Abstract:
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: C 0 - 0.05; Si 0 - 0.8; Mn 0 - 4.0; Cr more than 29 - 35; Ni 3.0 - 10; Mo 0 - 4.0; N 0.30 - 0.55; Cu 0 - 0.8; W 0 - 3.0; s 0 - 0.03; Ce 0 - 0.2; 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.
