Specification
Mechanical properties :
σB - Tensile strength [MPa]
σT - Yield stress [MPa]
δ5 - Specific elongation at fracture [%]
ψ - Reduction of area [%]
KCU - Impact strength [kJ/m²]
HB - Brinell hardness [MPa]
Physical properties :
T - Test temperature [Grade]
E - Young modulus [MPa]
α - Coefficient of linear expansion (20° - T) [1/Grade]
λ - Thermal (heat) condition coefficient [Watt/(m·Grade)]
ρ - Density [kg/m³]
C - Specific heat (range 20° - 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
