Abstract
In a process for improving the properties of iron or steel either unalloyed or alloyed but containing at least 50 per cent of iron, one or more of the elements, tantalum mobium, cerium, and uranium are included in the iron &c. in a total amount of 0,1-8 per cent and the alloy so constituted is cooled quickly or slowly from the casting temperature or in the case of reheating the alloy, from 700-1300 DEG C. and then tempered at 150-800 DEG C. When the alloy has been reheated, the alloy may be subjected to a particularly slow cooling instead of tempering. The alloy may also contain one or more of the elements silicon, manganese, nickel, chromium, tungsten, molybdenum, vanadium, and cobalt. The process is particularly applicable to stainless chromium or nickel-chromium iron or steel alloys such as those containing 6-40 per cent of chromium, 25-0,5 per cent of nickel and up to 1 per cent of carbon. Specification 29597/09, [Class 72, Iron &c.], is referred to.
