Manufacturing Processes of 4130 Steel Tubing

The manufacturing processes of 4130 steel tubing are crucial in determining its final properties and applications. Typically, the production begins with the selection of high-quality raw materials, including chromium and molybdenum alloys, which are melted in furnaces to achieve precise chemical compositions. The molten metal is then formed into solid billets through casting or continuous casting processes. These billets undergo hot rolling or extrusion to create seamless or welded tubes of various sizes and dimensions.

Seamless 4130 steel tube is produced by piercing a solid billet through a piercing mill to create a hollow tube, which is then further processed through cold drawing or pilgering to achieve the desired dimensions and mechanical properties. On the other hand, welded 4130 steel tube is fabricated by forming flat strips of steel into a cylindrical shape and then welding the seam using various methods such as TIG (tungsten inert gas) welding or laser welding.
