| description | The invention provides spray-formed corrosion-resistant precipitation-hardened high-speed steel. The spray-formed corrosion-resistant precipitation-hardened high-speed steel comprises the following chemical components in percentage by mass: 0.5-1.2% of Si; 2.0% to 15.0% of Cr, 10.0% to 25.0% of Co; 0%-9.0% of W; mo: 5.5% to 18.0%; (Mo + W/2): 10.0%-20.0%; the steel mainly comprises an iron-based cubic solid solution matrix and an intermetallic compound (IMC for short) mu phase in the matrix, and the mu phase is (Fe, Co) 7 (Mo + W/2) 6 type. The spray-formed precipitation-hardened high-speed steel prepared by the method is small in mu phase size and uniform in distribution, has excellent comprehensive performance, particularly has outstanding corrosion resistance and tempering softening resistance, and meets the requirements of different working conditions. Compared with a powder metallurgy process, the spray forming process has the advantages of low cost and fast flow.
