American standard SAE1020 carbon structure cold rolled steel plate
Mainly used in: automotive steel, construction steel, cold/hot rolled steel, coil, coated, high-strength steel, color-coated coil and other steel products.
SAE1020 carbon structural steel plate has low mechanical strength, good plasticity and toughness, easy to deform in cold state, easy to cut and process, good welding performance, and can be carburized and cyanided to improve surface hardness. It is mainly used to manufacture low-strength welded parts, cold stamping parts, forgings and carburized parts such as bolts, washers, partitions, shells, etc.
The following are its chemical properties (smelting analysis): Carbon C: 0.16-0.22
Silicon Si: 0.15~0.35
Manganese Mn: 0.60-0.90
Sulfur S: ≤0.050
Phosphorus P: ≤0.040
Chromium Cr: ≤0.20
Nickel Ni: ≤0.25
Copper Cu: ≤0.25
Cold rolled steel plate is the abbreviation for ordinary carbon structural steel cold rolled plate, also known as cold rolled plate. Cold rolled steel plates are hot-rolled steel strips of ordinary carbon structural steel, which are further cold rolled to produce steel plates with a thickness of less than 4mm. Due to the fact that rolling at room temperature does not produce oxide scale, the cold plate has good surface quality and high dimensional accuracy. In addition, annealing treatment results in better mechanical and technological properties than hot-rolled thin steel plates. In many fields, especially in the field of home appliance manufacturing, it has gradually been used to replace hot-rolled thin steel plates.
