The elementary composition of a Hot Isostatic Pressed ferritic-austenitic steel alloy includes, in percentages by weight:

Corrosion resistant duplex steel alloy, objects made thereof, and method of making the alloy

Disclosed is a Hot Isostatic Pressed ferritic-austenitic steel alloy, as well objects thereof. The elementary composition of the alloy comprises, in percentages by weight: the balance being Fe and unavoidable impurities. The objects can be particularly useful in making components for a urea production plant that require processing such as machining or drilling. A preferred use is in making, or replacing, liquid distributors as used in a stripper as is typically present in the high-pressure synthesis section of a urea plant.
