## Description

Alloy: 4130 | Material: Alloy Steel | Shape: Round Tube | Production Method: Seamless | Outer Diameter: 0.75 Inch | Inner Diameter: 0.62 Inch | Wall: 0.065 Inch | Item Length: 12 Inches Alloy Steel Round Tube 4130 Normalized Seamless offers good strength and weldability without compromising steel abrasion or impact resistance. 4130 can also be made even stronger through heat treatment. It is typically used in structural applications, gears, fasteners, and aircraft exteriors. Tube is designed to act as structural support, whereas Pipe is designed to carry liquid/gas/material from one place to another. Alloy steels are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium and aluminum. These metals are added to produce specific properties that are not found in regular carbon steel. The elements are added in varying proportions (or combinations) making the material take on different aspects such as increased hardness, increased corrosion resistance, increased strength, improved formability (ductility); the weldability can also change.
