ASTM A519 Alloy Steel Pipe
4140 / 4130 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.
4140 Meets ASTM A519
Cut to Length available
Benefits of Round 4140/4130 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.
Heating Specifications
AISI 4130 can be heated as a way to harden the material. When hardening is desired, the material should be heated at a minimum of 1600 degrees F. followed by an oil quench. The best results can be obtained when heating occurs between 1650 and 1700 degrees, followed by an oil quench and soak of 1600 degrees. If the material loses too much ductility during this process, the material can be tempered to restore some of the function. Tempering should be conducted at temperatures between 750 and 1050 degrees, depending on the resultant strength desired. The lower temperatures generally result in greater strengths during the tempering process. Heating can also be used to make the material easier to work with. Manipulation heating can be best conducted in a range of 2000 to 1500 degrees.
