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).
