SPCC- stands for general-purpose cold-rolled carbon steel plate and steel strip, and the symbols are: S steel, P plate, C-cold-rolled, and the fourth C-common grade (mon).
Its chemical composition and mechanical properties are equivalent to those of China brands Q 195 and Q2 15A.
Question 2: What is the material of A3 cold-rolled sheet? Cold-rolled coil is made of hot-rolled coil at room temperature and below recrystallization temperature, including plate and coil, which can be produced by many domestic steel mills such as Baosteel, WISCO and Angang. Among them, sheet delivery is called steel plate, also called box plate or flat plate; Long and rolled delivery is called steel strip, also known as rolled plate.
Definition of cold rolling;
It is rolling under recrystallization, but it is generally understood as rolling with materials rolled at room temperature. Cold rolling of aluminum can be divided into plate rolling and foil rolling. The thickness above 0. 15~ is called a plate, and the thickness below 0. 15~ is called a foil. In Europe and America, 3~6 tandem mills are often used for cold rolling equipment.
Production technology: because there is no heating in the production process, there are no defects such as pockmarks and iron scales that often appear in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the properties and microstructure of products can meet some special requirements, such as electromagnetic properties and deep drawing properties.
Specification: thickness 0.2-4 mm, width 600-2000 mm, steel plate length 1 200-6000 mm.
Trademarks: Q 195A-Q235A, Q 195AF-Q235AF, q295a (b)-q345a (b); SPCC、SPCD、SPCE、ST 12- 15； DC0 1-06
Performance: Low carbon steel grades are mainly used, which requires good cold bending and welding performance and certain stamping performance.
Uses: Cold rolled strip steel is widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, canned food and so on.
Cold-rolled steel plate is the abbreviation of common carbon structural steel cold-rolled sheet, also known as cold-rolled sheet, commonly known as cold plate, sometimes mistakenly written as cold-rolled sheet. The cold plate is a steel plate with a thickness of less than 4mm, which is made of common carbon structural steel hot rolled steel strip by further cold rolling. Because the normal temperature rolling does not produce scale, the surface quality of the cold plate is good and the dimensional accuracy is high. In addition, its mechanical properties and technological properties are better than hot-rolled steel plates, and it has been gradually used to replace hot-rolled steel plates in many fields, especially in the field of household appliances manufacturing.

Question 3: What is the material of cold-rolled steel plate? Is it stainless steel 304? Cold-rolled steel plate is a broad concept, which can be made of various materials including 304 stainless steel.
Question: What is the material of C20 steel? C20 has never seen such a mark. Phonetic symbols are marked before 1958, as well as carbon 20 1 chromium 18, nickel and titanium. Later, we used the standard of Mao Zige, and then used chemical elements or pinyin letters, plus yield strength.

Question 6: What is the material of 6:STCC cold-rolled steel plate? STCC cold-rolled steel plate is made of low-carbon cold-rolled steel plate.
Cold rolled steel: thin iron sheet, usually a few millimeters, galvanized; The thickness of steel plate, generally above 3mm, also has1mm. ..
Cold-rolled steel: steel plate rolled without heating at normal temperature (strictly speaking, below recrystallization temperature).
Question 7: What is the material of cold-rolled steel plate T 1.5? You mean cold-rolled steel plates, right?
The material is carbon steel. T 1.5 represents the selected thickness.
Cold-rolled steel plates are made of hot-rolled steel plates (just like red molten iron in an iron furnace seen on TV)
Cold-rolled steel sheet has high strength and hardness after annealing. Poor flexibility.
After annealing, everything is better than the former, with good surface appearance, higher precision and good mechanical properties.
In short, steel plates can be used in different fields when they leave the factory under different processes.
The thickness of cold-rolled steel seems to be between 0. 1 and 8 mm, which is hard to remember. Go and check. Your 1.5 here is only one of the thicknesses.
I wonder if it will help you.
Question 8: What is the difference between cold-rolled steel plate and cold-rolled coil plate? Cold-rolled steel plate, that is, the box plate you usually see, has been squashed when it comes out of the steel plant. It is suitable for most manufacturing industries in the market. The common specifications are: 0.7-3.0mm materials are st 12, ST 13, ST 14, ST 15, ST 16, and ST factory 7. Because the mechanical group control is more accurate and the cold-rolled steel plate is more accurate when coming out of the steel plant, the general customers are willing to use cold-rolled steel plate, which is the so-called box plate, when there is no surface requirement. However, there are also some manufacturers or manufacturers who have requirements on board specifications, such as wider 1780 or narrower. Whether it is long or short, then cold-rolled coils are needed. Cold-rolled coil is just like the tape we see in our daily life, which wraps the cold-rolled steel strip, so it is called cold-rolled coil. Cold-rolled coils can be sized according to customers' requirements. It is more convenient to use.
