Cold rolled steel: its strength is high, but toughness, poor solderability, relatively hard, crisp, bright surface.
Cold rolled steel is hot rolled coil as raw material, at room temperature in the recrystallization temperature below the rolling, including the plate and volume, many domestic steel mills such as Baosteel, Wuhan Iron and Steel, Anshan Iron and Steel can produce. Which is called the delivery of steel plate, Cold Rolled Steel also known as box or plate; length is very long, rolled into a steel called steel, also known as coil.
③ general cold-rolled steel: refers to the type of carbon steel rolled into the plate of the product (usually rolled into a roll), there are other bar, wire and so on.
Stainless steel refers to the addition of Cr, Ni and other elements of the alloy steel, which represents the steel is 304 stainless steel, Cold Rolled Steel stainless steel also distinguish between plates, bars, profiles, wire and so on.
④ cold-rolled steel: its strength is high, but toughness, poor solderability, relatively hard, crisp, bright surface.
Stainless steel: the appearance of the surface and the use of the possibility of diversification of good corrosion resistance, better than ordinary steel durable corrosion resistance is high, so the possibility of use of thin plate high temperature oxidation and high strength, it can fire at room temperature processing, Plastic processing because there is no need to surface treatment, so simple, easy to maintain clean, Cold Rolled Steel high finish welding performance.
We know that stainless steel is a kind of steel, which is divided into many kinds, such as ferrite stainless steel. Austenitic stainless steel, precipitation hardening stainless steel, etc., and cold-rolled steel is cold-rolled steel, it is only one of their own, unlike the "stainless steel" argument in general. When we buy stainless steel, according to their own needs to buy a different stainless steel, and the purchase of cold-rolled steel is the target to buy, buy back the material only cold-rolled steel such a, it must be clear.
Summary: cold-rolled steel is a kind of steel, said white cold-rolled steel is cold-rolled steel; stainless steel is a class of steel, this category is divided into many kinds, such as austenitic stainless steel, ferritic stainless steel; Cold-rolled steel is a target to buy, cold-rolled steel on a material, while the stainless steel is required according to their own needs to buy different materials of stainless steel.
Cold rolled steel is cold rolled steel production. Cold rolling is a steel sheet in which the No. 1 steel sheet is further rolled to a target thickness at room temperature. Compared with hot-rolled steel, cold-rolled steel plate thickness is more accurate, Cold Rolled Steel and the surface is smooth, beautiful, but also has a variety of superior mechanical properties, especially the processing performance. In general, cold rolled steel sheets require annealing, pickling and surface leveling before being delivered to the customer. The maximum thickness of cold rolling is 0.1 - 8.0MM the following, such as most of the cold-rolled steel plate thickness is 4.5MM below; and our company's cold-rolled steel products control in the 2.0 --- 2.5mm thickness, easy and template to connect , And strong and strong. Cold-rolled steel and hot-rolled steel is not the difference between the smelting process, but the rolling temperature, or rolling steel to terminate the temperature. The finish rolling temperature is lower than the recrystallization temperature of the steel to become cold rolled steel. Hot rolled steel is easy to roll, steel rolling efficiency is high, but hot rolling under the conditions of steel oxidation, the product surface is dark gray. Cold rolling steel requires high rolling power, low rolling efficiency, and the process of rolling in order to eliminate the hardening process but also for intermediate annealing, so the cost is higher, but the cold-rolled steel surface bright, good quality, can be directly used to process Finished, especially that cold rolled steel plate is widely used. Cold-rolled steel is very high strength, corrosion resistance, flexibility, it is suitable for the phenomenon of the above ground pressure. Although the cost of cold-rolled steel is high, but our company for the quality of the product, in order to the effect of customer construction, Cold Rolled Steel and the use of cold-rolled steel as raw materials. Can be reused, saving wood, energy saving, reducing the cost of construction.
