Abstract

553,397. Iron alloys. BRITISH PISTON RING CO., Ltd., TWIGGER, T. R., and JUDD, J. A. March 9, 1942, No. 3035. [Class 82 (i)] [Also in Group XXII] Valve and similar guides are produced by pressing and sintering operations from highly alloyed iron of such composition that the structure is austenitic and has a co-efficient of expansion exceding 0.000016 per degree C. The composition of the powder is such that the percentage of total carbon is from 0 to 5, silicon 0 to 5, nickel 8 to 25. chromium 0 to 5, copper 0 to 10, manganese 0 to 10, molybdenum 0 to 5 and the remainder iron. Vanadium, titanium, tungsten, aluminium or cobalt up to 5 per cent. each may be added. The powder is consolidated in a die and the compact produced is sintered at 1100‹C., repressed as closely as possible to finished dimensions, and may be finished by normalising and machining. To ensure full austenitic structure the guides may be quenched from about 500‹C. and the outer layers may be carbonized or nitrogen hardened, and the guides may be impregnated with oil.
