Product Description
SAE5140/1.7035/SCR440/40Cr Alloy Tool Steel Flat Bar For Machanical
 
1,Chemical composition(%):
CSiMnSPCrNiCu
0.37-0.440.17-0.370.70-0.90<=0.040<=0.0350.80-1.10<=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 at 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: 15-20days
For customized products: 30-50days.

All the sizes as require can be customerized as fresh production with MOQ,products of required specifications can be developed/produced per international, chinese or industry standards, or based on agreements with customers.
