Abstract

1. The use of a molybdenum-free chromium-containing alloy consisting of 21 to 35 % by weight chromium, 30 to 70 % by weight iron, 2 to 40 % by weight nickel, 0 to 20 % by weight manganese, an typical accompanying elements, such as carbon, silicon, phosphorus, sulfur, nitrogen, aluminium, copper, vanadium, titanium, tantalum and niobium, as a material for articles which are resistant to sulfuric acid having a concentration of more than 96 %.
