Engineering Alloy Tool Steel Bar 1.7035 / SAE5140 For Mechanical

 

 

Introduction:

 

Grade 1.7035 / 40Cr steel is one of the most widely used steel in the machinery industry.

It has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity.

This type of steel is suitable for cyanide and high frequency quenching.The cutting performance is better, when the hardness is 174~ 229HB, the relative cutting machinability is 60%.The steel is suitable for making medium plastic mold.

Features:

 

40Cr (SAE5140) steel is belong to Medium carbon steel with hardening and tempering, cold heading steel. Easy processing, after proper heat treament can obtain a certain toughness, plasticity and abrasion resistance.

Characteristic:

 

Grade 1.7035 is kind of medium carbon steel, cold heading die steel.The steel price is moderate and easy to process, and it can obtain certain toughness, plasticity and wear resistance after proper heat treatment.

The positive fire can promote the spheroidization and improve the cutting performance of the hardness less than 160HBS.

In the tempering temperature 550 ~ 570 ℃, the steel has the best comprehensive mechanical properties.The hardness of steel is higher than 45 steel, suitable for high frequency quenching, flame quenching and other surface hardening treatment.

 

 

Applications:

 

After hardneing & tempering, applied to use in the manufacture withstand load and moderate speeds mechancial parts, such as automotive steering knuchles, and rear axle gears, shafts, worm, spline shaft, sets and other tools on top.

 

 

Delivery condition:

 

Hot rolled or forged, black surface.
Hardenss: annealed <207HB.

 

 

40Cr shaft parts:

 

Shaft parts are one of the typical parts of the machine.It is mainly used to support transmission of zero components, transfer torque and load.

The axial parts are the rotating body parts, whose length is greater than the diameter, and are generally composed of the outer cylinder of the concentric shaft, the cone surface, the inner hole and the thread and the corresponding end surface.

According to the structural shape, the axial parts can be divided into the optical axis, the step axis, the hollow shaft and the crankshaft.

The long diameter ratio of the axis is less than 5, which is called the short axis, which is greater than 20 and is called a slender axis. Most of the axes are between the two.
