Electromagnetic and Mechanical Performance
-
Estructura austenítica estable: Remains non-magnetic even after processing.
-
Low Permeability: En 16,000 Soy (200 Oersted), permeabilidad magnética (metro) is ≤ 1.319 × 10⁻⁶ H/m—lower than that of standard stainless steel (metro ≈ 1.339 × 10⁻⁶ H/m).
-
Minimal Eddy Current Losses: Ideal for high-efficiency electromagnetic systems.
-
Alta resistencia: Achieved through solution treatment, semi-hot deformation, or cold working processes.
Applications of 40Mn18Cr3 Non-Magnetic Steel
40Mn18Cr3 is commonly used as non-magnetic retaining ring steel in Class I to Class III turbine generator retaining rings, as well as other critical non-magnetic components. It is designed to meet stringent performance requirements in high-intensity magnetic fields without losing structural integrity.
