Alloy Steel Round Bar

Alloy Steel Round Bar vs Alloy Steel Rod
Alloy steel is composed of different alloys that can be designed in the shape of round bars and rods. Both round bars and rods can be used interchangeably and can be distinguished on certain key features. 

  • Alloy steel rod is straight in size and can be shaped in circular cross sections. A rod is completely sealed with no openings.
  • An Alloy steel round bar is designed with a uniform cross-section area that is smaller in size compared to its actual length. A round bar can be characterized by a hollow opening.


What is 4130, 4150 and 4340 Alloy Steel Round Bars?

  • Alloy 4130 round bars is a low alloy steels grade having moderate resistance with excellent welding capacities.
  • Alloy 4150 round bars are designed with good alloying elements. These bars showcase outstanding hardenability and mechanical strength.
  • Alloy 4340 round bars have a higher carbon content and possess excellent toughness with good ductility.

What are En 353 Alloy Steel Round Bars used for?
En 353 alloy round bars are high-strength components that are hardened or tempered. These bars are common in gas turbine systems and automobile industries that are susceptible to high temperatures and require good resistance and fatigue life.

What is the difference between Hot Rolled Alloy Steel Round Bar and Cold Rolled Alloy Steel Round Bar?
AS round bars can be processed in a hot or cold rolling process. Both these processes are diverse and can be differentiated in certain aspects.

  • A cold drawn alloy steel round bar is processed at room temperature. Here the bars are run over dies to give the subsequent modules desired properties. A hot rolled alloy steel round bar is designed by heating the items at 1700 degrees F till they reach their recrystallization value. At this value, the bars can be shaped in correct dimensions easily.
  • A cold drawn bar possesses enhanced strength and surface finish when compared to a hot rolled bar.
  • Alloy steel cold drawn round bar has precise edges, while a hot rolled bar showcases rounded edges.
  • A hot rolled alloy steel round bar is cheaper than a cold alloy steel round bar.
