Abstract

Procedure for the preparation of austenitic stainless steel consisting essentially, in percent by weight, of: (see graph) and comprising the following operations: (1) collecting the constituents for an initial charge of the furnace; (2) introducing the charge into a melting furnace container; (3) heating the charge above the melting temperature to produce a molten bath in the furnace container; (4) adding additional constituents to the molten bath to adjust its composition to the desired final composition; (5) bleed the oven to remove the molten bath from the oven to a spoon; (6) casting the molten alloy from the ladle into the ingot molds in which the molten alloy solidifies; (7) separating the molds from the solidified ingots of the alloy; (8) heating the ingots to a temperature appropriate for hot work to billet form; (9) hot work the billet to the bar or rod shape from which finished products, such as valve, can be manufactured by operations such as forging followed by final machining; said steel having good resistance to corrosion, surface hardness and resistance to high temperatures, and being particularly adapted for the manufacture of valves for internal combustion engines.
