Alro Steel was established in 1948 by Al and Robert Glick. Today, Alro is comprised of Alro Steel, Alro Metals, Alro Plastics and Alro Metals Outlet.

Carbon Steel Plate

Carbon Steel Plate

Low carbon steel plates are often used as a general-purpose tooling metal because of its mechanical structure and ease of machinability. Hot rolled carbon steel plate and sheet are ideal for drilling, grinding, and tapping. Carbon steel also provides exceptional welding properties for a range of applications.
Alro Steel stocks a wide range of carbon steel plate to meet your production needs. We can deliver cut to size and processed as needed. Popular processing options include thermal processing, milling, and grinding. Request a quote or contact us at 888-888-2576 to learn more about our carbon steel offerings.

What Is Carbon Steel Plate?

Steel is commonly considered carbon steel when no minimum content is specified for any alloying element (for example, aluminum, chromium, nickel, molybdenum, vanadium, etc.) or any other element added to obtain a desired alloy effect. The manganese does not exceed 1.65%, the specified minimum for copper is not below .40% or exceed .60%, and silicon does not exceed .60%. There are low, medium, and high carbon steel plates. The more carbon content in a plate, the more durable it becomes.

Carbon Content for Steel Plate

Carbon steel plate levels are divided as follows:
  • Low carbon = .06% to .25% carbon content (mild steel)
  • Medium carbon = .25% to .55% carbon content (medium steel)
  • High carbon = >.55% to 1.00% carbon content (hard steel)

Carbon Steel benefits

Carbon steel is most often mild or hot-rolled steel. As a corrosion-resistant and abrasion-resistant steel, carbon steel plates are well suited for applications requiring durability against stress and environmental stressors when used for outdoor purposes. Additional benefits of carbon steel plates include:
  • Versatility when compared to other materials, carbon steel plates are available in a wide selection of thicknesses and widths
  • Carbon steel plates offer excellent ductility
  • Cost-effective alternative to aluminum or stainless steel
  • Malleable and easy to fabricate
  • Can be galvanized for corrosion-resistance

Carbon Steel Plate Grades

Carbon steel plates are available in numerous grade options to serve your project needs. The following carbon steel sheet grade list explains the system used to recognize different grades:
  • 10XX = non-resulpherized carbon steel, with manganese 1.00% maximum (for example 1018, 1045 and 1050)
  • 11XX = resulpherized carbon steel (for example 1117, 1141 and 1144)
  • 12XX = rephosphorized and resulpherized carbon steel (for example 12L14 and 1215)
The second two numbers in AISI-SAE designations indicate the approximate carbon content for steel (for example, in 1018, the carbon range is .15% to .20%; .18% [shown as “18”] is the approximate carbon content).

Other Carbon Steel Shape Options

In addition to plate, carbon Steel is formed into BarsPipe and Tube, Sheet, and Structural shapes (Angle, Channel, Beams, Tees, and Re-bar/Re-rod). For Alro Steel’s range of carbon steel plate grades, see our product listing table below.
