AISI4130 Alloy Structural Steel 6.0mm-1200mm Very High Strength And Toughness

4130 structural steel has high strength and toughness, high hardenability, and the critical hardenability diameter in oil is 15-70mm; The thermal strength of steel is also good, and it has enough high temperature strength below 500 ℃, but its strength decreases significantly at 550 ℃; When the alloy element is at the lower limit, the welding is quite good, but when it is close to the upper limit, the weldability is medium, and it needs to be preheated to above 175 ℃ before welding; The steel has good machinability and medium plasticity during cold deformation; There is the first type of temper brittleness in the range of 300~350 ℃ during heat treatment; There is a tendency to form white spots.
