<p>The compsn. is as follows: Cr 23.0-30.0%, Ni 4.0-7.0%, Mo 1.0-5.0%, Cu 1.0-4.0%, Si 0.2-2.0%, Mn 0.2-4.0% C, 0.01-0.1%, N 0.06-0.4%; the remainder Fe and impurities. The Cr, Ni and N contents are related as follows: Cr Content / Ni Content = 3.8-6.25; Ni content + 200 x N content / Cr content = 0.74-3.72 When the formulae are plotted against each other, the points lie within a quadrilateral whose coordinates are as follows: (3.8, 3.72) (6.25, 2.96) (6.25, 1.1) (3.8, 0.74).</p> |
