摘要
A method for the manufacture of steel products and products thus produced, wherein steel is subjected to precipitation hardening in a martensitic structure subsequent to soft annealing and thereafter shaping. The method steps include shaping followed by solution annealing between 1200° C. and 1050° C., quenching from the solution annealing temperature with a quenching speed of at least 5° C. per second to a temperature below 500° C., subjecting said steel to an isothermal martensitic transformation and subsequently hardening the steel at a temperature between 450° C. and 550° C. to precipitate particles out from solution into said martensitic structure.
