Cold Drawn Carbon and Alloy Bars

Metal bars are the unsung heroes of numerous industries, silently fortifying the backbone of automobiles, machinery, and construction projects. Yet not all metal bars are created equal. Enter the world of cold-drawn carbon and alloy bars—a testament to precision engineering and metallurgical finesse.

Imagine a process where metal rods transform, emerging with enhanced strength, impeccable surface finish, and dimensional accuracy. That’s the magic of cold drawing. It involves pulling a metal rod or bar through a die at room temperature, refining its diameter, and elevating its mechanical properties to new heights.

This results in superior tensile strength, hardness, straightness, and surface quality for carbon and alloy bars compared to their hot-rolled counterparts.

These bars are ideal for use in applications where precision is paramount. Automotive components, machinery parts, and various construction applications rely on their exceptional mechanical properties and surface finesse. Their consistent dimensions and reliability make them indispensable, where accuracy is not just a preference but a necessity.

Cold Drawn Carbon Bars

Let’s delve into the carbon domain. Here are some noteworthy players:

1018

- Ideal for general parts and shafts requiring welding with moderate strength.

1045

- The go-to for gears, shafts, axles, bolts, and studs. It's versatile and suitable for flame and induction hardening.

1117/1144/1141

- Low and medium carbon resulfurized grades, offering superior machinability.

1215/12L14

- Tailored for screw machine applications, particularly small high volume machined parts. 12L14 shines with 30% higher machinability than its 1215 counterpart.

A311 cl B

- Designed for parts needing a minimum yield of 100ksi in-bar and excellent machining capabilities.

Digging Deeper into Alloy Bars

Moving into the alloy realm, these are among the most used grades:

8620

- The preferred choice for making gears that necessitate carburizing.

4140 Annealed and QT

- A versatile, heat-treatable medium carbon alloy. Perfect for shafts, axles, and gears that require through-hardening.

ETD 150

- Specifically crafted for parts demanding a minimum tensile strength of 150 ksi in-bar properties.

4340

- The heavyweight champion for parts needing profound hardness and toughness. Think demanding gear and shafting applications.

Cold-drawn carbon and alloy bars are meticulously refined to meet the stringent demands of modern industries. From boosting strength to ensuring precision, these play a pivotal role behind the scenes in diverse sectors that rely on their unwavering performance.
