Description of physical characteristics

Parameter Units of measurement Description
Cp Дж/кг·К Specific heat of material
\alpha\cdot 10^{6}α⋅106 K^{-1}K−1 Coefficient of thermal (linear) expansion (range 20°C–T)
\varkappaϰ \frac{W}{m\cdot K}Wm⋅K Coefficient of thermal conductivity (the heat capacity of the material)
\rhoρ \frac{kg}{m^3}kgm3 The density of the material

Designation of types of weldability

Parameter Units of measurement Description
no limits Welding is performed without heating and without subsequent heat treatment
Boundedly welded Welding is possible with heating up to 100–120 °C and subsequent heat treatment
Difficult to weld For obtaining quality welded joints, additional operations are required: heating up to 200–300 °C for welding, heat treatment after welding — annealing
Not applicable for welded structures
