Low-carbon steel is distinguished by a low carbon-to-iron ratio. Low-carbon means that it contains less than 0.30 percent carbon. Mild steel, often known as low-carbon steel, is less expensive to make than medium-carbon and high-carbon steel. Low-carbon steel is more flexible than high-carbon steel, which may improve its effectiveness in some applications while reducing its effectiveness in others.
Low carbon steels can be used with anhydrous liquids, such as hydrocarbon solvents, or chemical streams with low water content.
Unless a corrosion inhibitor is included in the stream, low-carbon steels are often unsuitable for use with aqueous chemical streams. Low carbon steels in aqueous streams can also be used in instances where the equipment wall thickness is increased to provide adequate service lifetimes.
Medium-carbon steel has a larger carbon-to-iron ratio than Low-carbon steel, although it is still lower than high-carbon steel. Low-carbon steel has a carbon content of less than 0.30 percent, while medium-carbon steel has a carbon content of 0.30 percent to 0.60 percent & manganese from 0.60% to 1.65%. Medium-carbon steel is used in a lot of automotive parts. It's more durable and stronger than low-carbon steel, although it still has some ductility.
Medium-carbon steels are commonly used for railway tracks, train wheels, axle shafts, rocker shafts, crankshafts, gears, and equipment parts that require this mix of qualities due to their high strength, wear resistance, and toughness.
Heat treatment can only be performed on very thin areas, but alloying elements such as chromium, molybdenum, and nickel can be added to improve the heat treatment and hardenability of steel.
Hardening carbon steel is stronger than low carbon steel but at the expense of ductility and toughness.
High-carbon steel, obviously, has the most elevated proportion of carbon to press. It comprises over 0.60% carbon, in this way changing its actual properties. Otherwise called carbon device steel, it has around 0.61% to 1.5% carbon. With such a high carbon content, high-carbon steel is more grounded and harder however less flexible than low-carbon and medium-carbon steel.
Due to their high wear-resistance and hardness, high-carbon steels are used in cutting tools, springs high strength wire, and dies.
