Multipurpose Low-Carbon Steel Rectangular Tubes

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. These tubes are often fabricated into parts that don’t require high strength, such as frames, supports, and raceways. To increase their wear resistance, you can surface harden them with heat treating.

Multipurpose Formable 1050 Spring Steel Sheets

Containing more carbon than low-carbon steel—but less than 1095 spring steel—1050 spring steel is easily formed into parts such as washers, brackets, and springs before being hardened for use. It resists stress, so it won’t snap when formed or twisted. Because it has a lower carbon content than 1095 spring steel, it’s not as wear resistant.
