Abstract

Nickel, chromium and alloys containing nickel or chromium or both in a total amount of at least 8 per cent, are treated with an aqueous solution of oxalic acid, ferric oxalate and a compatible chloride. Sodium, potassium, lithium, ammonium, magnesium, tin, vanadium, manganese, iron, cobalt, chromium and nickel chlorides may be used and some hydrochloric acid may be added. The ferric oxalate may be formed in the solution by oxidation of ferrous oxalate, preferably by means of sodium chlorate. The treatment of an alloy containing 26 per cent chromium, 3 per cent aluminium and 71 per cent iron is referred to. After treatment, with or without subsequent liming, the metal or alloy may be subjected to plastic deformation, e.g. drawing. Specification 455,077 is referred to.
