| description | The invention discloses stainless steel for a pump head body. The stainless steel comprises the following raw materials: less than or equal to 0.04% of C, less than or equal to 0.60% of Si, 0.50-1.00% of Mn, less than or equal to 0.008% of S, less than or equal to 0.010% of P, 14.00-16.00% of Cr, 3.50-5.50% of Ni, 1.50-2.00% of Mo, 0.14-0.20% of N, 0.20-0.40% of Cu, 0.20-0.40% of Ti, and the balance Fe and inevitable impurities. The invention further discloses a preparation method of the stainless steel. According to the preparation method, the chemical components of the stainless steel are screened and optimized, and a reasonable smelting and forging mode and a heat treatment process are sought for the stainless steel, so that the stainless steel with high strength and hardness, excellent impact toughness, good corrosion resistance and low alloy cost is finally obtained, and the requirements of pump head body materials of a large intelligent mine emulsion pump station are met.
