Hot Rolled Annealed Steel Round bar SAE5140 / 40Cr For Machinery Manufacturing

 

SAE5140 / 40Cr is China's standard steel GB, this steel is one of the most widely used steel manufacturing machinery.

 

After quenching and tempering has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity.

 

Good hardenability of steel, water quenching can be hardened to Ф28 ~ 60mm, oil quenching can be hardened to Ф15 ~ 40mm. In addition to quenching and tempering of this steel is also suitable for cyanidation and high-frequency quenching.

 

Cutting performance is better, when the hardness of 174 ~ 229HB, the relative cutting of 60%. The steel suitable for making medium-sized plastic mold.

 

 

1, Chemical composition(%):

 

C Si Mn S P Cr Ni Cu
0.37-0.44 0.17-0.37 0.50-0.80 ≤0.035 ≤0.035 0.80-1.10 ≤0.30 ≤0.30


 

2, Application:


ASTM5140 is the most commonly used alloy structural steel, tensile strength, yield strength and hardenability are higher than the 40 steel, but the weldability is limited, there is a tendency to crack.
ASTM5140 is used for more important quenching and tempering parts, such as parts under variable load, medium speed and medium load.

 


3, Properties:

 

1) 5140 is medium carbon tempered steel, cold heading die steel;
2) The steel is moderate in price and easy to process. It can obtain a certain toughness, plasticity and wear resistance after proper heat treatment;
3) Normalizing can promote the spheroidization, improve the cutting performance of hardness less than 160HBS of blank;
4) The steel has the best comprehensive mechanical properties at the temperature of 550~570;
5) The steel is a high degree of quenching, suitable for high frequency quenching, flame hardening and other surface hardening treatment.


 

4, Heat treatment specification:


Quenching 850 degree, oil cooling;
Tempering at 520 degrees C, water cooling, oil cooling.

 

 

5, Features

 

1) Medium carbon quenched and tempered steel, cold heading steel.

 

2) The steel price is moderate, easy processing, after appropriate heat treatment to obtain a certain degree of toughness, ductility and wear resistance.

 

3) Normalizing can promote the organization of the ball, improve the hardness of less than 160HBS rough cutting performance.

 

4) Temperatures 550 ~ 570 ℃ for tempering, the steel has the best overall mechanical properties.

 

5) The steel hardenability higher than 45 steel, suitable for high-frequency quenching, flame hardening and other surface hardening treatment.


 

6, Delivery condition:


Hot rolled or forged/ peeled or black surface/annealed or Q+T.

 

7, Delivery time:


For abundant stock, 15-20 days.
For customized products, 30-50 days.


 

8, Our service:

 

1) Sizes, materials and others are all at your requirements and can be changed;
2) Price varies on materials, dimensions, finish craft and different payments;
3) We are direct manufacture in machinery manufacturing work with experience of several decades;
4) Detail production design will be made according to information you offered;
5) We have adequate inventory, so that we can quick delivery;
6) The most impotant thing is that we have advanced equipment.
