Hot rolled sheet: characteristics

How to calculate the weight and price of steel sheet

Metal sheet sizes:

• t—thickness of the metal sheet
• a is the width of the metal sheet
• b is the length of the metal sheet

1. Calculation of the theoretical weight of 1 steel sheet: Weight of 1 sheet (t) = t (mm) x h (mm) x a (mm) x 7.85 (kg/m3)
2. Calculation of the cost of 1 steel sheet: Price of 1 sheet (RUB) = Weight of 1 sheet (kg) x Price per 1 ton (RUB): 1000 (kg)
3. Calculation of the weight of 1 m2 of steel sheet: Weight of 1 m2 = Weight of 1 sheet: Area of ​​1 sheet (a x b)
4. Calculation of the price of 1 m2 of steel sheet: Price of 1 m2 = Price of 1 sheet: Area of ​​1 sheet (a x b)

.. | Sheet 2 mm hot rolled

Sheet 2 mm hot rolled

2 mm metal sheet is one of the most popular rolled products in use. It is convenient to use for the production of thin-walled profile or electric-welded pipes, channels, angles, and PVL sheets. It is used in construction, shipbuilding and mechanical engineering, the oil and gas industry, in heat and power engineering, for structural elements, various mechanisms, in the production of various household and agricultural equipment, instruments, decorative panels, in interior design, building cladding, and on personal plots. Corrugated sheet metal is made from thin sheet steel in rolls - for roofs, fences, walls and partitions. After rolling, the corrugated sheet is galvanized and painted for anti-corrosion properties. Sheet 09G2S is used at extremely low temperatures or at elevated temperatures, for parts exposed to pressure.

Sheet gk st3 2mm is valued for its low cost, smoothness, ductility, malleability and flexibility of the metal, the ability to make other types of rolled metal and various products from it, light weight and strength. Hot rolled sheets can be welded. Its light weight allows it to be used to make hoods, air ducts, and any lightweight structures. The disadvantage is the need for periodic painting and low fire resistance.

sheet metal is produced as follows:

2 mm hot-rolled steel sheets are produced on continuous lines, which, when heated at temperatures up to 760 degrees Celsius and high pressure, pass through numerous rotating shafts, become wider and thinner, and then cold-rolled to impart certain properties, smoothness and improve the quality of the metal . A heated sheet has scale and unevenness, but rolling initially cold metal requires more powerful machines. In addition, the cold-rolled sheet must be additionally fired and heat treated to relieve the internal stress of the steel. Therefore, hot-rolled sheet 2 mm is cheaper than its cold-rolled counterpart, and if there are no special requirements for the quality of the sheet, then hot-rolled sheet is used.

Sheet St3 2 mm is supplied by Novolipetsk Iron and Steel Works JSC, Severstal JSC, Zaporozhye Metallurgical Works JSC Zaporizhstal, Magnitogorsk Iron and Steel Works JSC, Chelyabinsk Iron and Steel Works JSC and others.

Steel sheet 2 mm is classified as thin sheet and is produced in accordance with GOST 19903 in terms of assortment. Such hot-rolled metal sheet 2 mm is produced in accordance with GOST 16523 and GOST 17066. Standard 16523 applies to all rolled carbon steel thin sheets for general purposes. The steel used is high-quality or ordinary quality. These can be brands 08ps, 10ps, St1 - 3ps. GOST 17066 requires high-strength steel; our company sells 2 mm sheets of steel grade 09G2S.

In terms of rolling accuracy, a 2 mm iron sheet can be of increased or normal accuracy. The edge of such a sheet can be trimmed or unedged. According to the flatness, the sheet is distinguished between especially high, high, improved and normal flatness. Sheet 2 mm hot-smoked can be deep and have normal stretchability. Its surface finish can be either high or normal.
