摘要	In order to study the role of P in super ferri tic stainless steel, based on the composition of S44660 steel, the mass fraction of P was adjusted, and the P content was controlled as 0.004wt%, 0.009wt%, 0.033wt% and 0.055wt%. The effect of P content change on the microstructure and mechanical properties of cast S44660 super ferritic stainless steel was studied. The results show that P can expand the crystallization temperature range (Delta T), reduce the grain size and increase the equiaxed crystal rate when the P content is 0.009wt% and 0.033wt%. But when the P content is 0.055wt%, the grain size increases and the equiaxed crystal rate decreases. The appropriate amount of material. On the one hand, P has a refinement effect on the grain, thereby improving the impact absorption work of the material; on the other hand, excess P will promote its deflection at grain boundaries, which in turn affects the toughness of the material.
