4130 alloy steel plate Description
What is 4130 alloy steel plate
4130 structural steel has high strength and toughness, high hardenability, critical quench diameter in oil 15 ~ 70mm; The thermal strength of steel is also good. It has sufficient 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 close to the upper limit, the weldability is medium, and before welding should be preheated to more than 175℃; The steel has good machinability and medium plasticity during cold deformation. The first type of temper brittleness occurs in the range of 300 ~ 350℃ during heat treatment. Tends to form white spots.
4130 alloy steel plate application
This steel is usually used in the tempered state, when the carbon content of the lower limit of steel can also be used as a higher core strength of the carburized steel. In the medium machinery manufacturing industry is mainly used to manufacture large section, under high stress conditions of tempering parts, such as shaft, spindle and high load control wheel, bolt, bolt, gear, etc. In the chemical industry used to manufacture welding parts, plate and pipe composed of welding structure and in the medium containing nitrogen and hydrogen working temperature does not exceed 250℃ high pressure conduit; In the steam turbine, boiler manufacturing industry for the manufacture of fasteners below 450℃, 500℃ under high pressure flange and flange cover.
