The invention relates to the technical field of alloy forging, in particular to a round steel alloy and a forging process. The round steel alloy comprises the following raw materials in parts by mass: 65-75 parts of carbon powder, 55-65 parts of aluminum ingot, and 45-65 parts of silicon powder. parts, chromium powder 6-9 parts, sponge titanium 25-35 parts, tungsten powder 15-17 parts, Al-Mn master alloy 20-30 parts, Al-Nb master alloy 20-30 parts, Al-Co master alloy 20- 30 parts, 20 to 30 parts of Al-Er alloy, and 15 to 19 parts of rare earth; and the forging process includes the following steps: S1. Loading the raw materials into the furnace: first put the raw materials in front of the furnace and bake for 10 to 48 hours before loading the furnace. Then check the surface quality and find any defects, which should be removed first; S2, heating and heating: the furnace is heated to 450 ℃ ~ 600 ℃, and after holding for a period of time, continue to heat up to 800 ℃. The invention can not only improve the welding performance and the welding stability of the round steel alloy during welding, but also improve the corrosion resistance in non-oxidizing medium such as dilute sulfuric acid and hydrochloric acid. |
