Technological properties of the material 10 ( 10, 10 ) . Weldability: without limitations. Flakes : not predisposed Temper brittleness: not predisposed
Specification :
Mechanical properties : s в - Tensile strength , [MPa] s T - Yield stress, [MPa] d 5 - 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
