Product description
ASTM 4140 4130 30Crmo 42Crmo steel plate hot rolled steel sheet alloy steel plate
4130 structural steel has high strength and toughness, higher hardenability, critical quenching diameter in the oil 15 ~ 70mm; The thermal strength of steel is also good, with sufficient high temperature strength below 500℃, but the strength decreases significantly at 550℃. When alloying elements at the lower limit welding is quite good, but close to the upper limit welding performance is medium, and need to preheat to 175℃ before welding; The steel has good machinability and medium plasticity during cold deformation. The first kind of tempering brittleness in the range of 300 ~ 350℃ during heat treatment; Tendency to form white spots.

Our advantage
In 2019, In order to meet the processing request of more customers, we have added three new machining center divisions, first one is 5000W laser machining center, which can cut and bend according to customer's size, sandblasting machining center, painting processing center, With high quality products and top after-sales service.
Application
This type of steel is usually used in the tempered state, when the carbon content of the lower limit of steel can also be used for higher core strength of carburizing steel. In the medium machinery manufacturing industry is mainly used for manufacturing large section, in high stress conditions of the work of tempering parts, such as shaft, spindle and high load control wheel, bolts, bolts, gears, etc.; In the chemical industry for the manufacture of welding parts, plates and pipes composed of welding structure and in the nitrogen hydrogen medium working temperature does not exceed 250℃ high pressure conduit; In the steam turbine and boiler manufacturing industry for the manufacture of fasteners under 450℃, under 500℃ high pressure flanges.
