Abstract
1292800 Making bearing components FORD MOTOR CO Ltd 11 May 1970 [9 June 1969] 22624/70 Heading B3A [Also in Division C7] The subject-matter of this Specification is similar to that described in co-pending application 22622/70 except that the forging step is omitted. The initial austenitizing anneal is carried out on a tubular race blank above 1750‹ F., e.g. 2000‹ F., in N 2 and after air cooling is spheroidized at 1200-1550‹ F., e.g. 1395‹ F. for 2 hrs., followed by air cooling. The final tempering temperature is 250-400‹ F.
