Forgings factory 40Cr forgings extensive

40Cr is one of the widely used steel grades, is also commonly used forgings plant material, belongs to the alloy structure steel. 40 cr forging is the main characteristics of the forging factory after the tempering process, has the good comprehensive mechanical properties, low temperature impact toughness, and low notch sensitivity, good hardenability, oil cooling can get higher fatigue strength, water-cooled complex shaped forgings are prone to crack, plastic medium, cold bending tempered or quenched and tempered after cutting workability is good, but the weldability isn't good, easy to crack, Carburizing and high-frequency surface hardening can also be carried out.

Tongxin precision Forgings factory example: 40 cr forgings after quenched and tempered treatment used in the manufacture of medium speed, load of the forgings, such as gear, shaft, worm, spline shaft, thimble set of forging, conditioning and high-frequency surface hardening after used in the manufacture of high surface hardness, wear resistance of forging, such as gear, shaft, shaft, crankshaft, spindle, sleeve, pin, connecting rod, screw nut, inlet valve, such as forging products, After quenching and tempering temperature in forging used in the manufacture of heavy, medium speed impact, such as oil pump rotor, slider, gear, shaft, sets of ring, etc., used in the manufacture of reloading after quenching and low temperature tempering, low impact and abrasion resistance of forgings, such as worm, such as main shaft, shaft, thimble, carbonitriding place namely after manufacture large size, high low-temperature impact toughness of the transmission of forgings, Such as shaft, gear and other forging products.

So 40Cr forgings are commonly used materials in forging factory production.
