The effects of electromagnetic centrifugal casting on the microstructure and properties of 0Cr1 7Mn1 4Mo2N duplex stainless steel were analyzed. The results show that the suitable magnetic induction can promote the transformation of ferrite in as-cast microstructure from long strip As a result, the plasticity of 0Cr1 7Mn1 4Mo2N is greatly improved. However, when the magnetic field induced strength exceeds 0 0 8T, the centrifugal pressure drops too much and the residual ferrite becomes small and the dispersion distribution leads to plastic deformation of 0Cr1 7Mn1 4Mo2N. , The use of electromagnetic centrifugal billet direct cold deformation successfully produced 0Cr1 7Mn1 4Mo2N seamless pipe ·
