40Mn18Cr3无磁钢#硬质模具钢40Mn18Cr3钢板
40 mn18cr3 manganese chrome nonmagnetic austenitic steel protective ring, after solid solution treatment, half hot deformation strengthening and cold deformation strengthening to improve the strength of steel, to meet different protector category. Used for retaining rings categories Ⅰ ~ Ⅲ turbo generator without magnetic ring forgings and other requirements of magnetic components. A 40 mn18cr3 is no magnet steel, according to the material can be divided into 20 mn23alv 45 mn17al3, mn20al3 30, 40, 50 mn18cr4v mn18cr3, 340 mn18cr4v, and no 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.
