无磁钢40Mn18Cr3圆钢#奥氏体锰铬钢
40 mn18cr3 manganese chrome steel nonmagnetic austenitic steel protective ring, after solid solution treatment, half hot deformation strengthening and cold deformation strengthening to improve the strength of the steel, in order to meet the different protective ring category. Used for retaining rings categories Ⅰ ~ Ⅲ turbo generator without magnetic ring forgings and other requirements of magnetic components. 40 mn18cr3 no magnet steel, according to the material can be divided into 20 mn23alv 45 mn17al3, 30, 50 mn18cr4v mn20al3, 340 mn18cr4v, and without the magnetic steel is widely used in large and medium-sized transformers, electromagnet, structure without magnetic materials, etc. No magnetic steel are 7 fe, mn, al, c series austenitic, chemical composition to electromagnetic performance, organizational stability, good mechanical properties, low permeability and high resistivity, in small eddy current loss in magnetic eight games. In the magnetic field strength of 16000 a/m (oster 200), no magnetic permeability of magnetic steel mu 1.319 x 10-6 h/m or less (1.05 high/the 8), the magnetic permeability of stainless steel u = 1.339 x 10-6 h/m (1.1 high/Mr). Austenitic stainless steel after cold working with slightly magnetic.
40Mn18Cr3锰铬钢无磁性奥氏体护环钢,固溶处理后,进行半热变形强化或冷变形强化来提高钢的强度,以满足不同护环类别.用于护环类别Ⅰ～Ⅲ类的汽轮发电机无磁性护环锻件及其他要求无磁性的零部件.
40Mn18Cr3无磁钢，按照材质可分 20mn23alv、45mn17al3、30mn20al3、 340mn18cr4v、50mn18cr4v等各种无磁钢，广泛应用于大中型变压器、电磁铁、等无磁结构材料。无磁钢属7fe—mn—al—c系列奥氏体，化学成份决定电磁性能，组织稳定，力学性能优良，磁导率低而电阻率高，在磁8场中的涡流损耗极小。在磁场强度为16000a/m(200奥斯特)时，无磁钢的磁导率μ≤1.319×10-6 h/m (1.05高/奥8)，不锈钢的磁导率μ=1.339×10-6h/m(1.1高/奥)。奥氏体不锈钢经冷加工后具有轻度磁性.
