08AL has both cold rolled and hot rolled

This generally refers to cold rolling, but the grade 08AL is an old grade used around 2000, and most steel mills do not use this grade at present. It is possible that some small steel mills will also produce this grade of material.

At present, the commonly used cold-rolled grades are DC06, SPCC, SPCD, SPCE, SPCEN

Hot rolled has SPHC, SPHD, SPHE and Q235B, Q345B, SS400 and so on.

Among them, DC01 and SPCC, as well as SPHC, are all ordinary level. Then the further back you go, the better the stamping performance.

At present, 08AL is basically replaced by DC01 and SPCC, and if you want to stamp, you can use DC03 and SPCD.

08AL is generally cold-rolled steel.

08Al is a type of high-quality carbon structural steel, which is generally used as an AL deoxidized calmed steel cold-rolled plate in cold-stamped sheet steel. Its naming rule is similar to that of carbon structural steel, and its two-digit number indicates 10,000 times the average carbon mass fraction in steel, that is, "08" indicates the average carbon mass fraction in steel, and "Al" indicates aluminum deoxidation smelting and sedation. It is mainly used to manufacture various cold-stamping components below 6mm, such as body body, cab, various instruments and machine shells.

The cold-rolled steel plate is relatively thin!

The steel plate of Reza is relatively thick!

The excellent carbon plate can be either a cold plate or a hot plate, such as: 08al.

The general plate can also be a cold plate or a hot plate such as: Q235, the manganese plate can also be a hot plate or a cold plate such as: Q345, but most of the manganese plates are hot plates, and most of the general plates are also hot plates.

According to their own requirements, customers may make cold plates, hot rolled steel plate is the base material of cold rolling, which is made into cold plate through pickling, leveling, polishing and other processes.

The tensile performance of the excellent carbon plate is relatively good, and the tensile strength of the good manganese plate is relatively high, but the tensile performance is not very good.

In addition, the manganese plate does not belong to the excellent carbon plate, the excellent carbon plate is: the abbreviation of high-quality carbon structural steel, and the manganese plate has a relatively high carbon content. It belongs to the medium carbon plate or medium and heavy plate.

Tianjin Xiangyuxin Iron and Steel **** answered.

Excellent carbon steel is mainly distinguished according to the content of carbon.

Cold-rolled and hot-rolled plates are divided according to the processing method.

General plate generally refers to cold plate.

Manganese plates generally refer to hot plates.

Generally, it is a hot-rolled product. It depends on the user's requirements and what it is used for, and those who have special requirements for surface quality generally need to be pickled or galvanized in cold rolling!

The general plate generally refers to the cold plate, and the manganese plate generally refers to the hot plate.

I guess it means galvanized.

Hello, it's not too much of a problem, Cold rolled thin steel plate is the abbreviation of ordinary carbon structural steel cold rolled plate, commonly known as cold plate. It is made of ordinary carbon structural steel hot-rolled steel strip, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Due to rolling at room temperature, no iron oxide scale is produced, therefore, the surface of the cold plate is high, the dimensional accuracy is high, coupled with the annealing treatment, its mechanical properties and process properties are better than the hot-rolled thin steel plate, in many fields, especially in the field of household appliance manufacturing, it has gradually replaced the hot-rolled thin steel plate.

Applicable grades: Q195, Q215, Q235, Q275; SPCC (Japanese grade); ST12 (German grade).

Symbols: 1, Q - the code of the yield point (limit) of ordinary carbon structural steel, it is the case of the first Chinese pinyin letter of "yield" - the value of their yield point (limit) respectively, unit: MPa (n mm2); Because the strength, plasticity, toughness and weldability of Q235 steel and other comprehensive mechanical properties are the best in ordinary carbon structural steel, it can better meet the general use requirements, so the application range is very wide.

2. S-steel, P-plate, C-cold-rolled, and the fourth C-common grade.

3. ST-steel (steel - ordinary cold-rolled thin steel plate

Marking: Dimensional Accuracy - Size - Steel Plate Variety Standard.

Cold-rolled steel plate: steel grade - technical condition standard.

Cold-rolled ordinary thin steel plate: It is made of ordinary carbon structural steel or low-alloy structural steel cold-rolled. The surface quality of the cold-rolled plate is better.

It has good stamping performance. The requirements should be to ensure that the cold bending and cup tests are qualified, and they are often used in automotive and other industries and raw materials for plated plates. Cold-rolled high-quality thin steel plate:

It mainly includes a variety of high-quality steel cold-rolled sheets, the most commonly used is carbon structural steel plates, especially cold-rolled sheets for deep drawing, which are cold-rolled sheets made of low-carbon high-quality steel 08al, and the steel plates are divided into three groups according to surface quality; , respectively represents a particularly high-level, high-grade, higher finishing surface, according to the drawing level is divided into ZF, HF, F grade (on behalf of the most complex, very complex, complex parts used for punching drawing), according to the thickness of the steel plate allowable deviation, and divided into A, B two levels of precision, widely used in the automobile tractor industry.

Hope it helps.

XC75 is an alloy steel type structural cold-rolled steel.

XC75 cold-rolled steel strip, XC75 fine structural steel, XC75 round steel introduction:

Structural steel refers to steel that meets a specific strength and formability grade, and the formability is expressed as the elongation after the tensile finger test is interrupted.

Structural steel is generally used for applications such as load-bearing, where the strength of the steel is an important design criterion.

Structural steel can be subdivided into: alloy structural steel, carbon structural steel, low-alloy structural steel, heat-resistant structural steel, and so on. Less than low-carbon steel, especially 08F, 08Al, etc., which contain less carbon, is widely used as deep-drawing parts such as automobile canning ...... because of its good deep drawing and weldabilityIn addition, mild steel is also widely used as carburizing steel in the machinery manufacturing industry.

The difference between cold-rolled steel and hot-rolled steel is not in the smelting process, but in the rolling temperature, or the end temperature of the rolling. If the final rolling temperature is lower than the recrystallization temperature of the steel, it becomes cold-rolled steel. Hot-rolled steel is easy to roll and has high rolling efficiency, but the steel is oxidized under the condition of hot wear cover rolling, and the surface of the product is black and gray.

Cold-rolled steel requires high rolling mill power, low rolling efficiency, and intermediate annealing is necessary in order to eliminate work hardening in the rolling process, so the cost is also higher, but the surface of cold-rolled steel is bright, blind, and can be directly used to process finished products, which means that cold-rolled steel plate is widely used.
