Applications

1018 steel is a carbon steel that is commonly used in a variety of industrial applications. It is also known as low carbon steel, as it contains only 0.18% of carbon, which makes it a relatively soft and ductile metal.This type of steel is often used for parts that require moderate strength and toughness, such as gears, axles, studs, bolts, and couplings. It is also used in the manufacturing of machinery and equipment, such as machine parts and tools.
