A513 carbon steel tubing products provide numerous advantageous qualities to a wide range of consumer and commercial industrial companies throughout the world.
SunnySteel Tubing produces round carbon and alloy electric resistance welded (ERW) mechanical tubing to ASTM specifications A513 Type1A (hot rolled), Type 1B (pickled & oiled) and Type 2 (cold rolled). Produced in sizes ranging from 1.05 inch OD up to 12.75 inch OD and in nominal wall thicknesses beginning at 18 gauge (0.049″) and heavier, ASTM A513 tubing is used in a variety of industrial, agricultural, and transportation related end uses. For a complete listing of sizes produced, please visit our Steel Tubing Product Catalog.
Tubing produced to the A513 specification also provide improved ductility with its closely controlled carbon steel grades.
ASTM A513 Type 1A & 1B
ASTM A513 Type 1A mechanical tubing is produced from hot rolled strip steel while A513 Type 1B tubing is produced from hot rolled strip steel that has been pickled to remove scale then oiled to provide a cleaner surface than hot rolled.
A513 Type 1 tubing provides more specific tolerances for OD, wall thickness, length and straightness tolerances than pipe and structural tubing specifications. It is often is used in applications where bending, flanging, flaring or flattening is required.
ASTM A513 Type 2
ASTM A513 Type 2 is produced from hot rolled strip steel that has been cold reduced. Due to the extra cold working at the steel mills, A513 Type 2 tubing will have tighter wall thickness tolerances, improved surface condition and a more narrow range of mechanical properties than A513 Type 1.
A513 Type 2 tubing is used in a variety of applications where surface condition is critical and where further polishing or plating of the tubing is required. The maximum wall thickness for cold rolled tubing is 0.120″ nominal.
ASTM A513 specifications state that manufactured carbon steel tubing must meet certain specifications before being sold for any type of project. The A 513 carbon steel spec sheet provides an accessible and straightforward way to check material standards before beginning your next project.

If a specific type of melting is required by the purchaser, it shall be as stated on the purchase order. The primary melting may incorporate separate degassing or refining, and may be followed by secondary melting, such as electroslag or vacuum-arc remelting. If secondary melting is employed, the heat shall be defined as all of the ingots remelted from a single primary heat. Steel may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The producer shall remove the transition material by an established procedure that positively separates the grades. Tubes shall be made by the electric-resistance-welded process and shall be made from hot- or cold-rolled steel as specified.
Chemical Composition
The steel shall conform to the requirements as to chemical composition. If no grade is specified, Grades MT 1010 to MT 1020 may be furnished.Analyses of steels other than those listed are available. To determine their availability, the purchaser should contact the producer. When a carbon steel grade is ordered under this specification, supplying an alloy grade that specifically requires the addition of any element other than those listed for the ordered grade permitted.
Heat Analysis
An analysis of each heat of steel shall be made by the steel manufacturer to determine the percentages of the elements specified; if secondary melting processes are employed, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The heat analysis shall comform to the requirements specified, except that where the heat identity has not been maintained or where the analysis is not sufficiently complete to permit conformance to be determined, the chemical composition determined from a product analysis made by the tubular manufacturer shall conform to the requirements specified for heat analysis. When requested in the order or contract, a report of such analysis shall be furnished to the purchaser.
A common question that comes up when buying tubing is the difference between A500 and A513 material. Customers often assume the specifications are interchangeable but when we delve deeper into the specs, we see there are significant differences.
What is A500 tubing?
A500 tubing comes in many different names – for squares and rectangles, it is referred to as structural tubing, or HSS (or Hollow Structural Sections). Rounds are typically called out as Structural Pipe or pipe size tubes. A500 products are used in applications where loadbearing applications are required. Because of its aesthetic appeal, A500 often is used as a showcase for architectural marvels such the Rock & Roll Hall of Fame in Cleveland, OH. When you order A500 tubing from the mill, you are supplied with an MTR, or Material Test Report that not only shows the chemical composition of the steel coil used to manufacture the tube, but also the Yield, Tensile and Elongation properties. The reporting of physical properties is one of the major differences between A500 and A513 material.
What is A513 tubing?
A513, or mechanical tubing, is used in more consumer based applications that need tighter tolerances but are not concerned with the load-bearing properties of the material itself. A513 applications can include lawn-mower handles or parts used in recreational vehicles.
Key Differences
When you are ordering A500 or A513 material from Sunny Steel, here are some of the key differences of both specs:
A500 |
---|
Looser Dimensional Tolerances (ex: 2×2-.083, Corner Radius max is .249”) |
Physical Requirements (Yield, Tensile, Elongation) |
Stenciling (required for material with a 5” or larger side) |
A513 |
---|
Tighter Dimensional Tolerances (ex: 2×2-.083, Corner Radius is 5/64” to .125”) |
No Physical Requirements |
No Stenciling required |
Sunny Steel supply square, rectangle, round and special shaped electric resistance welded (ERW) carbon steel tubing to meet ASTM specifications A500 Grade A, Grade B and Grade C that is often used in structural applications. The purpose and strength levels required will determine which grade is required.
Grade | Yield (min) | Tensile (min) |
---|---|---|
Grade A | 39,000 psi | 45,000 psi |
Grade B | 46,000 psi | 58,000 psi |
Grade C | 50,000 psi | 62,000 psi |
Grade | Yield (min) | Tensile (min) |
---|---|---|
Grade A | 33,000 psi | 45,000 psi |
Grade B | 42,000 psi | 58,000 psi |
Grade C | 46,000 psi | 62,000 psi |
