Carbon steel is the most common type of steel and contains about 0.1 to 0.3 percent carbon. In general, an increase in the amount of carbon reduces ductility but increases tensile strength and the ability to harden through tempering. As an industry-wide practice, steel that does not contain any specified or standard amount of one or more alloying elements to be classified as alloy steel (such as chromium, molybdenum, nickel, titanium, vanadium) is called carbon steel.

| Grade | Description |
|---|---|
| 19W4 | Heavy-duty carbon steel grating with a galvanized finish. |
| 40 | Used for rebar. Offers a minimum yield strength of 40,000 PSI. |
| 60 | Used for rebar. Offers a minimum yield strength of 60 KSI. |
| 1008 | Low-carbon steel containing approximately 0.40% manganese that has excellent weldability and formability. |
| 1011 | Hot-rolled carbon steel alloy sheet that exhibits high strength and high formability. |
| 1018 | Mild (low carbon) steel, strong and ductile, has good weldability properties. |
| 1045 | Medium carbon steel that can be forged satisfactorily. Most common shafting steel. |
| 1055 | Right on the border between a medium and a high carbon steel. |
| 1117 | This is a resulphurized steel with good machinability and surface finish, but not as good as the standard screw stocks. Its case hardening characteristics are superior and it develops an excellent core. It brazes satisfactorily but has no more than fair welding properties. A more ductile steel than others of lower manganese content and it cold forms well. Its machinability is rated at 89% of 1212. |
| 1144A | Medium carbon, usually cold-drawn. Can be heat treated. Welding requires special practices and residual control. |
| 1215 | Free machining steel, commonly referred to as screw machine stock, especially suited for automatic screw machine operations where the major requirement is exceptional free-machining quality with a smooth, bright finish. Poor weldability. |
| 12L14 | A standard resulfurized and rephosphorized grade carbon steel and a free machining steel. The added lead to the chemical composition provides improved machinability but the added lead content also reduces the overall strength of this alloy. |
| A36 | Low carbon steel that exhibits good strength coupled with formability. It is easy to machine and fabricate and can be securely welded. |
| A53 | Carbon steel pipe that covers seamless and welded black and hot-dipped galvanized steel pipe. It is used in pressure and mechanical applications and in steam, water, gas, and air lines. |
| A106 | Pressure tested. Ideal for high-temperature environments. Suitable for bending, flanging and similar forming operations. |
| A311-B | Excellent machinability, resistance to fatigue and stress, strengthened without heat treating. |
| A500 Gr-B | Standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. |
| A513 | Offers high weldability and is used frequently in structural applications in bridges and buildings as well as in both the automotive and appliance industry. |
| A514 | High strength steel, which is quenched and tempered with a yield strength of 100,000 PSI. |
| A516 | Medium carbon alloy used in pressure vessels and boilers. Contains manganese, phosphorus, sulfur and silicon at the highest levels allowed by the ASTM, to produce the strongest carbon steel plates specified by the ASTM. |
| A572 | Covers the standard requirements for Grades 42, 50, 55, 60, and 65 for high-strength, low-alloy, columbium-vanadium structural steel shapes, plates and bars for applications in bolted, riveted and welded structures in bridges and buildings. |
| A606 | Corrosion resistant. High strength steel. Excellent for welding, riveting, or bolting. |
| A706 | Low alloy. Easiest grade to weld. |
| A992 | Structural steel alloy often used for steel wide-flange and I beams. |
| AR 200 | High strength, low-alloy steel. Abrasion resistant. Made in the as-rolled condition. |
| AR 400 F | Quenched and tempered through hardened wear-resistant grades of abrasion. Used for high impact. |
| AR 500 | Standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. |
| AR-MED | High strength, low-alloy steel. Abrasion resistant. Made in the as-rolled condition. |
| C1045 | Medium carbon, medium tensile steel supplied as forged or normalized. This steel shows good strength, toughness and wear resistance. |
| CDS/HFS A519 | Good machinability, mechanical tubing great for tubes requiring thicker walls for high pressure and heavy duty applications. |
| DOM 1020 | Low hardenability and low tensile carbon steel. It has high machinability, high strength, high ductility and good weldability. |
| DOM 1026 | Nonresulfurized carbon steel. |
| HSLA GR50 | Medium carbon steel that can be forged satisfactorily. Most common shafting steel. |
| M1044 | Medium carbon steel used in general purpose applications when special quality is not required. It has good overall properties somewhat higher than low-carbon mild steel. |
| SAE J524 | Seamless, low carbon steel tubing. Annealed for bending. One of the easiest to bend. |
| SAE J252 | Welded and seamless steel pipe, in which the steel cylinder acts as a permanent load carrying member. |
