4130 chromoly tube
4130 structural steel has high strength and toughness, high hardenability, critical hardenable diameter in oil is 15 ~ 70mm; the thermal strength of steel is also good, it has sufficient high temperature strength below 500 ℃, but at 550 ℃ Its strength decreases significantly; when the alloy element is welded at the lower limit, it is quite good, but the weldability is moderate near the upper limit, and it needs to be preheated to above 175 ° C before welding; the machinability of the steel is good, and the plasticity is moderate during cold deformation; The range of 300 ～ 350 ℃ has the first type of tempering brittleness; there is a tendency to form white spots.
AE 4130/JIS SCM430 25crmo4 1.7243 l alloy seamless steel pipe.
4130 is chromoly steel, which has high strength and toughness, high hardenability
