4130 Alloy Cold Rolled Round Tube offers good weldability without compromising steel abrasion and impact resistance. It is commonly used in structural applications, including gears, fasteners, and welded tubing.
4130 Steel has good machinability, good weldability, and can be heat treated.
What's the difference between pipe and tube?
The way it’s measured and the applications it’s being used for.
Pipes are passageways. Tubes are structural.
A pipe is generally measured by inside diameter or ID.(IE: You could roll a 2" golf ball through a 2" NOM pipe.) Tube, on the other hand, is measured by Outside Diameter. (So your golf ball would have the same O.D. as the 2" tube.)
