Product Details

4130 Seamless Alloy Steel Tube has high strength, high toughness, high hardenability.The critical hardenability diameter in oil is 15~70mm. The thermal strength of steel is good, with sufficient high temperature strength below 500℃, but at 550℃ Its strength is significantly reduced. When the alloy element is at the lower limit, the welding is quite good, but when the alloy element 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. The range of 300~350℃ has the first type of temper brittleness.

The outer diameter of hot-rolled seamless pipe is generally greater than 32mm and the wall thickness is 2.5-200mm. The outer diameter of cold-rolled seamless steel pipe can reach 6mm and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipe can reach 5mm and the wall thickness is less than 0.25mm. Rolling has higher dimensional accuracy than hot rolling
