45Mn carbon structural steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and there is a tendency to temper brittleness. It is generally used in the quenched and tempered state, and P355GH steel density can also be used in Used in quenched and tempered or normalized state.

42CrMo alloy steel p355gh steel density: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate p355gh steel density has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts
