Alro Steel was established in 1948 by Al and Robert Glick and has grown to include Alro Plastics, Alro Industrial Supply and Alro Metals Outlet.

Carbon Steel Pipe and Tube

Carbon Steel Pipe and Tube

Alro stocks carbon steel pipe and carbon steel tube in many grades and sizes. Our most popular structural grade is ASTM A500 carbon steel tubing. ASTM A500 is a standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square and rectangular shapes. A500 is the most common specification in North America for Hollow Structural Sections (HSS). 

Pipe and Tube Stocking Grades at Alro:

A500 Tube(round, square and rectangular), A500 Pipe, A53 Tested Pipe, A106 HF Seamless Tube, A513-T5 DOM Round Tube, A513-T2 CREW Round Tube, A513-T1 HREW Round Tube, A519 CD Seamless Round Tube, A519 HF Seamless Round Tube, A787 Round Tube, J524 Seamless Round Tube, and J525 Welded Round Tube.

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 in not below .40% or exceed .60% and silicon does not exceed .60%.

Carbon 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 grades are available in the following grade series:

  • 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).
