40CrNiMoA Alloy Steel Mechanical Properties
It was used where require high tensile and good wear-resistance property parts such as heavy-duty axles, shafts, heavy-duty gears, spindles, pins, studs, bolts, couplings, sprockets, pinions, torsion bars, connecting rods. These high tensile alloy steel has been widely used in the areas such as petrol chemical industry, automotive, steam power equipment and other high temperature services.
