Abstract

Przedmiotem zgłoszenia jest sposób obróbki cieplno-plastycznej stali martenzytycznej z filmami austenitu szczątkowego, prowadzony poprzez austenityzowanie, kucie na gorąco i chłodzenie, który charakteryzuje się tym, że wsad o składzie 0,15% - 0,2% mas. C, 3,8% - 4,5% mas. Mn, Al i Si, których sumaryczne stężenie wag. nie przekracza 2%, 0,2% - 0,3% mas. Mo, Ti w ilości 0,03% - 0,04% mas., V w ilości 0,06% - 0,08% mas., a resztę stanowi Fe, austenityzuje się w temperaturze 1100°C - 1150°C, następnie kuje na gorąco w temperaturze 950°C - 980°C podczas ostatniego odkształcenia zadanego poprzez kucie, następnie chłodzi ze średnią szybkością chłodzenia odkuwki w zakresie 50 — 2°C/s do temperatury hartowania niezupełnego wynoszącej 260°C - 280°C i następnie nagrzewa do temperatury 400°C - 450°C, po czym wygrzewa w niej przez 300s, następnie chłodzi na powietrzu do temperatury pokojowej.The subject of the application is a method of thermoplastic treatment of martensitic steel with retained austenite films, carried out by austenitizing, hot forging and cooling, which is characterized in that the charge with the composition of 0.15% - 0.2% by weight of C, 3.8% - 4.5% by weight of Mn, Al and Si, the total weight concentration of which does not exceed 2%, 0.2% - 0.3% by weight of Mo, Ti in the amount of 0.03% - 0.04% by mass, V in the amount of 0.06% - 0.08% by mass, and the rest is Fe, are austenitized at a temperature of 1100°C - 1150°C, then hot forged at a temperature of 950°C - 980°C during the last deformation imposed by forging, then cooled at an average cooling rate of the forging in the range of 50 - 2°C/s to the partial hardening temperature of 260°C - 280°C and then heated to a temperature of 400°C - 450°C, then soaked there for 300s, then cooled in air to room temperature.
