Zusammenfassung:	The application relates to the technology of producing three-dimensional articles by means of powder-based additive manufacturing, such as selective laser melting (SLM) or electron beam melting (EBM). Especially, it refers to a Nickel-base superalloy powder on basis of Hastelloy X consisting of the following chemical composition (in wt. -%): 20.5-23.0 Cr, 17.0-20.0 Fe, 8.0-10.0 Mo, 0.50-2.50 Co, 0.20-1.00 W, 0.04-0.10 C, 0-0.5 Si, 0-0.5 Mn, 0-0.008 B, remainder Ni and unavoidable residual elements and wherein the powder has a powder size distribution between 10 and 100 miu and a spherical morphology and the ratio of the content (in wt.-%) of alloying elements C/B is at least 5 or more. 本发明公开了用于基于粉末的制造方法的高温镍基高温合金。本申请涉及通过基于粉末的增材制造，如选择性激光熔化(SLM)或电子束熔化(EBM)生产三维制品的技术。其尤其涉及基于哈氏合金X的由以下化学组成构成的镍基高温合金粉末(以wt.-％计)：20.5-23.0Cr、17.0-20.0Fe、8.0-10.0Mo、0.50-2.50Co、0.20-1.00W、0.04-0.10C、0-0.5Si、0-0.5Mn、0-0.008B、剩余的Ni和不可避免的残余元素，并且其中所述粉末具有10-100μm之间的粉末尺寸分布和球形形态，并且合金元素C/B含量(以wt.-％计)的比率是至少5或更大。
