Is non-magnetic steel the best steel?
Non-magnetic steel refers to the steel with mild magnetism, the requirement of magnetic permeability μ ≤ 1.319 × 10-6 h/m, electric furnace 20mn23alv non-magnetic steel plate, widely used in large and medium-sized transformers, electromagnets, and other non-magnetic structural materials.
Non-magnetic steel 20Mn23AlV hot rolled steel plate, 20Mn23AlV is high manganese and low magnetic steel, mainly used in coastal degaussing stations, electromagnetic suction cups, minesweepers, submarines, anti-flammable materials.
Status of supply: normalized + tempered + shot peened steel plate, hot rolled + shot peened steel plate.
Non-magnetic steel 30Mn20Al3 Baosteel/TISCO/Heavy Special<electric furnace + furnace refining>
Non-magnetic steel 40Mn18Cr3 is a manganese-chromium system of non-magnetic austenitic ring guard steel, solid solution treatment, semi-hot deformation strengthening or cold deformation strengthening to improve the strength of the steel in order to meet the different categories of ring guards of the intensity of the requirements. Used for ring guard category Ⅰ ~ Ⅲ class of turbine generator non-magnetic ring guard forgings and other requirements of non-magnetic parts.
Non-magnetic steel 40Mn18Cr4V: Baosteel/TISCO/Heavy Special<EAF+OF>
Non-magnetic steel 45Mn17Al3(917): Baosteel/TISCO/Heavy Special<EAF+OF>
Non-magnetic steel 50Mn18Cr5 is a typical and commonly used manganese-chromium non-magnetic austenitic steel. ring guard steel. After solid solution treatment, semi-hot deformation strengthening or cold deformation strengthening is carried out to increase the strength of the steel to meet the strength requirements of different ring guard categories. Used as non-magnetic ring forgings for turbine generators and other parts requiring non-magnetic properties.
