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]

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
