METHOD FOR PRODUCING MARTENSITIC STEEL WITH MIXED HARDENING |
摘要 |
The invention relates to a method for producing martensitic steel that comprises a content of other metals such that the steel can be hardened by an intermetallic compound and carbide precipitation, with an Al content of between 0.4% and 3%. The heat shaping temperature for the last heat shaping pass of said steel is less than the solubility temperature of the aluminum nitrides in said steel, and the heat treatment temperature for each optional heat treatment after said last heat shaping pass is less than the solid-state solubility temperature of the aluminum nitrides in said steel. |
