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.

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:
