Abstract

Surgical and dental instruments including sewing and other needles are made from quenched and tempered alloys containing 0.3-3 per cent of beryllium and at least 40 per cent of nickel. The alloys may also contain up to 25 per cent of iron, 10-25 per cent of chromium, up to 12 per cent of molybdenum, and up to 18 per cent of tungsten, with or without small additions of other elements. The instruments are preferably heated and quenched before coldworking to their final dimensions, and tempered after coldworking. The alloys may be quenched from 800-1100 DEG C. and tempered at 350-650 DEG C.
