Feature

Brand 03Х20Н16АГ6 relates to manganese-chromium-Nickel austenitic steels. Smelted in electric arc furnaces. Production is carried out according to specifications and 14−1-3291−81 14−1-2922−80. Such steel is used in cryogenic engineering in the manufacture of welded large-size containers, which have been long under the pressure at t º a periodic change from 20 °C to -250°C.

Physical properties at 20°C

The density is 7.8 g/cm3; specific heat 481 j/(kg · K); modulus of elasticity of 19.6x10−4 N/mm2; temperature coefficient of linear expansion α = of 16.1x10−6/°C. the thermal Conductivity at 100 °C = 17.5 W/(m · K);

Resistance to corrosion

In the hardened state steel is resistant to corrosion not only in acidic environments, but in srednekislye, as well as in industrial condensation. In solution 15−55% HNO3 her durability similar to steel Х18Н10.

Technological parameters

Hot deformation is carried out at t° 1200−900°C. the Steel is easily punched, both hot and cold conditions. Because of the tendency to deformation hardening during cold forming, you need more force.

Welding

Steel is welded by manual or automatic electric-arc method, submerged arc, automatic argon-arc welding. Heat treatment of the welds is not required.

Properties of welded joints made by manual argonodugovoy welding (sheet tolin 16 mm).
