Conclusions
-
1.
The hardening of 28Kh10G8M4 steel during cold-plastic deformation is due to the formation of martensite resulting from deformation and to cold working of the austenite.
-
2.
Hot rolling at 1100°C, with subsequent cold deformation with 30% deformation and tempering at 500°C for 1 h, results in the following characteristics: σb=190–215 kg/mm2, δ=15–20%, and aH=6–8 kgm/cm2 (tested at 20°C).
