Cp | Дж/кг·К | Specific heat of material |
$$\alpha\cdot 10^{6}$$ | $$K^{-1}$$ | Coefficient of thermal (linear) expansion (range 20°C–T) |
$$\varkappa$$ | $$\frac{W}{m\cdot K}$$ | Coefficient of thermal conductivity (the heat capacity of the material) |

---|---|---|
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 |
