AISI 4130 Round Bars are an alloy steel that is noted for its good strength and weldability properties. It has a low carbon content and can be readily machined with excellent results. This type of steel is commonly used in applications such as aircraft parts, motor shafts, gears, fasteners, automotive components, and more.
The features of the AISI 4130 Steel Round Bar include high tensile strength, good yield strength, superior corrosion resistance, and great formability and machinability characteristics, along with being fairly easy to weld. They also offer excellent wear resistance due to the presence of Chromium, which prevents galling during use.
Table of Content
Due to its numerous advantageous qualities, AISI 4130 Alloy Steel Round Bars are widely used in the oil and gas industry, petrochemical applications, power plants, automotive parts manufacturing, and more. They can be found in valves, rods, barrels, and other components that require a high degree of resistance to wear and tear. In addition, these bars are also preferred for their superior strength-to-weight ratio, which makes them ideal for use in aerospace engineering projects.
