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
