Introduction to Hot Rolled Stainless Steel Sheet Quotation Examples Advantages and Uses

There are many factors that affect the stainless steel clad plate series. And there are many aspects to consider in addition to **. It is recommended to learn about Weihai Chemical Machinery, and there should be some gains.

Founded in 1975, Weihai Chemical Machinery Co., Ltd. is a designated production enterprise and a domestic manufacturer of research, development and production of high-pressure reactors. After the restructuring of the company in 1998, it introduced the technology of metal composite materials, specializing in the research and development, production and sales of metal composite materials.

2.The feel is different: the cold-rolled plate feels delicate and smooth, and the corners are neat; The hot-rolled plate feels a little rough to the touch, and the corners are a little untidy.

3.The characteristics are different: the cold-rolled plate is hard, and the strength is high, and the production process is complex; The hot-rolled plate has low hardness and good ductility, which is convenient to make.

Stainless steel is stainless steel, and there is no such name as stainless steel cold plate.

2. The reasons for the residual stress of hot-rolled steel and cold-rolled steel are different, so the distribution on the cross-section is also very different. The residual stress distribution on the cross-section of cold-formed thin-walled steel is curved, while the residual stress distribution on the cross-section of hot-drawn or welded steel is thin-film.

3. The free torsional stiffness of hot-rolled steel is higher than that of cold-rolled steel, so the torsional resistance of hot-rolled steel is better than that of cold-rolled steel.

4. The cold plate is processed by cold rolling without oxide scale. The hot plate is processed by hot rolling, and the surface has oxide scale, and the thickness of the plate is different.

2.The cold-rolled steel section style is generally an open cross-section, which makes the free torsional stiffness of the cross-section low. It is easy to torsion when bending, and bending-torsional buckling is easy to occur when compression, and the torsional performance is poor;

Cold rolling: hot rolled steel coil as raw material, cold continuous rolling after pickling to remove the oxide scale, the finished product is rolled hard coil, due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard coil rise, and the toughness and plastic index decrease, so the stamping performance will deteriorate, and it can only be used for simple deformation of parts. Rolled hard coils can be used as raw materials for hot-dip galvanizing plants, because hot-dip galvanizing units are provided with annealing lines. The weight of the rolled hard coil is generally 6 tons, and the steel coil is continuously rolled at room temperature for the hot-rolled pickled coil. The inner diameter is 610mm.

Product features: Because it has not been annealed, its hardness is very high (HRB is greater than 90), and the machining performance is extremely poor, and it can only carry out simple directional bending processing of less than 90 degrees (perpendicular to the direction of coiling).

To put it simply, cold rolling is processed and rolled on the basis of hot-rolled coils, generally speaking, it is hot-rolled--- pickled --- cold-rolled.

Hot rolling is made of slabs (mainly continuous casting billets) as raw materials, and after heating, strip steel is made from roughing mills and finishing mills. The hot steel strip from the last rolling mill of finishing is cooled to the set temperature by laminar flow, and then rolled into a steel strip coil by the coiler, and the cooled steel strip coil is processed into a steel plate by different finishing lines (leveling, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) according to the different needs of users

Flattening coil and slitting steel strip products. To put it simply, a billet is heated (that is, the kind of red and hot steel in TV) after several rolls, and then cut the edge and corrected into a steel plate, which is called hot rolling.

The stainless steel products we see, some are as bright as mirrors, some are dull, some are hard and not easy to deform, and some are easy to break. Why is there such a big difference in the number of stainless steel products? In fact, the characteristics of stainless steel products are determined by the characteristics of their product plates.

On the market, there are many types of stainless steel plates, and different plates show different characteristics. Next, I will take you to know the different stainless steel plates. 

We all know that stainless steel plate has the characteristics of strong plasticity, corrosion resistance, no deformation, smooth surface and scratch resistance. According to the pressing and rolling method, stainless steel plate can be divided into two types: hot-rolled stainless steel plate and cold-rolled stainless steel plate. These two types of stainless steel plates have their own characteristics in addition to the commonalities of stainless steel.

Cold-rolled stainless steel plate. The advantages of this stainless steel plate are: good ductility, can be made into ultra-thin plate, high hardness, smooth surface.

The disadvantages are: **High, gray surface. Therefore, this kind of stainless steel plate is often used in the manufacture of vehicles and electrical appliances.

The performance of cold-rolled stainless steel plate is relatively stable and corrosion-resistant. Therefore, cold-rolled stainless steel sheets with a thin thickness are also often used for the packaging of food products such as canned food. This kind of stainless steel plate is grayish-white because of its natural appearance, so the general stainless steel household products do not use this cold-rolled stainless steel plate.

The matte stainless steel products we see in Nissan's life are made from cold-rolled stainless steel sheets. In the market, the best sales of hardware accessories and stainless steel kitchen and bathroom products are 304 stainless steel plate products. 304 quality of this cold-rolled stainless steel plate cold-rolled stainless steel plate 15 yuan per kilogram.

Hot rolled stainless steel plate. The advantages of this stainless steel plate: good surface gloss, low price, and good plasticity.

Disadvantages: low hardness. This stainless steel sheet making process is often used to make thicker stainless steel plates.

This kind of stainless steel plate is generally used in places where thicker stainless steel is required, and the toughness of this stainless steel is relatively good, and it is not easy to break and other accidents. Therefore, it is often used as a raw material for furniture and building materials. The market for this cold-rolled stainless steel plate of 304 quality is about 8 yuan per kilogram.

This hot-rolled stainless steel plate is often used in the production of hardware accessories, and the stainless steel hardware made of this plate has a good performance in terms of thickness and surface gloss.

The above is the basic situation of the two types of stainless steel plates, if the purchase of stainless steel plates is used for the production of precision instruments, it is recommended to choose cold-rolled stainless steel plates with high hardness and thickness accuracy. If the purchase of stainless steel plate is used for the production of large stainless steel products, it is recommended to choose hot-rolled stainless steel plate rubbing, because the thickness and toughness of this plate are better grasped, and it is also economical.

Introduction: cold-rolled stainless steel plate believes that it is an unfamiliar term for many people, what is cold rolling, cold rolling refers to under normal room temperature conditions. At the recrystallization temperature, the steel plate is rolled thin until it becomes the target thickness.

Compared with the common hot-rolled steel plate, the thickness of the cluster width of the cold-rolled steel plate is more accurate, and the surface is smoother. Here are some relevant information about cold osmosis Zheng rolled steel plate, let's take a look at it together. 

Cold-rolled steel plate is made of hot-rolled steel coil as raw material, it is first pickled to remove the oxidized outer skin, and then cold-rolled treatment, under normal circumstances, its finished product is rolled hard coil. However, due to the cold work hardening effect caused by continuous cold deformation, the rolled hard coil can only make some simple materials.

It is worth mentioning that cold-rolled steel plate can be used as a raw material for hot-dipting, because hot-dip units are generally equipped with some annealing lines. The weight of cold-rolled steel plate is generally more than six tons and less than 13.5 tons. At the same time, because the cold-rolled steel plate has not been annealed, its hardness is very high, and the HGB index exceeds 90.

However, there are advantages and disadvantages, because the hardness is extremely high, so its processing ability is very poor, and it can only be used for the processing of some directional small fish at 90 degrees.

So what is the difference between cold-rolled steel plate and hot-rolled steel plate, in layman's terms, cold-rolled steel plate is made on the basis of hot-rolled steel plate, usually its processing process is like this, line hot rolling, cold rolling at the end of pickling. Cold rolling treatment is carried out at room temperature, although in the process of processing, it is inevitable that there will be some factors that are the heating of the steel plate, but because the range of heating is not very large, so this process is still called cold rolling. However, because the cold-rolled steel plate formed after the hot-rolled steel plate is continuously cold-deformed after continuous cold deformation treatment, as mentioned above, although its hardness is very high, the mechanical properties are too poor.

After annealing, its mechanical properties can be restored. For those cold-rolled steel plates that have not been annealed, we also make them hard coils. It is used to produce some simple products.

Cold-rolled steel sheet has many uses, it can be used to make automobiles, produce electrical products, and the aviation food industry, etc. Cold-rolled steel plate is just an abbreviation, and its full name is also called ordinary carbon structural steel cold-rolled plate, and it is also called cold-rolled plate. The surface of cold-rolled steel plate is very smooth, and the dimensional accuracy is higher than that of other similar products.

And if it is those cold-rolled steel plates that have been annealed, its performance must definitely be superheated rolled steel plates.
