Product Description

About Product

DIN41Cr4/1.7035 Steel is one of the most widely used medium carbon quenched and tempered
steels in the machinery manufacturing industry as per EN10083 standard.After proper heat treatment,
it has good comprehensive mechanical properties, such as good toughness, plasticity and wear
resistance, low temperature impact toughness and low notch sensitivity.

The hardenability of 41Cr4 steel is good,which is higher than that of C45 steel.41Cr4 steel is suitable
for surface hardening such as high frequency quenching and flame quenching.After quenching and
tempering (or normalizing), good machinability can be obtained.It is usually supplied in quenched
and tempered condition

41Cr4/DIN 1.7035 STEEL APPLICATION

After quenching and tempering, 41Cr4 steel is used to manufacture mechanical parts under medium load and medium speed, such as steering knuckles, rear half shafts of automobiles, and gears, shafts, worms, spline
shafts, and top sleeves on machine tools.

• Quenching  with medium temperature tempering

Manufacture of parts subjected to high load, impact and moderate speed work, such as gears, spindles, oil pump rotors, sliders, collars, etc

• Quenching  with low temperature tempering

Manufacture of parts with heavy load, low impact and wear resistance, and the solid thickness of the section is less than 25mm, such as worm, spindle, shaft, collar, etc.

• QT &  High frequency surface hardening

Manufacture of parts with high surface hardness and wear resistance without great impact, such as gears, sleeves, shafts, main shafts, crankshafts, mandrels, pins, connecting rods, screws, nuts, intake valves, etc.

In addition, 41Cr4 steel is suitable for the manufacture of various transmission parts for carbonitriding treatment, such as gears and shafts with large diameters and good low temperature toughness.
