CPC classification number: B01J19/02 , B01J2219/0286 , B22F3/15 , C07C273/04 , C22C33/0285 , C22C38/002 , C22C38/005 , C22C38/02 , C22C38/04 , C22C38/40 , C22C38/42 , C22C38/44 , C22C38/58 , F28F21/083
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.
Abstract translation: 公开了一种热等静压型铁素体 - 奥氏体钢合金及其目的。 合金的元素组成按重量百分数计：C 0 - 0.05; Si 0-0.8; Mn 0-4.0; 铬超过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; 余量为Fe和不可避免的杂质。 这些物体在制造需要诸如机械加工或钻孔的加工的尿素生产设备的部件方面特别有用。 优选的用途是制造或替代在汽提器中使用的液体分配器，如通常存在于尿素装置的高压合成段中。
