the point having the % (Cr+50xP) as the abscissa and the % (C+10xB +Sol.Al) as the ordinate may fall within the area of a quadrilateral ABCD of Fig. 1.
