Stainless steel - steel with a minimum chromium content 10.5% - 11%. Stainless steel does not rust. It is also called corrosion resistant steel. There are different grades and surface of stainless steel in accordance with the environment. Stainless steel is used where the required properties of steel - resistant to corrosion. Stainless steel differs from carbon steel by the presence of chromium.

Types of stainless steel

This group of stainless steel has in common - the content of nickel, molybdenum, titanium, niobium, etc., which determines the properties of steel. Mechanical properties depend primarily on the chemical composition of the material. The correct choice of the brand guarantees a long and successful life. Due to its exceptional quality, the use of stainless steel is growing.

Stainless steel structure is divided into 5 categories:

  • Austenitic - contain nickel, which increases corrosion resistance. This group is the most frequently used.
  • Ferritic - low carbon, chromium at 13% - 17%.
  • Duplex - ferritic-austenitic characteristic.
  • Martensitic - usually contain 13% chromium and a moderate level of carbon.
  • Heat-resistant - are used to produce parts at operating temperature 550 C - 800 C.

Application

Stainless steel is used in all spheres of human activity, ranging from heavy engineering to electronics and mechanics. The most widely used in:

  • Construction and Architecture
  • Food industry
  • Household
  • Chemical and petrochemical industry
  • Pulp and paper production
  • Power
  • Environmental Protection
  • Transport engineering

Chemical industry

Almost all tanks, vessels, reactors, piping and other equipment of the chemical industry are made of stainless steel. Universal grade of steel for the chemical industry 10H17N13M2T (AISI 316Ti), with molybdenum 6%.

Food industry

Stainless steel is almost indispensable in the production of equipment for the production, storage and transportation of food due to high demands for hygiene, toxicity, etc. Hygiene is the most important in the food industry.

Stainless steel for the food industry uses grades 12X18H10T (AISI 321), 08H18N10 (AISI 304) and 10H17N13M2T (AISI 316Ti), in very rare instances, the high-alloyed. An important factor is flat and smooth (no kinks, bumps and scratches) in the metal surface.

Stainless steel is the ideal material for kitchen utensils. Nowadays it is fashionable to have a fridge and stove made of stainless steel.

Pulp and paper industry

Almost all of the production equipment of pulp and paper industry is made of stainless steel. The most common grade 10H17N13M2T (AISI 316Ti), but modern equipment is to be used with a minimum 6% molybdenum grade.

Modern large plants consume up to 5,000 tons of stainless steel per year (mainly pipes).

Energetics

Most of the world's energy is produced by burning natural resources (coal, oil, gas) or nuclear power plants. In both cases, the stainless steel is needed.

Transport

In the last few years has increased the need to transport a variety of materials and liquids. This problem was solved by the creation of special multi-purpose stainless steel containers and tanks. Between transfers enough to be washed and sanitized, and you can use it again. Thanks to this versatility used grades 10H17N13M2T (AISI 316Ti), also other steel grades. Transportation equipment - large market for stainless steels.
In the automotive industry, stainless steel is used for the production of pipes and exhaust catalysts.

Household

In the household stainless steel has found the widest use. This material is perfect for spoons, forks, pans, pots and other kitchen utensils. Also stainless steel internal parts are made of high-quality dishwashers and washing machines, grinders and juicers.

Construction and Architecture

Stainless steel offers a wide range of possible usage for designers and architects. It works well with other materials. Ideal for the facade and interior of buildings and premises. Beautiful roofing material. Garden furniture stainless steel looks nice and safe. Stainless steel is very practical at the same time noble and attractive. With a variety of grades and types of surface, it is able to meet the various conditions that are necessary for building needs.

Advantages

Нержавеющая стальTime of service

If we analyze the full life cycle of stainless steel - we can say that this is the most suitable material.

Ease of production

Modern methods of metal processing can easily be used for stainless steel production. Stainless steel can be cut, weld, press and process.

Corrosion resistance

Corrosion protection in normal atmospheric and aquatic environments, and can resist corrosion in many acids, alkalis, and some chloride solutions.

Strength

The mechanical properties of stainless steel can reduce the thickness of the materials, which reduces weight without compromising strength characteristics. Austenitic and duplex grades does not lose strength at low temperatures, even taking into account the smaller thickness than traditional varieties. Thus achieved significant savings compared to alternative materials.

Hygiene

Stainless steel is recognized as the most hygienic surface for food preparation. The uniqueness of the stainless steel surface has no pores or cracks for dirt and bacteria. Easily cleaned material, compared to other surfaces. Stainless steel - the first choice in strict hygienic conditions in hospitals, public kitchens, processing plants for the production of agricultural and food industry.

Aesthetic

Bright, easily machined surface of stainless steel provides an attractive and modern appearance of the product is ideal for architecture and decoration.
