Abstract

1318887 Carburizing and nitriding steel JOSEPH LUCAS (INDUSTRIES) Ltd 23 Sept 1970 [31 Oct 1969] 53458/69 Heading C7U [Also in Division B3] The strength of an extruded, low carbon non- alloyed steel is increased by heating it in an atmosphere containing 0À4-0À8% by volume of carbon and 0À15-0À4% by volume of nitrogen to cause carbon and nitrogen to diffuse into it. In an example, an extruded steel is heated at 850-1000‹C. for 8-24 hrs to increase the tensile strength of the steel to 100 t. s.i. The atmosphere may also contain nickel, chromium, boron and manganese.
