4130 Chromoly Tubing
Chromoly tubing is highly versatile and used for a wide range of applications including automotive, aerospace, bicycling, construction, and firearm projects. 4130 steel tubing offers good strength, weldability, impact and abrasion resistance while also being easy to machine. Because it's stronger than carbon steel, thinner-walled tubing can be used for the same purpose - as in bicycle parts - leading to the part having a lighter weight. 4130 tubing stock is available in full size and custom cut lengths.
Advantages
Round 4130 Chromoly tube and pipe is manufactured to withstand a wide range of elements, providing benefits and uses for many applications. Some of the strengths of using Chromoly tube include:Excellent strength-to-weight ratio
High tensile strength, ductility, and toughness
Lighter and more robust than carbon steel
Easy to weld, form, and machine
Ability to case harden using carburization
Ability to harden using heat-treating or work hardening
SIZE RANGE
OD : 0.250" - 3.250"OD Tolerance: +/- .005" (up to 1.500" OD), to +/- .010" (above 1.500" OD)
Wall thickness : 0.035"- 0.313"
Wall Tolerance: +/- 10% (For ID Over .500") to +/- 15% (for ID under .500")
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.1 CDS: seamless tube and pipe is produced by piercing hot billets and subsequent rolling which reduces their diameter and elongates them. This material is then passed through a die and over a mandrel plug to produce an accurate size and gauge which is the essence of the cold drawing process.
2 HRS: Hot rolled mechanical tubing is produced by heating a solid billet or bar and then rotary piercing it as it rotates on rollers. Then the final processing through multiple pass size-reducing mills occurs. Tolerances and finish are similar to other hot worked steel products. Range of sizes and grades are more restricted than cold finished by the nature of the process involved.
3 DOM: The manufacturing process for DOM round steel tubing begins with coils of steel, which are slit to the proper width for the desired tube size. The strip is cold formed and passed through an electric resistance welder which joins the edges together, under pressure, to complete the tubular shape. After testing the weld's integrity, the tubing is cut to length for further processing.
Applications
Round steel tube 4130 provides good weldability without compromising steel abrasion and impact resistance. It is also sturdy yet lightweight in applications requiring strength without additional weight.Some of the typical applications for 4130 round tubing include:
Motorcycle frames
Aerospace applications
Motorsport chassis
Aircraft gas delivery systems
Bicycle frames
Racecar roll cages
