Product Description

Free cutting steels are a group of steels that are specifically designed to be easy to machine or cut. They contain sulfur, lead, and other elements that help to reduce the amount of force needed to cut through the steel. This makes them ideal for use in manufacturing processes where a lot of cutting or machining is required. Some common examples of free cutting steels include 12L14, 1144, and 1215.

1.What is a round bar used for?

Round bars are used in applications that require precision machining, such as motor shafts, fasteners, gear pins, and load-bearing rods. Their uniform shape makes them ideal for rotating parts or CNC machining.

 

2.What is a round bar called?

The most common shapes are round bar (also called rod), rectangular bar (including square bar, the special case of equal sides), and hexagonal bar (usually called hex bar for short). Tube and pipe are similar, but have hollow centers and are traditionally not called "bar" in industrial usage.

 

3.What is the difference between a round bar and a rod?

Round bars range from 1/8 to 6 inches in diameter, while rods are finer, from 1/16 inches to 1 inch. Each metal has different uses and requires specific crafting techniques, resulting in varying sizes.

 

4.How strong is a round bar?

Compressive Strength
Round Bars: Round bars handle compressive loads very well because their shape helps distribute stress evenly. This makes them especially good for applications where the pressure is centred, as it helps them resist bending or deforming under heavy loads.

 

5.What does a round bar look like?

Round Bar is a long, circular solid metal bar that can be used in a wide variety of industrial, commercial, and residential applications. Our branches offer a range of mild steel round bars in 300 grade mild steel, with our standard diameters ranging from 6 to 50mm.
