Specification :
Mechanical properties :
sв - Tensile strength , [MPa]
sT - Yield stress, [MPa]
d5 - Specific elongation at fracture , [ % ]
y - Reduction of area , [ % ]
KCU - Impact strength , [ kJ / m2]
HB - Brinell hardness , [MPa]

Physical properties :
T - Test temperature , [Grade]
E - Young modulus , [MPa]
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
