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; |
| 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; |
