Product Description

Material 4130 | Material 4130 Steel | High Hardenability Material 4130 Steel Bar

4130 structural steel has high strength and toughness, high hardenability, and the critical hardenable diameter in oil is 15-70mm; the hot strength of steel is also good, with sufficient high temperature strength below 500 °C, but at 550 °C Its strength decreases significantly; when the alloying elements are at the lower limit, the welding is quite good, but when the alloying element is close to the upper limit, the weldability is moderate, and it needs to be preheated to above 175 ℃ before welding; the machinability of the steel is good, and the plasticity is moderate during cold deformation; The range of 300 to 350°C has the first type of temper brittleness; there is a tendency to form white spots.
