Question 1

What is 8620 alloy steel round bars composed of?

Accepted Answer

8620 alloy steel round bars contains low carbon with added nickel, chromium, and molybdenum. This blend enhances its strength, ductility, and ability to undergo carburizing, which forms a hard exterior for wear resistance while maintaining a tough core for shock absorption.

Question 2

Why is 8620 alloy steel round bars preferred for carburized components?

Accepted Answer

The low carbon content makes 8620 alloy steel round bars ideal for deep carburizing. This heat treatment process hardens the surface while preserving a tough and ductile inner structure. It's commonly used for gears, camshafts, and bushings where surface wear and core strength are essential.

Question 3

What are the main applications of 8620 alloy steel round bars?

Accepted Answer

These bars are widely used in the automotive, aerospace, and machinery sectors. Common parts made from 8620 include gear teeth, shafts, fasteners, and pins. The material’s ability to withstand both high stress and wear makes it a go to choice for rotating or load bearing parts.
