What grades of carbon steel do you have


Carbon steel is the most commonly used alloy steel, accounting for about 85 percent of all U.S. production. The carbon content of the product is in the range of 0-2%. This carbon affects the microstructure of steel, giving it legendary strength and toughness. These alloys also contain small amounts of manganese, silicon and copper. Mild steel is the commercial term for mild steel, in which the carbon content is in the 0.04-0.3% range.


Carbon steel type

Carbon steel can be classified according to the chemical composition and characteristics of the product. Mild steel also falls into the mild steel category because of its similar carbon content. Ordinary carbon steel, without alloys, can be divided into four categories:


1. Mild steel

Mild steel has a carbon content of 0.04-0.3% and is the most common grade of carbon steel. Mild steel is also considered mild steel because it is defined as having a low carbon content of 0.05-0.25%. Low carbon steel is malleable and highly malleable, and can be used in automotive body parts, panels and wire products. At the high end of the low carbon range, plus up to 1.5% manganese, the mechanical properties are suitable for stamping parts, forgings, seamless tubes and boiler plates.


2. Medium carbon steel

The carbon content of medium carbon steel ranges from 0.31 to 0.6%, and the manganese content ranges from 0.6 to 1.65%. The steel can be heat treated and quenched to further adjust the microstructure and mechanical properties. Popular applications include axles, axles, gears, guides, and railway wheels.


3. High carbon steel

High carbon steel has carbon content of 0.6-1% and manganese content of 0.3-0.9%. The properties of high carbon steel make it suitable for use as springs and high strength wires. These products cannot be welded unless a detailed heat treatment procedure is included in the welding procedure. High carbon steel is used for cutting tools, high strength wires and springs.


4. Super high carbon steel

Ultra-high carbon steel has a carbon content of 1.25-2% and is known as an experimental alloy. Tempering produces very hard steel, which is useful for applications such as cutting tools, axles, or punches.
