Carbon Steel Introduction

Carbon steels have a higher carbon content than mild steel, to the extent that they rely on carbon content for their structure. The American Iron and Steel Institute (AISI) defines carbon steel as “steel that has properties made up mostly of the element carbon and which relies on the carbon content for structure.” They are much stronger, but less ductile, than mild steel.

Carbon steels are by far the most frequently used – more than 85% of the steel produced in the United States is carbon steel.

Most commercially available carbon steels are classified into one of three groups representing their carbon content: plain carbon, low-alloy, and high-alloy.

Plain Carbon Steels

Because they rely on carbon for their grain structure and, by extension, physical properties, plain carbon steels are defined almost entirely by their carbon content. They are broken down into the sub-categories of low, medium, high, and ultra-high carbon.

Low carbon steel typically contains 0.04 - 0.30% carbon. It is the most common grade among all carbon steels. This category machines easily, welds nicely, and is much more ductile than higher-carbon steel. Typical uses include automobile body panels, plate, wire products, forgings, seamless tubes, and boiler plate.

Medium carbon steel has a carbon range of 0.31 - 0.60% and a manganese range of 0.60 - 1.65%. It can be used in the quenched and tempered condition, with accompanying increases in hardness and tensile strength. The uses of medium carbon steels include shafts, axles, gears, crankshafts, couplings, forgings, rails, railway wheels, and rail axles.

High carbon steel contains 0.60 - 1.0% carbon and 0.30 - 0.90% manganese. It is difficult to weld; pre-heating, post-heating, re-heat treating, and sometimes even heating during welding is often necessary to produce acceptable welds. High-carbon steel is used for spring materials and high-strength wires.

Ultra-high carbon steel is an experimental alloy possessing carbon levels between 1.25 and 2.00%. It can be tempered to a great hardness level. Just like high carbon steel, welding can be tough, and controlled heat treatments are necessary to prevent cracking and to maintain physical properties. Ultra-high carbon steel is used for special purposes like knives, axles or punches.
