Abstract
High chromium stainless steels having enhanced corrosion resistance are provided in which the steels have 25% to 35% by weight chromium; 0.1 to 5% by weight molybdenum; 0.1 to 6% by weight nickel; 0.0 to 4% by weight copper; 0.0 to 1% by weight titanium and/or niobium and/or vanadium; and, 0.02 to 5% by weight of a platinum group metal. The steels are particularly resistant to sulphuric and phosphoric acids.
