The following types of rolled products are produced: rounds, sheets, tubes, wires, strips. Pipes can be seamless - solid drawn and welded - electro-welded. The production of a circle is carried out by stamping the metal under a certain prescribed shape. Circles can be used in the form of forgings,
- chemical composition of alloying elements;
- allowable content of impurities;
- Absence of bubbles, shrinkage looseness, slag inclusions, cracks;
- mechanical properties;
- ultrasonic test;
- Geometry and dimensions (allowable deviations, surface quality, curvature).

Advantages of
High resistance to intergranular corrosion and to corrosion cracking in alkaline and chloride environments. Alloying promotes high-temperature strength and makes it possible to produce parts for power-type installations with this steel grade. It is used in the manufacture of high pressure tanks (vessels), as well as loaded parts, axles, bolts for fasteners. In the case of unstressed conditions it is possible to change this steel grade to another one with lower carbon content.
Welding
Alloy 03N18K8M5T-VD is welded by automatic and manual argon arc welding. During manual arc welding electrodes with a wire rod of steel Sv-03N18K8M5T-VD are used. Welding seams are not subject to formation of hot and cold cracks.
Use
Production of loaded parts for mechanical engineering and metallurgical equipment - axles, bolts for fasteners. Used in industrial chemistry for tanks (vessels) of high pressure, which operate in highly aggressive environments, at t° up to 80 °C.
