4130 Mandrel Drawn DOM Tubing

4130 DOM tubing 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 to makes it can be controlled and refined. Furthermore, Chromoly 4130 DOM tubing is like an improvement of grade 1030, which is considered mild steel.

Comparing 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.

Usages of 4130 Chromoly Round Tube

4130 mandrel drawn tubing 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
