Hot-rolled steel coil
Product Description
Hot rolled, that is, hot rolled coil, which is made of slab (mainly continuous casting billet) as raw material, and is made into strip steel by rough rolling mill and finishing mill after heating. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and then rolled into a steel strip coil by the coiler. The cooled steel strip coil undergoes different finishing operations according to the different needs of users. Lines (leveling, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) are processed into steel sheets, flat coils and slit steel strip products.product category:1. Hot rolls can be divided into straight hair rolls and finishing rolls (split rolls, flat rolls and slit rolls).2. According to its material and performance, it can be divided into: ordinary carbon structural steel, low alloy steel, alloy steel.3. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welded gas cylinder and pressure vessel steel, pipeline steel, etc

201 Stainless Steel StripStainless steel strip is an extension of ultra-thin stainless steel plate, and is also a kind of steel plate used in industry. However, unlike ordinary steel plates, stainless steel strip has a longer shape, and its scope of use is also different from ordinary steel plates. At present, there are many varieties of stainless steel strips, and there are also many different production specifications. Different stainless steel strips use different categories. Cold rolled strip is a specially treated stainless steel strip product. It is another industrial steel strip product, which is made of stainless steel strip as the basic material and is processed by cold rolling mill at room temperature. The rolled strip has excellent characteristics such as smooth surface, flatness, high dimensional accuracy and good mechanical functions, and is often processed into rolls and coated steel plates. Cold rolled strip is widely used in tractor, car and other industrial manufacturing. Hot rolled strip is another kind of stainless steel strip, which has low hardness, easy processing, good ductility and other excellent characteristics, so it is often used as a thin plate.![Q235 Carbon Steel Plate]( "Q235 Carbon Steel Plate")
Q235 Carbon Steel PlateCarbon steel, on the other hand, has far lower chromium levels, and is instead a carbon-iron alloy with only a few other materials, if any, as part of its makeup. As a result, it can be referred to as ‘low-alloy’ steel. Both stainless steel and carbon steel feature this basic composition, but carbon steel can be defined by its carbon content. This is normally around 2-2.5%, however this often varies. Though susceptible to rust unlike stainless steel, carbon steel is often cheaper and has its own varying mechanical properties based on carbon content.![ASTM A36 Carbon steel bar/rod]( "ASTM A36 Carbon steel bar/rod")
