4140 alloy steel forgings advantages：
4140 steel forgings are alloy steel forgings containing high levels of chromium and molybdenum. 4140 alloy steel forgings have the characteristics of high strength, good hardenability, good toughness, and small deformation during quenching.
High strength
The strength of 4140 steel forgings belongs to high-strength alloy steel forgings, with high yield strength and high tensile strength.
Good hardenability
After quenching, 4140 steel has good hardenability and can meet the requirements of cooling rate.
Good toughness:
4140 steel forgings have good toughness, can withstand large impact loads, and are not prone to cracks.
Small deformation during quenching:
4140 steel forgings have little deformation during the quenching process and can be used to manufacture parts requiring high dimensional accuracy.
High high-temperature creep strength and endurance strength:
4140 steel forgings have good strength and endurance performance at high temperatures.
shaft forgings advantages:
Forged shafts have multiple advantages such as high strength, high stability, good wear resistance, excellent overload capacity, low cost, environmental protection and energy saving. They are a good mechanical transmission element and deserve wide application.
1. High strength
One of the major advantages of forged shafts is their high strength, which is determined by the characteristics of the forging process. The metal material of the forged shaft is forged and compressed at high temperature, and its grain structure is more compact, thus achieving higher strength and toughness than other processing methods.
2. High stability
The stability of the forged shaft is also one of its advantages. During the manufacturing process of the forged shaft, the overall structure of the shaft is made tighter by forging and extruding the metal material, reducing the cracks and defects of the internal organization, thereby improving the stability and durability of the shaft.
3. Good wear resistance
The surface of the forged shaft has good wear resistance and corrosion resistance after forging, quenching and other treatment processes, and can still maintain good durability after long-term use.
4. Excellent overload capacity
Another major advantage of the forged shaft is its excellent overload capacity. On the basis of high strength, high wear resistance and high stability, forged shafts also have the ability to withstand high pressure and overload, and can play a greater role under special working conditions.
5. Low cost
Because the forged shaft adopts the forging process, its cost is relatively low compared with other manufacturing methods, which can achieve a certain degree of cost saving effect.
