Severstal is going to gradually replace stainless steel by bimetall. The company represents a wide range of bimetalls manufactured using electroslack surfacing and packing technologies. We will tell you more about the production and advantages of Bimetall further.

Bimetall is a composite material that consists of two or more different layers of metals or their alloys. They are firmly interconnected along the entire plane of contact.

There are three main methods of bimetal production: electric lane surfacing, package rolling and explosion welding.

Today, Severstal increases the production of bimetalls of electroslack surfaces and package rolling.

It is worth noting that the electric lane surfacing was developed at the Servica Cherepovets site. The company is the only manufacturer in the world that uses this method of making bimetallic sheets.

The main advantage of this technology is the independence of imports.

The production method depends on the thickness of the sheet. Thin sheets go to an electric lane surfacing, and thicker - on package rolling.

The domestic IT project SFERA can rightfully be considered the most ambitious project in the world. His release is not far off. The collection of registration applications is opened. To learn more about Sfera, follow the link.

In the production and operation of bimetallic sheets, a number of significant advantages can be distinguished.

1. Thanks to the combination of layers from various types of steel, it was possible to achieve high quality and greater strength.

2. Unlike rental, obtained by explosion welding by explosion, bimetall, obtained by package rolling and electric lane surfacing, has a uniform clutch area of ​​layers. This helps to avoid stratification both in the process of manufacturing equipment and during operation.

3. The economical use of scarce and expensive materials.

4. Increase in the corrosion resistance of the crying layer without its substantial rise in price.

It is known that initially the Severstal company planned to develop bimetall, 430 stainless steel. But the material that exceeds the 430th steel in characteristics was obtained.

Thanks to the high -haired low -carbon steel, which is the basis of bimetal, you can make parts of a complex shape.

Rolonnoye bimetallic rental is actively used in industry. For example, in the production of household appliances. It is also used in construction in the manufacture of facade cassettes. In the automotive industry, silencers and fuel tanks are made from it.

The company has plans for the production of pipe bimetal of small, large, average diameters. They can be used in the construction of emergency cooling systems in the nuclear energy.

How do you relate to the fact that Severstal has recently directed a large number of resources to technological transformation? What do you think this happened because assets are more impossible to withdraw abroad?
