stainless steel metal

To maintain a high strength and corrosion products used stainless steel metal. For the needs of users invited to flat and long, metal products.

Corrosion Stainless Steel, composition, Properties and application of which are different from the manufacturing method and manufacturing techniques, It has been applied in most branches of the economy.

The price of products is quite high, however they provide the strength and quality of connections, endurance surfaces.

making

Stamps anticorrosive steel differ in the number and composition of dopants. The main component, providing anticorrosion nJ-steel is the presence of chromium, as well as nickel and molybdenum.

Stainless steel, by world standards should include at least 10,5% chromium.

Production technology

Stainless steel should exhibit the typical properties of steel, instead alloys with high contents of dopants. Plasticity and simultaneously provides structural strength peculiar construction of crystal lattice. For, to get the product, which will meet the quality standards, production is carried out using complex and high-precision process:

Smelting in an electric arc furnace;
smelting a high frequency induction furnace.
On stainless steel, brand products speak of the process of manufacture. for example, the presence of the mark HP – vakummno arc remelting. YOU – vacuum induction smelting, etc..

Further, stainless steel is manufactured by conventional techniques:

• • rafinirovaniya;
  • deoxidation;
  • heated to the desired temperature;
  • casting.

Stainless steel is not prepared in the open-hearth furnaces, as necessary to obtain a very low percentage of carbon availability. The converter does not give way to the right product quality and can not provide a stable chemical composition.

metal quality control should be sufficient to obtain important properties of the finished product, namely, the formation of an oxide film of chromium. The film occurs immediately after the creation of steel and is constantly updated. Oxide protection protects against corrosion and does not affect other materials, with which contacted stainless steel.

Stainless steel has a different rate for the presence or absence therein of large amounts of alloying metals, including rare earth. To understand the presence of specific elements can be carefully studying the markings, where it is indicated.

Fields of use

Anti-corrosion steel is used in almost all spheres of life and human activities:

• components for construction and energy;
• stainless steel food for food enterprises, tableware;
• cutting materials, including medical instruments;
• stainless steel for the chemical, oil, cellulose, textile and other industries, where resistance to aggressive media and strength;
• heat-resistant material, which can withstand temperatures of 300 to 800-1000 degrees;
• mechanisms and moves acid compound, requiring resistance to sulfuric and other acids;
• especially the important details of the aviation and other transport industry.

Directory of manufacturers and suppliers indicates the direction of the recommended use. It must be consistent with the design calculations or regular use practices. This applies to the industrial sector, where the characteristics are extremely important in creating new objects.

Range

Stainless steel products have a wide range of products, consisting of many subspecies. for example, anticorrosive steel sheet can be hot and cold rolling, which in turn is represented by conventional and thin-sheet subspecies. There are many kinds of width and length. Stainless steel pipes are offered in the form of seamless and electric varieties, which in turn are divided into hot and cold deformation. There is a division in the thin-walled and general purpose. Tubular products are usually offered it as a food grade stainless steel for the price, regulated length, wall thickness and diameter.

Stainless steel has a lot of other species and subspecies, which are issued for a specific industry, commercial, residential sector. for example, stainless steel food, anticorrosive materials for the manufacture of heat exchangers, boilers, steam pipes and other purposes.
