Alloy Round Mechanical Tubing
4140/42 and 4130 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 specifications and tolerances
4130 Meets ASTM A513 Type 5(DOM) or A519 (CDS) specifications and tolerances
4140 Alloy Tubing Tolerances
Stocked Size Range
- (4140): 3.000” – 19.000” OD; 0.500” – 3.000” wall thickness
- Stocked in 17.000’ - 24.000’ random lengths (Cut to Length available)
Manufacturing Process
Depending on the grade and type, alloy tubing is either produced per ASTM A513 Type 5 or ASTM A519 industry standards. See CDS, HRS, or DOM manufacturing processes per the specific type and specification for more information.
Benefits of Alloy Round Mechanical Tubing
Strength
Alloy Tubing has superior tensile strength and toughness. It also provides a high strength to weight ratio.
Heat Treatable
Easily heat treatable to a broad range of strengths, machineabilities, and hardness’s.
Versatility
Alloy tubing is an excellent candidate for most processing techniques where strength is required and allows for many options due to its available sizes produced.
Machinability
4140 alloy tubing is easiest of the common alloy grades to be machined, with a minimal stock allowance for clean-up. It has excellent machining characteristics and is a medium carbon alloy.
Wide Range of Sizes
Alloy tubing can be manufactured to a large range of OD and wall thickness dimensions due to it being rolled bar and pierced or cold drawn.
