Question 1

What materials make up SAE 8620 alloy steel?

Accepted Answer

SAE 8620 alloy steel is composed of a blend of nickel, chromium, and molybdenum, with a low carbon content. This combination enhances its case hardenability and core toughness, making it ideal for components that require both a hard exterior and a ductile interior.

Question 2

What makes SAE 8620 suitable for carburizing?

Accepted Answer

The low carbon content in SAE 8620 allows deep carburization, producing a hard, wear resistant surface while maintaining a tough and impact resistant core. This balance is crucial in high stress parts like gears and shafts.

Question 3

What industries commonly use SAE 8620 alloy round bars?

Accepted Answer

SAE 8620 is widely used in the automotive, aerospace, construction, and heavy machinery industries. It’s especially valuable in parts that need surface wear resistance and core toughness, like gear sets, pinions, and camshafts.
