Buy Top Quality 4130 Chromoly Tubing, 4130 Chromoly Tube, AISI 4130 Pipe & Tube in USA.
Grade 4130 is a low alloy steel with additional reinforcement such as chromium and molybdenum added to its composition. The AISI 4130 Tubing is more amenable to treatments using heat or mechanical means than traditional carbon steels. The AISI 4130’s reduced carbon content makes for better welding processes.
4130 Chromoly Tubing, AISI 4130 Steel Tubing Manufacturer and Supplier in USA
Siddhgiri Tubes is a well-known 4130 Chromoly Tubing Manufacturer, Supplier in USA. 4130 Tubing are frequently provided in any of the following shapes: square, round, rectangular, as well as portions of a particular kind. A heat analysis could be used to limit the specified sections of the elements.
4130 Chromoly Tubing is a popular choice for structural applications due to its high strength and ability to be hardened. When low alloy steel is produced in accordance with ASTM A519 specification, it is either hot finished or cold finished.
The ASTM A519 Grade 4130 Tubing may be strand cast or cast in ingots if it is to be used as a component of mechanical tubing. Usually, steel is heated in order to create 4130 Alloy Steel Seamless Tubing. These hot-worked tubular pipes, if necessary, are then cold-finished to create the desired dimensions, shape, or qualities.
