| Abstract: | The invention relates to a process for producing low alloy steel comprising the steps of: casting a steel alloy with composition 0.10 to 0.25 - carbon, 1.0 – 1.8 Manganese, 0.40 – 0.6 Silicon, 0.15 – 0.25 Chromium, 0.10 – 0.15 Molybdenum, 0.40 – 0.65 Nickel, 0.34 – 0.69 Carbon equivalent, 0 – 0.01 Vanadium, 0 -0.08 Titanium, 0 – 0.01 Boron, balance being Iron and residual impurities (in wt.%); homogenizing the steel alloy by austenitizing at 1150-1200°C for 30-45 minutes; and direct by water quenching to room temperature. |
