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.
