Low carbon steels, containing up to 0.2% carbon, are used for truck beds, car parts, and structural shapes. Ultra-low carbon steels are used for steel panels and non-critical structural shapes. Carbon content affects strength and ductility, with high carbon steels being stronger but less ductile. Low carbon steels, such as 1010, 1018, and 1020, are commonly used for fasteners and bolts. 1020 steel has higher tensile strength and hardness values than 1010 steel.
Low carbon steels offer many applications. Truck bed floors, automobile doors, appliances, and spare tire pans are just a few things made with these types of steel. By definition, these steels can contain up to about 0.2% carbon by weight. Some of the most widely used low carbon steels include 1010, 1018 and 1020 steel.
The automotive industry uses a considerable amount of this steel to make parts that require simple bending or moderate forming. Truck cab backrests, tailgate access covers, bed frames, and bed floors are often made from this steel. Even the roofs, bonnets, doors and sides of ordinary cars are usually made with it. Other car parts, such as spare tire pans and dashboard panels, feature low carbon steel construction.
Ultra-low carbon steel contains only up to 0.05% carbon. Manufacturers often make steel panels from ultra-low carbon steels. These steels are also often used to create non-critical structural shapes for buildings. The carbon content of low carbon steel varieties generally ranges between 0.05 and 0.2 percent. They are often used to make beams and structural shapes for bridges and buildings.
Carbon in steel affects the ductility and strength of the material; high carbon steels are stronger than low carbon steels. Conversely, high carbon steels are less ductile than low carbon steels. The high ductility, however, results in poor machinability. Using higher spindle speeds on your machines makes machining these highly ductile steels much easier. In general, low-grade steels, such as some low-carbon steels with high phosphorus and high sulfur content, offer better machinability than cleaner, higher-grade steels.
1010 low carbon steel contains 0.10% carbon. This steel is a low strength steel but its strength can be increased through various tempering processes. Some types of fasteners and bolts are made from 1010 low carbon steel. One of the more popular varieties of low carbon steel is 1018 steel, which is relatively easy to machine, shape, and weld. Sprocket assemblies are often made from this steel.
The carbon content of 1020 steel can reach about 0.2 percent. 1020 low carbon steel is often used to make bolts and fasteners. The strength and ductility of this steel contribute to its widespread use. It can also be hardened to increase its applications. Compared to 1010 steel, 1020 steel offers higher tensile strength and hardness values.
