Steel sheet is made of metal sections made of pure steel, combined with other elements. Steel or stainless steel sheet or stainless steel are produced and supplied in alloys and applications. In a general category, the steel sheets are divided into two groups of steel casts (a steel sheet that is absorbed by the magnet) and steel (a sheet of steel that is not absorbed by the magnet). In the general category of sheets, the second groups are more practical and more expensive at the same time. But in a more precise classification, steel sheets are classified according to the alloy: stainless steel sheet 304, stainless steel sheet 430, stainless steel sheet 420, stainless steel sheet 309, stainless steel sheet 310, stainless steel sheet 316, stainless steel sheet 201.

The stainless steel is 100% recyclable. The waste steel is melted and re-molded. 65 to 80 percent of the stainless steel is recycled worldwide.

Can stainless steel work at very high or low temperatures? Yes, the stainless steel is extremely resistant to extremely high temperatures (up to 1000 ° C) and very low (up to 200 ° C).

Who has named the steels (304, 316, …)? The American Iron and Steel Association first began to categorize and name stainless steel, providing physical and chemical characteristics as well as their production instructions. Steel sheet is a metal sheet with a stainless steel property. Significant features of the steel can be called brilliance, beauty, smooth surface, lack of rust or corrosion over time.

The stainless steel sheet has several distinguishing features as follows:

Stainless steel sheet, Shiny stainless steel sheet, Matte steel sheet, scratched steel sheet, Coated sheet steel, Refractory sheet, Anti-acid steel sheet, colored stainless steel sheet, Patterned stainless steel sheet.

What size sheet does it have? The sheet of steel is supplied as a galvanized sheet and oiled sheets in rolls and sheets. Rolls of steel sheets are usually produced in three widths of 100, 125 and 150 cm. The stainless steel sheets are manufactured and offered in a dimension of 1 * 2 meters and 1/25 * 2/50 meters and 22.2 * 44.2 meters and 1.5 * 3 * meters and 1.5 * 6 meters and 2 * 6 meters. Steel sheets are available in thicknesses of 1th to 50 pounds.

What is the weight of the sheet steel? The weight of the steel sheet follows the weight of iron, and due to its combination with elements such as chromium, the density of steel is 7.8. For example, the weight of a sheet of 2 m of the type of 304 is about 31 kg for 1 * 2 meters.

Which country is the producer of stainless steel sheet? Stainless steel sheets are not manufactured in our country and in the past have come from the United States, Japan and Germany, but today they come from China, Taiwan and India and South Africa.

Steel Series 300: The most common type of stainless steel is the 300 Series steel, which is divided into several types, such as 303, 304, 305, 316, 321 and 347, among them, the steel 304, is more widely used and most commonly used. Steel 304 and a number of other stainless steel products include 18% chromium and 8% nickel, and are therefore also known as Steel 8-18. Of course, the name of the stainless steel 8-18 does not refer to a particular type of steel, since it shows only the percentage of nickel and chromium alloy. In addition, the carbon of these steels is less than 0.08% and does not have a magnetism. Steel 316 after the 304 steel is the second most common steel among the austenitic steels. This stainless steel, also known as “Stainless Steel Grade Marine”, usually contains 16% chromium, 10% nickel and 22% molybdenum, and is therefore also known as Steel 10-18. Changes in chromium and nickel ratios and the addition of molybdenum have made it more resistant to erosion, especially chlorine-induced erosion, and therefore for devices that should be in contact with exhausting agents such as chemicals, solvents, and saline water are appropriate. This type of steel is usually used in making knives and cutting tools and kitchen appliances and is also suitable for marine installations.

What is the difference between Steel 304 and 316? Steel 304 contains 18% chromium and 8% nickel but stainless steel 316 contains 16% chromium 10% nickel and 2% molybdenum. Molybdenum is added to help in corrosion resistance against chloride (such as sea water).

In 1821, French engineer Pierre Barbati observed that with the increase of certain amounts of chromium to iron, rigidity and acid corrosion resistance increased significantly. Leon Gilea and Albert Portoine in 1909 in France explored the microstructure of chromium and nickel alloys altogether.

The most common type of stainless steel is the 300 Series steel, which is divided into several types, such as 303, 304, 305, 316, 321 and 347, the steel 304 among them is the more widely used and common.

stainless steel sheet 304: Due to the presence of chromium, it does not have a magnetic property, and since it is not absorbed to the magnet, it is referred to stainless steel in the so-called market. Magnetic stainless steel has a low carbon content, and chromium and molybdenum are the main elements in this alloy. This group is not hardened by heat treatment (due to the presence of low carbon) and are in all magnetic conditions. Steel 304 and a number of other stainless steel products include 18% chromium and 8% nickel, and are therefore also known as Steel 8-18. Of course, the name of the stainless steel 8-18 does not refer to a particular type of steel, since it shows only the percentage of nickel and chromium alloy. In addition, the carbon content of these steels is less than 0.088% and does not have a magnetism

Steel 316 after the 304 steel is the second most common steel among the austenitic steels. This stainless steel is also known as “Stainless Steel Marine Grain” and usually contains 16% chromium, 10% nickel and 2% molybdenum, and is therefore also known as Steel 10-18. Changes in the chromium and nickel ratio and the addition of molybdenum have made this steel more resistant to erosion, especially chlorine erosion. For this reason, it is suitable for devices that should be in high contact with corrosive agents such as chemicals, solvents, and saline water. The most widely used stainless steel sheet 304 is for use in the food industry and the milk industry. Due to the specific chemical composition of this product, the contact of this metal with foodstuffs, even corrosive materials such as milk, has no harm to humans and is very common.

The 304 sheet is the most used and most commonly used stainless steel plate in the following types of steel sheets in the market:

Shiny stainless steel sheet, matte stainless steel sheet, scratched stainless steel sheet

All types of top can be coated or uncoated (plastic).

Which country the 304 stainless steel sheet is produced? 304 is not produced in our country and in the past it has entered the United States, Japan and Germany, but now it comes from the countries of China, Taiwan and South Africa.

What is the Stainless Steel Sheet 304 size? The stainless steel sheets are manufactured and offered in a dimension of 1 * 2 meters and 1/25 * 2/50 meters and 22.2 * 44.2 meters and 1.5 * 3 * meters and 1.5 * 6 meters and 2 * 6 meters.

What is the price of a 304 sheet steel? The price of a sheet of steel 304 is more expensive than the price of a 430 sheet, and is cheaper than stainless steel 310 or stainless steel 309 or stainless steel 316.

What makes stainless steel to be stainless? The steel is stainless when it has at least 10.5% (ten and a half percent) of chromium. After combining oxygen with air, chromium forms chromium oxide, which forms a layer on the stainless steel. This layer can not be seen, but it makes the connection between air and metal disappear and the steel remains healthy. The greater the amount of chromium, as well as some other elements in the alloy like nickel and molybdenum, enhance this layer and increase the stainless steel’s anti-rusting properties.

Stainless Steel Series 400 and its Applications

Steel 410: It is abrasion resistant, but has a low resistance to corrosion.

Steel 420: the grade is special for cutlery and has good polishing ability.

steel 430:  is a special decoration grade. For example, it is used in car interior decoration. Most of the patterned steel is with the grade of 430 steel. This grade has a good ductility at low temperatures and is resistant to corrosion and due to lower alloying elements, the price is lower than the steel group 300 (steel 304, stainless steel 316, steel 321).

Steel 430

As we mentioned before, the steel sheet is made of metal sections made of pure steel, combined with other elements. Steel or stainless steel sheet or stainless steel are produced and supplied in alloys and applications. One of the most common and cheapest types of stainless steel sheets is the 430 stainless steel plate, available in two shiny and opaque types. Usually 430 sheets are uncoated and glossy on customer’s request with a small amount of cost. Stainless steel sheets 430 are absorbed by the magnet, and over time, even the rust is created. Stainless steel sheets 430 are usually used in basic cases that do not require moisture or acid resistance. Catch sheets or 430s are always one of the cheapest sheets of stainless steel and there is no significant difference between it and galvanized iron.

What is the size of the 430 steel sheet? The stainless steel sheets are manufactured and offered in a dimension of 1 * 2 meters and 1/25 * 2/50 meters and 22.2 * 44.2 meters and 1.5 * 3 * meters and 1.5 * 6 meters and 2 * 6 meters.

What is the weight of 430 steel sheet? The weight of the 430 steel sheet follows the weight of iron and due to its combination with elements such as chromium, the density of steel is 7.8. For example, the weight of a sheet of 2 m of 430 steel is about 31 kilograms for 1 * 2 meters.
