At O’Hare Precision Metals, we go beyond precision grinding services to provide our clients with exceptional carbon round bar stock.

As a trusted supplier, we offer high-quality carbon steel round stock that meets the demands of various industries. Let us guide you through the benefits and applications of carbon round bar.

Why Choose Carbon Steel Bar?

Carbon steel round bar, with a carbon content of over 0.08%, is widely utilized in construction, automotive, and other industries due to its impressive strength and corrosion resistance. It offers several advantages:

  1. Strength and Durability: Carbon steel stock is renowned for its high strength-to-weight ratio, making it ideal for structural applications.
  2. Cost-Effectiveness: Carbon steel round bar is affordable compared to other types of steel, providing a cost-effective solution for your projects.
  3. Easy Machinability: With the ability to be cut and shaped with ease, carbon steel round bar offers flexibility during fabrication processes.
  4. Wide Range of Applications: Carbon steel stock finds utility in industries such as aerospace, automotive, oil and gas, and more, due to its versatile properties.

Exceptional Grades and Shapes O’Hare Precision Metals offers a range of cold rolled steel bar and centerless ground bar stock, available in various grades, forms, sizes, and finishes. Our carbon steel round bar selection includes low carbons, medium carbons, and high carbons. We continuously expand our capabilities to meet the demanding requirements of diverse industries.

Unleashing the Potential The increased carbon and manganese content in carbon steels results in enhanced strength, hardness, and wear resistance after heat treatment. As the carbon percentage increases, the steel becomes stronger and harder. This makes carbon steel round bar a reliable choice for applications that demand toughness and durability.

Versatile Applications Carbon steel stock finds extensive use in the construction industry, as well as in aerospace, automotive, and oil and gas sectors. Its superior properties make it suitable for machinery, transportation components, buildings, bridges, ships, and various other structures.

Carbon Steel Grades: Strength, Machinability, and Versatility

Carbon steel offers a range of grades with varying properties and characteristics, making it suitable for a wide array of applications. From mild (low carbon) steel to high-carbon and alloy steel, each grade possesses unique qualities that cater to specific requirements.

Mild carbon steel grades, such as 1018, are known for their strength and ductility, making them ideal for applications that require good weldability. They are commonly used in crimping, bending, swaging, and the production of machine parts. These grades provide reliable performance and ease of fabrication.

For applications that require surface hardening and machining capabilities, grades like 1020 and 1030 are preferred. These grades can be case machined, hardened, and welded, making them suitable for components such as hydraulic shafts, motor shafts, pump shafts, and various machinery parts. With moderate hardness and machinability, they strike a balance between strength and ductility.

Higher carbon steel grades, such as 1035 and 1045, offer increased strength and wear resistance. They are commonly used in forged parts, gears, and shafts. These grades can be forged satisfactorily and are often employed in applications where durability and toughness are critical.

Additionally, there are specialized carbon steel grades like 1144, 11L14, and 12L14. These grades have enhanced machinability, making them ideal for applications that require superior machining capabilities, such as screw machines, couplings, and hydraulic fittings.

Carbon Steel Grades: Unlocking the Potential of Versatile Strength

At O’Hare Precision Metals, we offer a comprehensive selection of carbon steel rods in various grades and shapes. Our commitment to precision grinding services extends to providing top-quality carbon round bars. These round bar stocks are general-purpose and offer excellent weldability and formability. Let’s explore the benefits and types of carbon steel rods and their applications.

Types of Carbon Steel Round Bars

Carbon steel round bars are an iron-carbon alloy, typically containing about 2.1 wt.% carbon. They find applications in industries such as auto manufacturing, aerospace, shipbuilding, and more. At O’Hare Precision Metals, we offer different types of carbon steel round bars to suit diverse needs:

  1. Low-Carbon Steel: Widely used, low-carbon steel round bars have approximately 0.25 wt.% carbon content. They are not hardened using heat but through cold work. These round bars possess high ductility, making them ideal for low-cost machining and welding. They may also contain elements like nickel, copper, vanadium, or molybdenum for enhanced strength.

  2. Medium-Carbon Steel: Round bar stocks of medium-carbon steel have a carbon content ranging from 0.25 to 0.60 wt.%, along with manganese content of 0.60 to 1.65 wt.%. Heat treatment improves their mechanical properties, resulting in a martensitic microstructure. These hardened medium-carbon steel round bars offer increased strength but have lower ductility and toughness.

  3. High-Carbon Steel: High-carbon steel round bars contain carbon content between 0.60 and 1.25 wt.%. They provide high hardness and toughness, making them ideal for applications that require these characteristics. Despite lower elasticity, these hardened and tempered round bars offer high resistance to wear.

  4. Alloy Steels: Alloy steel round bars, including die steels and tool steels, may contain additional alloying elements such as chromium, molybdenum, or tungsten. These elements contribute to increased hardness and wear resistance, making alloy steel round bars suitable for demanding applications.
