Briefing

4137H Hollow Bar offers good strength, weldability, impact and abrasion resistance while also being easy to machine.

Detailed

AISI 4137H Hollow Bar

 

4137H Hollow Bar 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. 4137H tubing stock is available in full size and custom cut lengths.

 

Advantages

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 harden using heat-treating or work hardening

MANUFACTURING PROCESS

Depending on the grade and type, alloy tubing is either produced per ASTM A519 or API 5CT industry standards. See CDS, HRS, or Boring 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 Forging + Boring/Drilling: Drilling is the process of removing material by using a drill bit. Drill bit is a long, sharp instrument, often with flutes, but it may have a variety of features depending on the work.
