4130 / 4140 Alloy Tubing are medium carbon alloy grades, which are widely used for many general purpose applications that require high tensile strength and toughness. The addition of chromium and molybdenum as alloying elements, combined with heat treatment, provides the combined advantage of hardness, ductility, and strength.

  • 4140 Meets ASTM A519 standards
  • 4130 tubing meets ASTM A519 Cold Drawn MIL-T-6736B Condition N
  • Stocked Size Range: 0.250” – 15” OD; 0.035” – 2.00” wall thickness
  • Stocked Lengths 8’-24’
  • All common offroad sizes available in 4130 tubing
  • Cut to Length available in 4140

Benefits of Round 4130/4140 Alloy Seamless Mechanical Tubing

  • Superior tensile strength and toughness
  • High strength to weight ratio
  • Easily heat treatable to a broad range of strength, machinability, and hardness.
  • Applications: aircraft components, hydraulic cylinders, rollers, structural applications
  • Control Arms, Roll Cages, A-Arms, 
  • Motorsport Chassis
