  • Patent number: 11090627
    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.
