摘要: This invention relates to alloys resistant corrosion, and especially corrosion caused by contact with hot sulfuric acid of over 98% concentration. The the consist essentially weight percentages from about 19% 30% Ni, 27% Cr, 0.3% 1.0% Mo, 2.7% 4.5% Cu, 4.7% Mn, 2.45% 5.5% Si, up 0.08% C weight, balance iron. may optionally contain 0.7% Cb partially replaced 1% Ta, 0.6% W, 0.12% N 0.8% Co, all weight.
