Abstract
An iron alloy for tools and other purposes contains 0,15-1,6 per cent of carbon, 3,25-6 per cent of chromium, 8-20 per cent of tungsten, 1-5,6 per cent of molybdenum and up to 3 per cent of silicon, with or without up to 6 per cent of vanadium and up to 16 per cent of cobalt, and with or without small amounts of the following elements as impurities: manganese, nickel, titanium, tantalum, uranium, copper, aluminium, sulphur, phosphorus, arsenic, and tin. The molybdenum content is 12,5-28 per cent of the tungsten content. Heat treatments for hardening, tempering, carburizing, and nitrogenizing may be applied, and the tempering and nitrogenizing operations may be carried out simultaneously. Specification 411,321 is referred to.
