Specification :

Mechanical properties :
s_в	- Tensile strength , [MPa]
s_T	- 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 20^o - T ) , [1/Grade]
l	- Termal (heat) condition coefficient , [Watt/(m·Grade)]
r	- Density , [kg/m³]
C	- Specific heat ( range 20^o - 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
