| 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 |
