Cold Rolled Steel Sheet Quality Standard SAE 1020 20# Thickness 2.5 mm 1250*2500mm


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.

Our Advantages

High precision
Cold-rolled high-quality thin steel plate: mainly includes various high-quality steel cold-rolled thin plates, the most commonly used is carbon structural steel plate, especially cold-rolled thin steel plate for deep drawing, which is cold-rolled thin plate made of low-carbon high-quality steel 08Al. The quality is divided into three groups;1 ,2 and 3, which represent particularly high-grade, high-grade, and higher-finish surfaces, respectively.
Extensive use
Cold-rolled steel plate with smooth surface and excellent processing, used for home appliances such as automobiles, refrigerators, washing machines, industrial equipment, and various building materials. With the development of the economy, cold-rolled steel sheets have been called necessary materials in modern society. Classification of cold-rolled products: hot-rolled pickling, hard-rolled coil, ordinary cold-rolled, galvanized (electro-galvanized, anti-fingerprint, hot-dip galvanized), galvanized, electro-tinned, color-coated, electrical steel (silicon steel sheet) wait.
Strict craftsmanship
Cold rolled steel coils generally use hot-rolled strip steel with a thickness of 1.5-6 mm as the cold rolled billet. The main processes include pickling, cold rolling, degreasing, annealing, leveling, and shearing (cross cutting, longitudinal cutting). If producing coated plates, there are also plating or coating processes such as electroplating tin, hot tin coating, and hot zinc coating. The production process of cold rolled billets is as follows: hot rolled sheet coils (raw materials) - acid washing - cold rolling - degreasing - annealing - leveling - shearing - finished product delivery.
Provide deep processing
The company's slitting machine, slitting line, cuts cold rolled steel coils into strips of various widths as needed, and then folds the strips into small coils for use in the next process. It is a necessary equipment for precision cutting of transformers, motor industries, and other metal strips. It is mainly used for strip cutting of materials such as tinplate, galvanized iron, silicon steel sheet, cold rolled strip, stainless steel strip, aluminum strip, steel strip, and other coils.
