a | - Coefficient of linear expansion (range 20o - T ) , [1/Grade] |
l | - Termal (heat) condition coefficient , [Watt/(m·Grade)] |
r | - Density , [kg/m3] |
C | - Specific heat ( range 20o - T ), [J/(kg·Grade)] |
R | - Electrical resistance , [Ohm·m] |
Weldability : | |
without limitations | - welding is done without heating and subsequent heat treeting |
limited weldability | - welding is possible under heating up to 100-120 grade and subsequent heat treeting |
hard weldability | - obtaining the quality welding needs the additional operations:heating up to 200-300 grade; the heat treeting ia annealing |
