ASTM A519 GRADE 4140 HOT ROLLED ALLOY STEEL SEAMLESS PIPES / TUBES

 

 

OVERVIEW

 

ASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing. The standard is also acceptable in the manufacture of piping. It is manufactured by hot working and then cold finishing the steel into round, square, rectangle or special shapes.

 

AISI 4140 Seamless Mechanical 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.

 

Benefits of Round 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 apps, truck and automotive parts.

Commom Applications

  • Back-up and support tooling
  • Fixtures
  • Gears and gear racks
  • Machinery parts and components
  • Mold bases
