Key Features

  • Round metal tubing for use in aircraft and transportation structural applications
  • Alloy steel 4130 for more bendability and weldability than alloy steel 4140/4142
  • Seamless construction for a smoother bore than welded tubing
  • Meets MIL-T-6736B and SAE AMS6360 specifications for quality assurance

Product Description

This alloy steel 4130 seamless round tubing is suitable for use in aircraft and transportation structural applications. The tubing is seamless for a smoother bore than welded tubing. It is alloyed with chromium and molybdenum and has more bendability and weldability than alloy steel 4140/4142. This seamless round tubing meets MIL-T-6736B and Society of American Engineers (SAE) AMS6360 specifications for quality assurance and is suitable for use in applications such as bicycle frames and automotive roll cages.

Metal tubing, also called fractional tubing, is used to transfer liquids, air, or solids, and it is characterized by a round shape and a hollow center. Metal tubing is commonly made with various grades of austenitic stainless steel, aluminum, copper, brass, and titanium materials and their alloys. Construction types include seamless, welded, or welded and drawn. Seamless tubing has no seam or weld point, which enables it to better withstand high pressure and resist corrosion. Welded tubing, made by rolling and welding metal sheet stock, is weaker than and not as rounded as seamless tubing, but it has a more consistent wall thickness for tighter wall tolerances. Welded and drawn tubing, also known as "drawn over mandrel" (DOM), is typically welded tubing that is drawn through a die and over a mandrel to create a smooth inner diameter, which gives the tubing comparable corrosion resistance to seamless tubing while still offering welded tubing's tighter wall tolerances. Compression, vacuum, sanitary, and flared fittings connect tubing or redirect flow in a fluid handling system. Metal tubing is used in HVAC and plumbing systems and for applications in the aerospace, automotive, chemical processing, food and beverage, manufacturing, and medical industries.
