Types of rolled steels
Types of rentals
- Stainless steel tubes. successfully used by the oil and gas industry and utilities, where the specificity of the use of rolled stainless steel tubes is very diverse;
- Stainless steel sheet is one of the most popular types of rolled metal products. It can be used as a billet for various products or used as ready-made product. Stainless steel sheet features a wide variety of surface types and sizes to meet the needs of companies involved in various industries;
- bar stock. This type of rolled products includes - channels, angles, strips, which are necessary to increase the stability and rigidity of large structures and construction. In mechanical engineering and machine tool construction such types of long products as circles, squares and hexagons are often used.
Wire
Stainless wire according to the method of processing is divided into light (oxide-free), as well as oxidized, by the accuracy of production - increased and normal accuracy, by physical properties - plasticity (first, second) class. Stainless steel wire is highly corrosion-resistant in corrosive environments. The most resistant are complex alloyed compositions with high percentage of molybdenum, copper, nickel and silicon. The grade with the required specified set of qualities is selected depending on certain specific conditions (concentration of aggressive factor and t°).
Demand
The most popular wire Ø 0,13 - 6 mm of the following grades: 17Х18Н9, 10Х17Н13М2Т (3T), 12Х18Н9Т (10T), 12Х18Н9, 304 AISI (08Х18Н10), 30Х13, 12 (20, 40) Х13.

Circle
Semifinished products of large diameters are called "billets", they are used mainly as blanks for mechanical engineering large parts. According to the type of production circle is divided into calibrated and hot-rolled, which is of normal, high and high accuracy. It is produced, as a rule, in short length of 1.5 - 5 m. Calibrated is cold-rolled and cold-drawn. Cross-section is usually Ø 5 - 270 mm. Small diameter (5 - 9 mm) products are supplied in coils, and with large cross-section are sold in stacks, which consists of straight sections. The following alloys are used for production: 08 (12)Х18Н10Т and 12Х18Н10Т-VD as well as monel.
Application
Circle grade 10Х17Н13М2Т is made of non-magnetic steel, which retains heat resistance up to +600 ° C and corrosion resistance in aggressive environments. It is usually used in the production of welded structures, and is widely used in the pulp and paper, food, medical, chemical, oil and gas industry, as well as in power engineering.
12X18N10T grade is often used for the most critical industrial parts as a semi-finished product. Its important advantage is plasticity and good machinability. It can retain mechanical, anticorrosive qualities at t° over 300 °C. A rod made of this steel is widely used in food, processing industry, as well as in the manufacture of mechanisms and parts that are constantly in contact with sea water and similar corrosive media.
For a circle of grade 20Х23Н18 is used high-alloy steel, which makes it resistant to corrosion and heat resistance, is used in the manufacture of parts for high-temperature installations with t ° operating over 1000 ° C.
Evaluation
All varieties of stainless bars have common requirements in relation to the quality of production, so in the process of purchase, it is necessary to pay attention to the surface of products to avoid cracks, delaminations. However, the presence of minor scratches, traces of broaching and sinks is acceptable.

| Wire | 0.1-16.0 mm | in a coil |
Tape production
To increase mechanical ductility and plasticity of tapes - steel is heated to 1050-1080 ° C, then it is hardened in water to give hardness. This hardening process strengthens the surface layer by means of plastic structural deformation. As a result, the products acquire high hardness and strength, but partially lose ductility and impact toughness. As the percentage of hardening increases, stainless steel becomes stronger but loses ductility. In addition to stainless high-tar and tungsten carbide tapes, there are also soft and semi-tungsten carbide tapes. They all differ in edge type, surface finish, accuracy and workmanship. As a rule the following grades are used for production: 12Х18Н10Е, 12Х25Н16Г7АР, 12Х21Н5Т, 12 (30) Х13, 08Х17Н5МЗ, 12Х17Г9А4, 12Х18Н9, 10Х17Н13МЗТ, 09Х15Н8Ю, 10Х17Н13М2Т, 20Х13Н4Г9 and others.
Use
Today it is difficult to find an industry that does not use stainless steel. Annealed strip, thanks to its high plasticity, can be used for corrugation - giving it any shape. Especially popular grades are - 12Х18Н10, 08Х18Н10 of chromium-nickel cryogenic and structural steel, with the addition of titanium. Such steels are heat-resistant and capable of withstanding t° up to 600 °C, having also high corrosion resistance. They are used in the manufacture of containers operating under high pressure, mainly in the food industry. Tape grade 12X18N10T is usually made soft, but after special treatment can become hardened. Due to their qualities, they are indispensable in the automotive industry, mechanical engineering, as well as in the manufacture of electrical devices.

Grade 10Х17Н13М2Т is resistant to high temperatures and aggressive environments that are saturated with chlorine. Special resistance gives molybdenum and titanium in the composition. Its resistance is five times higher than that of carbon steel. Grade 20X23H18 is indispensable in chemical, metallurgical, electromechanical and other industries. This is due to its resistance to corrosion when exposed to concentrated condensates and gases.

Similar properties have the brand 10Х17Н13М2Т, which serves as a material in the manufacture of units and machines that work reliably at high temperatures, in aggressive environments.
Seamless steel pipes
Seamless steel pipes without any welds or length joints are produced by rolling, pressing and drawing. They are the most popular today, and the most popular type is considered to be 12X18H10T grade pipes. So why are seamless pipes so popular today? No matter how skillfully and technologically the welded seam is made, it is impossible to rule out leakage, and if toxic liquids are circulating through such pipelines, then possible leaks must be completely excluded.
The advantage of seamless pipes is their reliability and durability, versatility and aesthetics, high anti-corrosive and protective properties. This pipe is an absolute guarantee of undesirable leaks in domestic communications (heating, water supply), as well as aggressive liquids. The use of stainless thin-walled and thick-walled pipe makes it possible to vary the metal capacity as well as the weight of the structure. Thin-walled stainless steel pipe gives lightness to the structure and is widely demanded, for example, in the furniture industry.
Flat rolled products
Steel sheet metal refers to the flat-rolled type. In addition to the temperature of processing on rolling mills, products of this variety differ in thickness, type of grinding and other parameters. In addition, flat-rolled products include tin plates, strips and coils.

-Rolling bar;
-hexagon;
