The Uses of DOM and 4130

When beginning a project, it’s important to select the right type of metal tubing. If you are looking for a flexible metal, you may decide to use DOM tubing. But if you need strength, 4130-grade alloy may be the more reliable option. By understanding the difference between DOM tubing and 4130-grade alloy, you will be able to make the right decision for you.

What is DOM?

Uses of DOM

DOM tubing is superior to a traditional weld. That's why it's the go-to process for projects that require high pressure or large workloads. It's common in heavy-metal industries, such as auto, oil and gas, and aerospace engineering. 

This metal practice is generally used to create integral machine parts. Its output of strength and sturdiness stands out in motorcycle frames, mechanical bearings, and hydraulic cylinders. If you want a surefire way to secure an essential part, DOM tubing is your best source.

What is 4130 Chromoly?

4130 is an alloy steel grade known as Chromoly. Chromoly is a combination of the words "chromium" and "molybdenum." Both are imperative to steel alloying; chromium adds strength and toughness to the element, and molybdenum adds corrosion resistance and can endure extreme temperatures.

Chromoly steel possesses enhanced strength and hardness. As an alloy, it helps give steel different properties that can be controlled and refined. Furthermore, Chromoly 4130 is a step up from grade 1030, which is considered mild steel. 

Compared to other alloys, Chromoly rates high in corrosion resistance and power. It is heavier than aluminum alloys, though its strength to weight ratio lends itself to metal plans of considerable size and pressure.

Uses of 4130 Chromoly Round Tube

4130 is used in an array of components that keep major machinery intact. It's applied to high-torque equipment such as crankshafts and heavy-duty equipment such as conveyors.

Mechanics often choose to work with 4130-grade steel, using it for roll cages, gears, and race car parts. Rifle barrels and gas delivery tubing sometimes include it as well. Other uses of 4130 include the following:

• Molds
• Drill Collars 
• Bicycle Tubing
• Pins
• Machine Shafts
• Trophy Truck Frames
• Tie Rods
