What is the equivalent of en24 steel?

At most work environment, EN24 is equivalent to 40CrNiMo, 1.6511 36CrNiMo4, SNCM439, 4340 steel. Related Specifications ASTM A29/A29M DIN EN 10083/3 JIS G4053 GB GB/T 3077


What is 40Cr steel?

40Cr steel is a kind of Chinese GB standard alloy steel for engineering and machinery purpose, and one of the most widely used steel grades. For 40Cr material hardness, specifications and equivalent, please see the table below.

Is 40Cr steel good?

After quenching and tempering treatment, 40Cr steel has good comprehensive mechanical properties , low temperature impact toughness, low notch sensitivity, good hardenability, and high fatigue strength in cold oil. When water cooling, the complicated shape of the parts is prone to cracks, the cold bending plasticity is medium, and the cutting workability after normalizing is good, but the weldability is poor, should be preheated before welding, and is generally used in the state of quenching and tempering.

What is EN24 steel?

ASTM EN24 steel is an alloy structural steel , EN24 is used for engineering structural, Used as require good toughness, high strength, as well as the important conditioning of large size, heavy machinery such as high load of axial, turbine shaft, larger than 250 mm in diameter of helicopter rotor shaft, turbojet engine turbine shaft, blade, high load of transmission parts, fasteners of the crankshaft. Gear, etc.; Can also be used for operating temperature over 400 ℃ of rotor shaft and blade, etc.; And after nitriding processing can also be used to make special performance requirements of the important parts, after low temperature tempering or can be used for ultra-high strength steel after isothermal quenching
