Product Description

Mechanical Hot Rolled Special Alloy Steel Plate SAE5140 1.7035 SCR440 40Cr

1,Chemical composition(%):

C	Si	Mn	S	P	Cr	Ni	Cu
0.37-0.44	0.17-0.37	0.70-0.90	<=0.040	<=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,Delivery condition:
 Hot rolled or forged/ peeled or black surface/annealed or Q+T.
 
6,Delivery time:
For abundant stock, 15-20 days.
For customized products, 30-50 days.

7,Our service:

1)	Sizes, materials and others are all at your requirements and can be changed;
