8620 Steel vs 4620 – What’s the Difference

8620 Steel vs 4620

Steel is an alloy widely used in various industries because of its strength, durability, and versatility. However, there are numerous types of steel, and every one of them carries unique characteristics and properties. Two popular types of steel are the 8620 and 4620 steels. In this blog post, we’ll compare the two and see which is better regarding strengths, applications, and differences.

Difference Between 8620 and 4620

8620 and 4620 steel are low-carbon alloy steels containing chromium, molybdenum, and nickel. 8620 steel is a carburizing steel with a higher carbon content than 4620 steel, making it stronger and harder. However, 4620 steel is more ductile and weldable than 8620 steel.


8620 steel and 4620 steel have good strength and toughness properties, as well as good weldability and machinability. 8620 steel is stronger and harder than 4620 steel due to its higher carbon content. However, 4620 steel is more ductile and weldable.


8620 steel is typically used for gears, shafts, forgings, and fasteners. 4620 steel is typically used for axles, connecting rods, and crankshafts.


The main advantages of 8620 steel over 4620 steel are its strength and hardness. The main advantages of 4620 steel over 8620 steel are its weldability and ductility.


The main disadvantages of 8620 steel compared to 4620 steel are its lower weldability and ductility. The main disadvantage of 4620 steel compared to 8620 steel is its lower strength and hardness.


In conclusion, both 8620 steel and 4620 steel are low alloy steels with different properties and applications. The choice between the two depends on the intended use and application requirements. 8620 steel is an excellent option for applications that require high wear resistance and shock absorption, while 4620 steel is a great choice for projects that require high fatigue resistance and endurance. As a manufacturer or a buyer, understanding which steel suits your project’s requirements is essential in achieving high-quality production and manufacturing.
