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