Abstract
Austenitic noncorrodible steels containing 10-25 per cent of chromium, 5-12 per cent or more of nickel and generally low in carbon, have silicon added thereto and are heated to about 900 DEG C. and cooled quickly in air or water to globularize the carbides present. A silicon content of 0,50-6 per cent is given by way of example. The steels may also contain a small quantity of other metals such as tungsten, molybdenum, copper, titanium, vanadium. The heat treatment is said to improve the resistance to intergranular corrosive attack particularly after the steels have been heated to 500-900 DEG C. or after they have been welded. Reference has been directed by the Comptroller to Specification 298,250, [Class 72, Iron &c.].
