AISI 8620 Steel

 

8620 alloy steel is a kind of steel with excellent comprehensive properties. The following are its implementation standards, chemical composition range values, mechanical properties, advantages, disadvantages, and applications.

 

Implementation standards:

 

* China (GB): GB/T 3077-2015

* United States (ASTM): A29/A29M-2016

* Japan (JIS): JIS G4105-1999

 

Chemical composition range values:

 

* C: 0.17%~0.23%

* Si: 0.17%~0.37%

* Mn: 0.40%~0.60%

* P: ≤0.035%

* S: ≤0.035%

* Cr: 1.25%~1.65%

* Mo: 0.25%~0.35%

* Ni: 0.30%~0.70%

 

Mechanical properties:

 

1. Yield strength: ≥ 785 MPa

2. Tensile strength: ≥ 980 MPa

3. Elongation: ≥ 10%

4. Reduction of area: ≥ 40%

5. Impact energy: ≥ 47 J

6. Hardness: ≤ 229HBW

 

Advantages:

 

1. Good strength and toughness: 8629 alloy steel has high strength and toughness, and can obtain good comprehensive performance after proper heat treatment.

2. Good corrosion resistance: The nickel, chromium, and other elements in the alloy steel can improve its corrosion resistance and can be used in various corrosive environments.

3. Good processing performance: The processing performance of 8620 alloy steel is good, easy to cut, bend, drill and other operations, facilitating the manufacture of various parts and components. In addition, it can be welded, riveted and other operations for processing and manufacturing convenience.

4. Excellent high-temperature performance: Due to the presence of chromium, nickel and other elements in the alloy steel, its high-temperature performance is good, and it can maintain good performance under a certain high temperature environment.

5. Good fatigue resistance: The alloy steel can obtain better fatigue resistance after appropriate heat treatment, and maintain high fatigue life under repeated load conditions.

 

Disadvantages:

 

1. High price: Compared with ordinary carbon steel, the price of 8620 alloy steel is high, which may limit its application in some areas.

2. High density: The density of alloy steel is generally higher than that of carbon steel, so its weight is larger, and it may not be suitable for applications that require weight reduction.

3. Sensitive to temper brittleness: At a specific temper temperature, 8620 alloy steel may experience temper brittleness, which may affect its toughness, corrosion resistance, and high-temperature performance. Therefore, attention should be paid to the temper temperature and time during application.

 

Applications:

 

8620 alloy steel is mainly used to manufacture parts with high strength, high toughness, corrosion resistance, and high-temperature performance requirements, such as critical components in the automotive, aerospace, petrochemical, power generation industries, etc. For example, automotive gears, connecting rods, bolts, shafts and other components can be made of 8620 alloy steel. In addition, it can also be used to manufacture various special equipment such as high-pressure vessels, boilers, ocean engineering equipment, medical equipment, etc.
