Description

The A36 carbon steel square tubing has been hot rolled and meets American Society for Testing and Materials International ASTM A36 specifications. The A36 carbon steel grade is a structural steel that has better formability than 1018 carbon steel. The tubing has been hot rolled, a method of compressing metal between two rollers at a temperature above the material’s recrystallization temperature to attain the specified dimensions.Steel is an iron alloy with carbon and other elements that modify the steel to achieve specific properties. In general, steels with higher carbon content have greater strength, hardness, and wear resistance, while those with lower carbon content have more formability, weldability, and toughness. Carbon steels, which include most AISI-SAE grades in the 1000 range, are classified by their level of carbon content as low (below 0.3%), medium (0.3% to 0.6%) and high (0.6% and above). Alloy steels, which include AISI-SAE grades in the 1300 and 4000 ranges and above, incorporate elements such as chromium, molybdenum, and nickel to modify properties like machinability and corrosion resistance. Tool steels, which include most grades with a letter and number grade designation, have high carbide content for wear resistance, high hardness, and the ability to hold a cutting edge. Some tool steels are designed to resist deformation when used in elevated temperatures.Tensile strength, used to indicate a material’s overall strength, is the peak stress it can withstand before it breaks. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded.

  • Just what I needed to repair a recliner
Item Thickness String: 1/2 Inches Item Width String: 1/2 inches Wall Thickness: 0.065 Inches Item Length String: 24 Inches Number of Items: 1
Not much to say, its steel, its square tube, its the advertised size. My daughter's big dog still thinks he's a puppy and tried to jump into my wife's lap while the recliner was reclined. His giant self landed right on the corner of the foot rest and managed to break the square tube that lest the recliner motor raise the footrest. So ordered this tube, drilled a few holes, and an hour later saved myself $1000 not having to buy a new recliner. ... show more

Not much to say. It's a steel tube. I'm using it to raise the yarn guide on my Circular Sock Knitting Machine. It does the trick nicely.

  • Saved me lots of time.
Item Thickness String: 5/8 Inches Item Width String: 5/8 inches Wall Thickness: 0.065 Inches Item Length String: 12 Inches Number of Items: 1
Good price, very fast shipping. I got this metal tube faster than if I waited for the weekend to browse the home center or rummage the scrap yard. The rectangular tube I purchased was as described on this page: 0.625 x 0.065 x 12 inches. The tube may have pieces of trim or shavings inside. Be careful. The item was shipped in a thick cardboard tube that weighs as much as the metal. It's nice and sturdy to be used for an outdoor lamp extension. ... show more
